Font Studio — Font Subsetter
Ship the characters you use. Drop the thousands you don't.
Your app or website ships a font containing thousands of glyphs it never renders. Every unused glyph is a kilobyte your users download for nothing.
Capabilities
What it does
- Keep only the characters your project uses
- Range presets for twelve common Unicode ranges
- Custom characters field for exact keep-lists
- Composite glyphs keep their component glyphs automatically
- Result report: glyphs kept, characters matched, size saved
- Split large fonts per script or range

Workflow
How it works
- 01
Collect the characters your project really renders — real strings, digits, punctuation, symbols users might type.
- 02
Open Subset Font and pick range presets, paste custom characters, and watch the live counter.
- 03
Run the subset — the result screen reports glyphs kept, characters matched and bytes saved.
- 04
Validate the subset and export it — the original stays untouched.
