Font to webfont guide
Use this tool when you already have a licensed desktop font file and need a smaller webfont format for a website, landing page, or design system.
How it works
The browser reads the source font, converts it with the client-side font engine, then downloads the converted webfont file.
Supported files
Input supports TTF and OTF. Output supports WOFF and WOFF2. Variable fonts, unusual tables, or damaged files may not convert cleanly.
Privacy and limits
The font is processed in this browser session. You are still responsible for checking that your font license allows web embedding.
Common issues
- WOFF2 is usually smaller, but WOFF can be useful for broader compatibility needs.
- Conversion does not automatically create font subsets or remove unused glyphs.
- If the converted font renders oddly, test the original font and try the other output format.
Next step
Preview the result with Font Preview, then generate a ready-to-paste block with Font CSS Generator.
Example webfont conversion jobs
Marketing page font: confirm the license allows web use, convert the needed weight to WOFF2, then generate CSS after the filename is final.
Legacy browser fallback: export WOFF2 first and WOFF only when the project support list requires it.
Design review: preview headings, numbers, and brand words before publishing the converted font to a live site.
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.
