OpenType Feature Viewer
Not every 'fancy' feature ships in every font. Drop a file to see exactly which OpenType features it supports — small caps, tabular numbers, stylistic sets and more.
Runs entirely in your browser — no upload, no registration.
What this tool does
Reads the GSUB and GPOS tables and lists every feature tag registered inside.
Why you might need it
Fonts that advertise 'small caps' don't always ship the smcp feature. Verify before you rely on it.
How to use it
- Drop a font.
- Read the feature list.
- Pair with our font-feature-settings generator to actually use them in CSS.
Supported formats
- Input: TTF, OTF, WOFF.
Always review the included licence before commercial use. Do not remove copyright records, designer names, licensing metadata or embedding restrictions from any font you process.
