Sharing a typeface is a quick and easy process, but you need to prepare a few things first:

1. Register an account, and log in
2. Make sure you have the font files and the source files
3. Write a short description, and a fontlog, giving a summary of the typeface’s history
4. Create an attractive sample image to show off your typeface in use (PNG or JPEG)
5. Decide on the license you want to use for the font files

Font files that you upload to the Open Font Library will immediately be available for everyone to use. When you choose the license, you are declaring that the font files only contain things that

• you hold the copyright for (usually because you designed them), or
• are licensed to you under a free software license, such as the Open Font License.

The Open Font Library stores your uploaded files in a typeface record. The typeface record keeps related font files together for ease of reference. For example, it could contain the regular, bold and italic variants, or it could contain a regular and a distorted variant. To give visitors easy access, it is best to add all the variants into one typeface family record.

You can also add the license to each font file itself easily with FontForge. We recommend including as much font metadata inside your font files as possible.
