Font Viewer & Inspector
Inspect TTF, OTF, WOFF and WOFF2 fonts: glyph grid, metrics, name table, OpenType features and a live type tester.
Free, no uploads, no sign-up. Runs 100% in your browser.
How Font Viewer & Inspector works
The font is parsed with opentype.js to list every glyph, its outline, metrics and the name table. The type tester uses the browser's own font engine with font-feature-settings, so OpenType features render exactly as on a website.
Input: TTF, OTF, WOFF, WOFF2. Output: SVG.
How to use Font Viewer & Inspector
- Drop a font file.
- Type your own text in the tester and change size and spacing.
- Browse or search the glyphs and click one for details.
- Turn OpenType features on and off.
Tips
- Search glyphs by character, name or code point such as u+00e9.
- Save any glyph as an SVG for icons or logos.
Font Viewer & Inspector FAQ
- Is my file uploaded?
- No. Everything runs in this browser tab on your own device. Engines are downloaded once and cached, but your files never leave your computer.
- Are my files uploaded?
- No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.
- Is it free? Are there limits or watermarks?
- Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.
- Does it work offline?
- Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
