Free font converter. Keep the font.

Refont converts TTF, OTF, WOFF and WOFF2 fonts in your browser. Kerning, OpenType features and every curve are carried across, and your fonts are never uploaded.

Features

A converter that tells you what it did

Refont rebuilds the font and shows you exactly what changed, file by file.

Nothing is uploaded

Every conversion runs inside your browser tab. Nothing about your font is sent anywhere, and you can check this in your browser's network tab.

Real outline conversion

OTF to TTF rebuilds the curves instead of renaming the file, so the shapes stay within one font unit and the kerning is kept.

A report for every file

Each converted font comes with a report: glyph count, kerning, OpenType features and variable axes, so you can see what was kept and what changed.

A license check

Refont reads the font's embedding settings and shows a warning in the report when the font is restricted, so you can check your license before using the result.

No size limit

Large fonts are fine. There is no file size limit, no account and no watermark.

Offline once loaded

The converters are WebAssembly builds of Google's WOFF2 library and fontTools. Each one loads the first time you need it, and after that keeps working without a connection.

FAQ

Common questions

Is Refont free?
Yes. It is free, with no account, no file size limit and no watermark.
Are my fonts uploaded?
No. Every conversion runs inside your browser tab and nothing about your font is sent anywhere. Each converter loads the first time you use it, and after that it keeps working offline.
Which formats can it read and write?
It reads TTF, OTF, WOFF, WOFF2, TTC, dfont, EOT, Type 1 (PFB) and ZIP archives of those, and writes OTF, TTF, WOFF2 and WOFF.
Is it legal to convert any font?
That depends on the font's license, not on the tool. Refont's license check reads the font's embedding settings and warns you when a font is restricted, but you are responsible for having the right to convert it.
Why is OTF to TTF slower the first time?
Real outline conversion uses fontTools, which is about 7.5 MB and has to load into your browser first. After that it is quick.
Where do I use Refont?
At refont.app. It runs in a current web browser, with nothing to install and no account.
