Using SIL Fonts in Documents and Publications – FAQ

Question: May I use SIL fonts in a document I plan to distribute in PDF format, or in a book I am publishing?

Answer: Please feel free to use SIL fonts in printed publications and PDF documents, including PDF documents posted on web pages. Such use is within the intended use of SIL fonts. No additional license or fee is required to use the fonts in a printed publication.

Many SIL fonts have been released under the SIL Open Font License. If you wanted to distribute SIL fonts not released under the Open Font License, you would need an OEM license.

Font use in digital images

Would use of these fonts in digital images be within their intended use as well, and no license fees would have to be paid?

Use of SIL fonts in phsical print-outs

Two questions:

1) Would use of SIL fonts in a physical print-out, that is creation of a 3 dimensional object, such as produced by Shapeways, be allowed, with no additional license or fee incurred? Please note that for a physical print-out to be made, the file provided to Shapeways would include a mesh which would be derived from the font. An example would be a medallion with text on it. The text mesh would be produced by typing some text in Inkscape, saving out as an SVG file, loading said SVG file into Blender, converting SVG text to mesh then extrude into 3d. This would then be saved as a mesh file, which is uploaded to Shapeways for print-out (in metal or plastic) and sale for profit to the public. Sorry for the lengthy explanation, but I thought it better to be explicit about the process and goals.

2)Since it is not possible to include a credit for the author of the font in the mesh file uploaded to Shapeways, would accreditation on a web site, or possibly the storefront of the seller at Shapeways surffice?

Re: Use of SIL fonts in phsical print-outs

Hi Lee! Yes: this usage is covered by our licenses (and no fee is required), and we don't require a credit for font usage. If you want to send us an image of the design or product (see e-mail address at the foot of this page), we're always interested to see how our fonts are used. Hope your project goes well!

We produce printed items that our customer designs on our website. The customer creates their design using their own text and selects from a list of fonts. Our server renders a preview of their design along with their text in their chosen font(s) and then the customer places the order. We then use the design created by the customer and print his product. Can we use these fonts for this purpose with no additional license?

You are not obligated to attribute an OFL font when you use it in a book or other document, but if you would like to, the wording suggested in the question would be fine. You may also want to include the short URL given at the top of each font's home page, to help others locate the font easily.

SIL Open Font License, 1.1

Hi there,

I wish to use a font that is licensed under SIL Open Font License, 1.1 in my mobile application which distributed in the app store (iTunes, Google Play etc). However, in the FAQ 1.1-update4, Question: 1.1.2, it states that it is not required to mention the font name, artist, etc in my work. But in Question: 1.20, it says if you bundle a font in the mobile app, you will need to include the copyright statement, the license notice and the license text. I'm just wondering does using the font (under SIL Open Font License, 1.1) in my mobile application (as text and graphics) consider as "bundle", should I include the font artist information in my mobile app? As it's rather confusing in both Question: 1.1.2 and 1.2.0. Hopefully someone could explain it to me. Thank you. :)

Re: SIL Open Font License, 1.1

Hi Jake,

Thanks for getting in touch with us about using an open font under the OFL in your app for mobile platforms.

There are a few aspects to keep in mind:

This may seem obvious but, if you are simply using graphics with text elements rendered from the outlines of the font that you have prepared earlier, then you are not bundling the font file itself into your app, you are simply using the font in the usual way and bundling the resulting graphical assets. You are very welcome to do this and you do not need any acknowledgement or propagation of authorship information. You remain the author and copyright holder of these derived graphical assets. Authors using the OFL for their font explicitly allow you to do that.

If you just bundle the original font (the font software) without modifying it then yes, you are also very welcome to do this; the OFL is explicitly designed to allow that even for restricted closed source software that you sell. You are not required to include the full release package of the font in your software (including OFL.txt, font source, documentation and so on), you can just put the font file you need in your source tree, but you should keep any copyright and licensing notices inside the font file itself intact.

To reformulate what section 1.20 of the FAQ is saying: you can bundle an OFL font but you can't strip away any authorship information and go out of your way to hide where it is coming from and that it is released under an open license. While not a strict requirement, an acknowledgement of the name of the font, its author(s) and the corresponding copyright and license with clickable links to their original webpages is usually appreciated in the About box of your software (or where you put other acknowledgement information such as other third-party libraries or assets you have used, or the changelog). It's easily done and doesn't take much space. This is quite common with many mobile apps nowadays.

Note that the font itself will remain under the OFL, but the app as a whole can be licensed however you wish.

You need to be aware that users who get your app are legally entitled to extract the font, reuse and redistribute it further under the terms of the OFL, even if your app is closed source.

