Font Studio — Font Editor
Edit any TTF or OTF font. On your device.
You need to change a font file — swap a glyph, fix spacing, rename the family — but desktop font editors are expensive and online tools want your file uploaded to a server.
Capabilities
What it does
- Open TTF, OTF and WOFF fonts in a full editing workspace
- Remove, add and replace glyphs
- Edit spacing, advance widths and kerning pairs
- Inspect metadata, metrics and Unicode coverage before you edit
- Undo history — the original file is never overwritten
- Export to TTF, OTF or WOFF

Workflow
How it works
- 01
Open the font — TTF, OTF or WOFF — and inspect what you have: metadata, character coverage and structural health.
- 02
Make your edits: glyphs, metrics, names or character set. Every tool applies its result as an undoable project step.
- 03
Validate the edited font with Font Health before you ship it anywhere.
- 04
Export the modified file — the original stays intact.
Who it's for
Made for this job
- Designers and developers who need one surgical edit, not a desktop font suite
- Anyone who prefers their font files not to be uploaded to a web converter
