How to convert fonts

Use this tool when you need web fonts (WOFF/WOFF2) from desktop fonts, or when you need to unpack a web font back to TTF/OTF.

Drop or select one or more .ttf, .otf, .woff, or .woff2 files.
Choose WOFF2, WOFF, or TTF/OTF as the output format (and WOFF2 quality if needed).
Click Convert — processing runs entirely in your browser.
Download each file or grab a ZIP of all results.

Fonts are converted locally. Nothing is uploaded to a server.

Frequently Asked Questions

What does this font converter do?

It converts between common font containers: TTF/OTF (SFNT) and the web formats WOFF and WOFF2, including batch conversion.

Which formats are supported?

Inputs: TTF, OTF, WOFF, WOFF2. Outputs: WOFF2, WOFF, or the original SFNT saved as .ttf or .otf depending on the font flavor.

Can I convert OTF outlines to TTF (or the reverse)?

No. This tool changes the container (WOFF wrapping), not the glyph outline format. CFF (OTF) stays CFF; TrueType stays TrueType when you choose TTF/OTF output.

Are my fonts uploaded?

No. Conversion runs in your browser with woff-lib. Files stay on your device.

What is WOFF2 quality?

It controls Brotli compression level from 0 (fastest) to 11 (smallest). Higher values take longer but usually produce smaller WOFF2 files.