However, if you modify the font to adapt it to the specific needs of your app (like adding extra styles or weights, removing character for size constraints, adding new characters for wider language support, or converting to different formats) then you are making a derivative version for which you need to pick your own font name (carefully respecting any Reserved Font Names declared by the previous authors). This is to make a clear distinction between your derivative version and the original version of the font and prevent any confusion for users. You cannot remove any existing copyright notices but only add your own afterwards to cover your modifications. You may also wish to contact the author(s) of the font directly and ask for help or expertise to make the modifications you need.

I hope this is clearer.

Wishing you success with your app.

Let us know if you have more questions.

Nicolas

 Reply
spalingern, Mon, Mar 23, 2015 07:06 (CDT)

Re: SIL Open Font License, 1.1

yes, I am pretty sure :-)

In short: you are allowed to just bundle the original font file you want inside your closed-source for-profit app, without all the other files of the release (like .txt files or documentation). An acknowledgement with name and link to the font website in your About box is good form and a nice gesture to the generous typeface designer but not legally required. The authorship information stays inside the font metadata in case someone later on extracts it. If you make a derivative version you need to pick your own name.

Is this clearer?

Modifying Font for Logo and Commercial Purposes

Hi there,

Is it okay if a SIL OFL font is modified somewhat and used for a logo for a commercial business or artist? This would be supplied as a vector graphic (using the outlines) to the artist or business if need be. Additionally, this modified logo would be used for branding and merchandise (which would be sold, such as t-shirts and mugs).

What option would be in your opinion easier:

* To convert it to .woff meeting the 2 requirements of the question 2.2?

* To use a web converter, and then change the name to the font?

Both seem a bit tricky to me and in both cases I would have to research how to do it.

Many thanks in advance.

The Webfont Kit tab for that font has a link to their webfont generator, along with an instruction to change the font name. That seems like the simplest approach.

Changing the name in the CSS and the font files would be enough? Or is it necessary to change the name in files metadata and things like that?

If the latter, could you please point me to any program that can assist me with that?

Many thanks.

 Reply
spalingern, Thu, Jun 25, 2015 10:54 (CDT)

Re: Converting to woff

For Modified Version you are required to change the name inside the font file itself (the names in the metadata fields of the font).

To make these changes you need a font editor like Glyphs or FontForge (there are command-line utilities but it's probably easier with a graphical editor).

Glyphs is proprietary, OSX-only but provides a trial version. FontForge is cross-platform libre software (open source) and can be downloaded at no charge: http://fontforge.org

Go to Element -> Font Info... -> TTF Names then right-click on the relevant entries to modify them.

See http://designwithfontforge.com/en-US/The_Final_Output_Generating_Font_Files.html for a screenshot.

BTW, beware of fontsquirrel optimizing away features that you actually want. Depending on the font it can be a good idea to see if the original author can help you with making a derivative webfont version.

According to the FAQ 1.20, if you include an OFL font in your application, "at a minimum you must include the copyright statement, the license notice and the license text." These would be files somewhere in your app package.

It would also be good, but not a requirement to mention "this information in your About box or Changelog, with a link to where the font package is from." So, credit is good but optional.

As mentioned in FAQ 1.20, you do need to put the copyright statement, the license notice and the license text files in your app, even if you don't change the font. "Bundle" in this case refers to including the font in your app.

It would be good to give credit to the designer, since you benefit from the designer's work, just as you would credit any other components you are using in your app. But it isn't a requirement.

Re: Wordpress Theme Bundling

short version: yes, you can do this if you sell a font under OFL within a software bundle, and you don’t need to ship the whole of the font’s documentation. You can’t sell a font under OFL if there is no software besides CSS and image assets. You need to change the fontnames if you modify the fonts.

If you just bundle the original fonts without modifying them, then you are very welcome to do this; the OFL is explicitly designed to allow that also for software packages that you sell (even for restricted closed source software or firmware). Bundling an open font with your plugin is allowed. Wordpress themes do include actual software like JS and PHP and not just stylesheets and image assets, right? The OFL allow selling a font within a bundle but bundling only with simple data is really selling on its own with is not allowed. So you need to make sure you are shipping software with the font not just data.

You are not required to include the full release package of the font in your software (including font source, documentation and so on), so you can just put the font file you need in your source tree, but you should keep any copyright and licensing notices inside the font file itself intact.

An acknowledgement of the name of the font and its author(s) with clickable links to their original webpages is usually appreciated in the Readme or About box of your component (or where you put other acknowledgement information such as other third-party libraries or assets you have used, or the changelog). It's easily done and doesn't take much space.

