How to Convert OTF or TTF to WOFF2
Desktop font files are not what most websites should ship directly. A web project usually needs WOFF or WOFF2 so the font loads faster and behaves more predictably in browsers.
Know the file types
- OTF and TTF are desktop-oriented source formats.
- WOFF is a webfont format with broad support.
- WOFF2 is usually the preferred modern output because it is smaller.
Basic workflow
- Start with the original `.otf` or `.ttf` file.
- Convert it to `WOFF2` for modern websites.
- If you need a fallback, also export `WOFF`.
- Reference the webfont in your CSS rather than uploading the desktop font file directly.
What to watch for
Not every font license allows web embedding. Conversion only changes the format, not the licensing rights. Also, if a browser build cannot produce `WOFF2`, export `WOFF` as a fallback and continue from there.
What developers actually need
In many real projects, the useful end state is not just “I have a converted file.” It is “I have the right file format and know what to use in production.” That usually means WOFF2 first, WOFF second, and clear CSS references in your stylesheet.
Use the tool
Convert your desktop font in Font to Webfont and export WOFF or WOFF2 for the web.

Before you ship webfonts
A font file can convert successfully and still be wrong for a website if the license, character coverage, weight selection, or CSS loading strategy is not ready. Test headings, body copy, numbers, and accented characters before publishing.
Treat conversion as one part of the webfont job. The final setup also needs correct file paths, fallback fonts, caching, and a font-display choice that matches the site. If the font is only used for headings, avoid shipping unnecessary weights that slow down every page.
- Confirm the license allows web use.
- Ship only the weights and styles the site needs.
- Use CSS with sensible fallback fonts and a clear font-display choice.
After downloading the result, open it once before using it in a client send, upload form, website, or archive. This final check catches format support issues, unexpected file size changes, missing characters, clipped media, or page-order mistakes while the original file is still available.
If the output will be reused, note the settings that produced it. That makes the next export easier to repeat and reduces guesswork when another file needs the same treatment.
