About Converting TTF to WOFF
WOFF (Web Open Font Format) was the first standardised web font wrapper, applying zlib compression to TrueType/OpenType data and adding metadata fields. While WOFF2 is now smaller and preferred, WOFF remains valuable as a fallback format because it is supported by a slightly wider range of older browsers, including legacy versions that predate WOFF2.
PrivConvert wraps your TTF in the WOFF container, compressing it while leaving the glyph outlines and hinting untouched. The conversion is performed in memory and your file is purged the moment it completes.
Common use cases
- Providing a WOFF fallback alongside WOFF2 for maximum browser coverage
- Supporting older browser versions that do not understand WOFF2
- Self-hosting a web font on a site that targets legacy environments
- Converting a desktop TTF into a compressed, web-ready container
- Building a layered @font-face stack for broad device support
Tips for best results
- List WOFF2 first and WOFF second in your @font-face src so modern browsers pick the smaller file.
- If you do not need legacy support, WOFF2 alone is enough and lighter — skip WOFF entirely.
- WOFF preserves all the original font metadata, so licensing and naming fields stay intact.
- Subset the font to the glyphs you actually use to reduce download weight.

A more private way to convert TTF files
Plenty of sites convert TTF files. Very few promise never to keep them — PrivConvert does, and backs it up with how the service is built.
Convert instantly with no sign-up, no email and no profiling cookies. We never build a profile around you or the files you convert.
Runs in any modern browser on Windows, macOS, Linux, Android and iOS — no install, plugin or desktop software needed.
Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.
We never keep a copy. Once your WOFF is delivered, both the original and the result are gone — there is nothing left to leak or misuse.
