# Font tools.

> Convert, subset and instance fonts — all on your device.

Font work usually means a Python toolchain or a paid app for what is, at heart, one transform: get this typeface into the format and size the web wants. These pages run HarfBuzz and Brotli **locally in your browser** — TTF and OTF to WOFF2 and back, character-set subsetting, and static instances cut from variable fonts.

**No uploads · No ads · Free & open source.**

## How it works

1. Pick a direction — convert between formats, subset, or instance.
2. Drop the font; HarfBuzz and Brotli process it locally.
3. Download web-ready files — licensing stays your responsibility.

## Frequently asked questions

### Which format should web fonts use?

WOFF2, full stop — Brotli compression makes it the smallest, and every browser that matters supports it. The converters exist mostly to get things INTO woff2, and back out when a desktop app needs TTF.

### What does subsetting actually do?

It keeps only the glyphs you name — a Latin-only subset of a big multilingual font routinely drops 70–90% of the bytes. The subsetter page previews exactly which characters survive.

### What about variable fonts?

Two options: convert them as they are, or use the instancer to freeze one weight/width combination into a small static font — the right pick when you only use Regular and Bold.

### Am I allowed to convert this font?

That depends on its license, not on the tool — conversion happens on your device, but a font’s EULA may restrict web embedding or modification. Check it; open-license fonts (OFL) are safe.
