Licenses explained

Usually, the fonts featured here on FontsArena have licenses like “Free for personal use” or “Free for both personal and commercial use”, which are pretty self-explanatory.

However, some fonts will have licenses like “SIL OpenFont License 1.1” or “Apache License, version 2.0” and that may seem confusing. Sometimes even reading the license doesn’t help, as the language and formulation is typical for legal documents rather than clear and understandable.

So what do those licenses mean? Can I use the fonts commercially? Or for web? Or embed in my app or ebook? These are just a few questions that this article attempts to answer.

  1. SIL OpenFont License

    Abbreviated as OFL or SIL OFL, it’s specified on FontsArena as SIL OpenFont License 1.1
    See the license’s official webpage

    It’s the most common sight when it comes to “mysterious” licenses for free fonts. For example, it covers almost all the fonts in the Google Fonts Directory (see Google Fonts licenses).

    SIL OpenFont is a free software license, and fonts covered by this license can be freely used, modified, and distributed (as long as the derivatives remain under the same license).

    Please note that the copyright holder has the option of declaring the font’s name as being a “Reserved Font Name“, which means that any modified versions of the font must be renamed so that they don’t contain the original name. Subsetting for web fonts are also considered modified font.