Re: Icon set

If I understand correctly, you're wanting to use SIL fonts to create some icon images, and then sell the icon image set. That's fine. However, if you're creating an icon font containing icons outlines (shapes) and you want to include some outlines from an SIL font then use the contact form to let us know which SIL font, and we can correspond with you about it.

Question about emoji artwork usage

I'm interested in using Google's Noto emoji artwork, which seems to be licensed under OSL, to make sets of patterns that will be sold. Basically, I am using the flower emoji artwork .svg file to make a pattern image that will be part of a larger set.

The set will contain my own artwork as well so that I won't be selling font parts individually. Is this acceptable use or not? I ask because I ran across the artwork on Wikipedia Commons. Thank you.

Re: Question about emoji artwork usage

If you are using an OFL-licensed font to produce images (and not other fonts), you can sell the resulting images. See the OFL-FAQ, in particular, questions 1.1 and 1.1.1.

All the best,
Peter

Re: Games and Books

Hi Alessia,

If you're using OFL-licensed fonts in print products like books and physical games, i.e. the font shapes are part of the design, you just use the fonts the same as any others (see FAQ Question 1.1.1).

If you are developing game software and actually dsitributing the font files with the product, then read the FAQ Question 1.4, and ensure that you include the whole font package including the OFL.txt copyright and license file.

All the best,
Peter

Creating greeting cards app

Hi! Does OFL also include using them in an app where users can edit templates using these fonts?

Thank you.

Re: Creating greeting cards app

Hi Monica,

A user can freely use an OFL-licensed font in any app. If you are asking whether you can distribute OFL-licensed fonts as part of an app, you can do that too, but see this FAQ question http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=ofl-faq_web#2a57c6bb for more information on the requirements.

Hope this helps!

Converted OFL 1.1 font format in embedded device

Hi,

we are developing an embedded device which will use a proprietary "rasterized" version from an original OFL font file, without modifying the font appearance itself.

This proprietary font file will be saved in the device filesystem, which is directly accessible only to our customer service. However, we may send to customers an update package with those proprietary format font files inside. Final users may get the font files in this way (by opening the archive package file), however the format will not be known to them, so they cannot use them in any way outside of our device.

My question is:

- should we add license files in the device filesystem together with installed font files?

- should we add license files in the update package that may occasionally be distributed to customers?

- should we add an about window in our embedded device with a font attribution message?

Thank you very much in advance.

Re: Converted OFL 1.1 font format in embedded device

Hi Fabio,

Thanks for asking this question. I'm going to check with maintainers of the OFL license and get back to you.

Re: Converted OFL 1.1 font format in embedded device

Hi Fabio,

- should we add license files in the device filesystem together with installed font files?

Yes. The license (or a link to it) must be provided.

- should we add license files in the update package that may occasionally be distributed to customers?

Only if you are adding new fonts to the device that were not there before. Updating existing fonts would not need it IMHO.

- should we add an about window in our embedded device with a font attribution message?

That would of course be welcome, but is not a requirement.

Have a look, too, at OFL FAQ 1.21

Some further info:

- If you just bundle the original fonts without modifying them, then you are very welcome to do this; the OFL is explicitly designed to allow that even for restricted closed source software or firmware that you sell. It will bring value to your product.
You are not required to include the full release package of the font in your software (including OFL.txt, font source, documentation and so on), so you can just put the font file you need in your source tree, but you should keep any copyright and licensing notices inside the font file itself intact.
An acknowledgement of the name of the font and its author(s) with clickable links to their original webpages is usually appreciated in the About box of your software (or where you put other acknowledgement information such as other third-party libraries or assets you have used, or the changelog). It's easily done and doesn't take much space.

You need to be aware that users who get access to your firmware might be legally entitled to extract the font, reuse and redistribute it further under the terms of the OFL.

Alternatively, if you bundle in your device any graphical assets derived from the font (bitmaps, vectors, outlines, etc), you are simply using the font in the usual way. You are very welcome to do this and you do not need any acknowledgement or propagation of authorship information. You remain the author and copyright holder of these derived graphical assets. Authors using the OFL for their font explicitly allow you to do that.

All the best with your project,
Peter

Re: Converted OFL 1.1 font format in embedded device

Hi Peter,

thank you for your prompt answer.

I have a doubt regarding FAQ 1.21:

in our case we took the original font files (.ttf) and converted to our proprietary raster binary format to multiple files with different pixel size (e.g. fnt10.bin, fnt14.bin, fnt22.bin), without modifying the character shapes, although some characters have been discarded because unused.

