How to convert TTF to WOFF
- Add your .TTF file - drop it in the box above or click to browse.
- Convert it to .WOFF in a few seconds.
- Download your new .WOFF file.
What to expect
- WOFF wraps the sfnt tables from your TTF without changing outlines, hinting, or kerning - the conversion is lossless and the font renders identically from both formats.
- For new sites prefer WOFF2, which uses Brotli compression and is typically 30-50% smaller than WOFF; keep WOFF only as a fallback for IE 9-11.
- Font licensing carries over to the WOFF file - check the license before publishing, as many fonts are free for personal use only.
Frequently asked questions
Is TTF to WOFF conversion lossless?
Yes - WOFF is a compressed container for the same TrueType data; outlines, hinting, and kerning are unchanged, so the font renders identically.
Should I use WOFF or WOFF2?
WOFF2 is preferable for modern sites because Brotli compression makes it 30-50% smaller; use WOFF only if you need to support IE 9-11.
Can I convert WOFF back to TTF?
Yes - fontTools, Transfonter, and FontForge can all unwrap a WOFF back to TTF; because the conversion is lossless the result is identical to the original.
Do I need to convert each font weight separately?
Yes - each
.ttf file (Regular, Bold, Italic, etc.) must be converted individually and referenced with its own @font-face rule.Programs that convert TTF: FontCreator · Glyphs · Birdfont · FreeFontConverter · Online font converter
