Font Studio — Font Health
Know a font is healthy before your users find out.
The font renders fine on your machine — but "fine on my machine" is not validation. A structural scan tells you what an installer or renderer will think of it.

Workflow
How it works
- 01
Open the font and run the scan — Full covers per-glyph geometry; Quick skips the expensive checks.
- 02
Read the score band and the plain-language summary: polishing, or rescuing.
- 03
Drill into findings — each names affected tables and glyphs, and whether a fix exists.
- 04
Jump to repairs, or export with confidence if the scan is clean.
