How to convert TTF to WOFF

- Download. Each file appears in the list when it is ready. Download them one by one, or all together with Download all.
Why convert TTF to WOFF?
WOFF is the compressed web font format that every browser supports, including some older ones that do not support WOFF2. Converting TTF to WOFF makes your font load faster on a website.
When to keep the TTF
Keep the TTF for installing the font on computers and using it in design software.
Tips for the best result
- The letter shapes are not changed; the font data is only compressed.
- For current browsers WOFF2 is smaller still; WOFF is a good fallback.
- Check that the font licence allows web use.
Common problems and fixes
- The font does not show on my site.
- Check the path in your @font-face rule, and that your server sends the file. Fonts from another domain need CORS headers.
- The file will not convert.
- Font collections (TTC) are not supported. Use a single TTF file.
WOFF – Web Open Font Format
WOFF is a compressed font wrapper designed for websites. It is supported by every current browser and loads faster than raw TTF or OTF files.

- Wraps or unwraps fonts; outlines are not changed, so a WOFF unwraps to the TTF or OTF it was made from.
Frequently asked questions
WOFF or WOFF2?
WOFF2 is smaller and supported by all current browsers. Use WOFF only as a fallback for older browsers.
Does it change the font?
No. The outlines and features are identical.
How do I convert TTF to WOFF?
Click Select File or drop your TTF file onto the upload box. The converted WOFF appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
