OFL

The Open Font License (OFL) is a free, open license designed specifically for font software and font data. It is published by SIL International and is used to govern the distribution and use of fonts, including font files and related sources. The OFL aims to allow broad use of fonts in software, documents, websites, and other works while protecting the rights of the font designers.

Under the OFL, users are allowed to use, study, modify, and redistributes the font and its derivatives. Fonts released under the OFL can be used in commercial and noncommercial projects, and they may be embedded in documents, software, or other products. It is common for the license to permit redistribution as part of larger works, including commercial ones, as long as the terms of the OFL are followed.

The license imposes several conditions. Redistributions must include the OFL text and the font’s copyright notices. If you modify the font and distribute the modified version, you must do so under the OFL as well. The OFL also contains a Reserved Font Name clause, which restricts the use of the original font name for modified versions unless the license allows it. Additionally, you may not sell the font by itself; it must be distributed as part of a larger product or under terms that preserve the OFL.

The OFL is widely used in the font community for open fonts and is designed to be compatible with other open-source licenses. It is commonly found in fonts used on the web and in desktop environments. For the exact terms and conditions, the official OFL text provided by SIL should be consulted.
