WOFF → TTF / OTF
Convert legacy WOFF webfonts back to raw TTF or OTF. Uses the browser's built-in decompression — no server, no upload.
Runs entirely in your browser — no upload, no registration.
What this tool does
Parses the WOFF header, deflate-decompresses each table with the browser's DecompressionStream API, then re-composes a valid SFNT (TTF or OTF).
Why you might need it
WOFF is the older webfont format — useful when you need the original font for desktop install or further conversion to WOFF2.
How to use it
- Drop a .woff file.
- Download the resulting TTF/OTF.
Supported formats
- Input: .woff (zlib-compressed SFNT).
- Output: .ttf or .otf depending on outlines.
Limitations
- WOFF 1.0 only. For WOFF2 use the dedicated WOFF2 → TTF tool.
Always review the included licence before commercial use. Do not remove copyright records, designer names, licensing metadata or embedding restrictions from any font you process.