Is it enough to include the original license files for the original font (Source Han Sans), maybe with some reference to our files (a readme.txt like: "fnt10.bin, fnt14.bin and fnt22.bin are 'Source Han Sans' font files covered by SIL Open Font License 1.1, see license.txt")?

Are there any particular restriction to the font file names (fnt10.bin, fnt14.bin, fnt22.bin)?

I do not fully understand if this applies to our case: "If you do transform the fonts and change their formats when you include them in your firmware you must respect any names reserved by the font authors via the RFN mechanism and pick your own font name." Should we pick another name? And license it with OFL?

Thank you.

Re: Converted OFL 1.1 font format in embedded device

Since you modified the fonts, and since Adobe has "Source" listed as a Reserved Font Name, you must change the internal name of the font to something else that doesn't include the word "Source". That can be something as simple as "CompanyNameDevice", and your read me can say something like:

'Device fonts (CompanyNameDevice) copyright (c) 2016 YourCompany, based on Source Han Sans fonts copyright (c) YEAR Adobe...'

The font file names are not important, since they're not normally presented to the user. There is also no need to declare your name as a new Reserved Font Name.

Usage in App Store

My understanding is that the GPL-FE license is not compatible with app store since it prohibits the ability for apple to impose additional restrictions

Does OFL suffer the same limitation, or is it completely allowed (both from SIL and Apple's perspective) for usage in bundling with apps? Assume an unmodified packaging of the font in the resources of the app.

Can I use fonts under SIL Open Font License, 1.1 like this?

Hi,

Sorry for bothering you, but I'm a bit confused about font licensing.

I have a question about Source Sans Pro and Source Code Pro fonts.

I'm not sure if I really should ask you or Adobe as font's creator is Adobe,

but font's license is SIL Open Font License, 1.1. I hope I'm in the right place.

I'd like to know if I can use Source Sans Pro and Source Code Pro fonts, which are

both published under SIL Open Font License, 1.1, for my vector illustrations that I intend to sell.

https://www.google.com/fonts/specimen/Source+Sans+Pro - link for one of the fonts

These fonts will be part of my illustrations and used as titles (Sample Text, Lorem ipsum, etc.),

paragraphs, etc. The fonts will be outlined, i.e. I will use it only as outlined vector graphic

(fonts will be converted to curves) inside my illustrations.

Also, as I'm selling only eps and jpg files and I have no option to mention any font creators

and provide any txt file, any license file along with my product.

I've read OFL SIL License, but I haven't found any proper answer for my specific question.

Can I use these fonts like I described? Do I need to contact to Adobe anyway

or get the answer from you will be enough?

Thank you so much for your time!

Best regards.

Re: Can I use fonts under SIL Open Font License, 1.1 like this?

Hi John,

You're welcome to use outlined OFL fonts in design work, and acknowledgement somewhere is appreciated but not a requirement. Your intended use of OFL fonts as outline text in graphics is covered in the OFL-FAQ questions 1.1, 1.1.1 and 1.1.2.

Making sure I do everything right

Hi,

I am building and android app which allows the user to select different font files for the text they add and after that, save the text over an image. From what I understand, adding the font files into my app's APK files, means that I am bundle-ing them. The app is closed source and may be sold or offered for free.

Here is what I plan to do:

1. Download the fonts I need, usually I use Google Fonts (which I understand are SIL) or other sites witch state that "Type are subject to the Open Font License."

2. in my app's project source, I ONLY add the font file name, for example FontFile-Regular.ttf. I do not need to include any txt file content or other ttf files that I don't need from the font archive.

3. When I preview a font file, in the app, I also write the font name and the site it came from, somewhere written smaller under the preview.

3. In a section of the app, I put:

- the whole SIL Open Font License text

- a list of ALL the copyright notices that are found inside the font packager, for instance:

Copyright (c) 2012 by AuthorName, with Reserved Font Names "Font File"

Copyright (c) 2011 by AuthorName2, with Reserved Font Names "Font File2"

Copyright (c) 2014 by AuthorName,3 with Reserved Font Names "Font File3"

Is my usage correct and allowed? Am I doing everything legally correct? Do I need to do anything else? Thank you for your time.

Re: Making sure I do everything right

Hi,

--usually I use Google Fonts (which I understand are SIL)

The Google font library includes many fonts which are licensed under the SIL Open Font License (a license maintained by SIL).

Including the fonts in your package does mean you're bundling them, and it looks like you're planning on doing everything right. You're including the fonts unmodified (with the license text and copyright notices intact inside the font files); the license text display and giving credit is appreciated but not required. If you haven't already seen the OFL-FAQ, that has helpful information (search for bundle).

All the best with your project,
Peter

There would be no embedding or distributing involved, the font would just become part of a JPG or PNG image.
