Convert TTF files to WOFF free in your browser — no signup, no install, and the file is never uploaded to a server. WOFF keeps full quality with no further loss.
Add your TTF file
Drag the TTF file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm WOFF as the output
WOFF is already selected as the output format on this page. This format converts straight through with no extra settings.
Run the conversion
Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.
Download the WOFF file
When it finishes, download the WOFF file. Converting multiple files gives you the option to download them together as a ZIP.
A font format jointly developed by Apple and Microsoft and supported natively by every operating system. It carries hinting data that keeps text crisp at small sizes.
A font format compressed specifically for websites. It wraps TTF or OTF data to cut transfer size, which speeds up page loading.
Yes. TTF to WOFF conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the TTF file never leaves your device. That is also why it works without an internet connection once the page has loaded.
It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
