Webfont Converter

Overview

Convert fonts between TTF, OTF, WOFF and WOFF2. Drop in a single file or a whole family, pick the format, and download the results ready for your CSS. The conversion runs in your browser with WebAssembly, so licensed and in-house fonts never leave your computer.

Shrink old webfontsRe-encode WOFF files as WOFF2 to cut their size by about 30%.

Keep licensed fonts privateConvert licensed fonts locally, so the files never go to a third-party server.

Frequently asked

What font formats are supported for conversion?

TTF, OTF, WOFF and WOFF2, in any direction.

Is there a file size limit for font conversion?

Yes, 50 MB per font file. That covers almost every font.

Are my font files uploaded to your servers?

No. Fonts are converted in your browser and never leave your computer.

Can I convert multiple font files at once?

Yes. Drop in several files, a whole family if you like, and convert them in one go.

What's the difference between WOFF and WOFF2?

WOFF2 compresses better, usually about 30% smaller than WOFF, and every modern browser supports it. WOFF is older and works in a few more places.

Will font conversion affect the quality or appearance?

No. Glyphs and character mappings stay the same, so the font looks identical. The only exception is when you choose a smaller character set yourself.
