Convert TTF to WOFF2
Turn your TTF into a WOFF2. WOFF2 is the usual choice for the primary @font-face source on any modern website. Your file never leaves your computer.

How to convert TTF to WOFF2
- 1 Drop your TTF .ttf file onto the page, or click to browse for it.
- 2 Check the options. Nothing is thrown away on the way to WOFF2, so there is no quality dial to set.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the WOFF2, or add more files and do the whole set in one go.
Why convert TTF to WOFF2
- The smallest widely supported font format, around half the size of TTF.
- Supported by every browser in current use, so no fallback is needed.
- Self-hosted font packages such as the Fontsource npm distributions.
- TTF: uncompressed, so files are several times the size of the same font as WOFF2.
TTF compared with WOFF2
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | TTF | WOFF2 |
|---|---|---|
| File extension | .ttf | .woff2 |
| Compression | Uncompressed | Lossless |
| Colour depth | Quadratic outlines with TrueType hinting bytecode | Brotli compression with a transformed glyf table |
| Typical file size | Largest | Larger |
| Introduced | 1991 | 2018 |
| Developed by | Apple and Microsoft | Google, standardised by W3C |
Quality and what changes
Both sides are lossless, so every pixel survives the trip intact and converting back returns the same image. What changes is the size and what the file can carry: WOFF2 compresses the same data with a different algorithm, so the size can move in either direction.
- One WOFF2 limitation to keep in mind: takes longer to produce than a WOFF.
Questions about TTF to WOFF2
Is my TTF file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your TTF is read straight from your own disk, converted on your machine and handed back as a WOFF2. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several TTF files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate WOFF2 downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
