Sphinx of black quartz, judge my vow.
Loaded font
System sans-serif
Searchable glyph map
Browse Unicode characters mapped by the font. Search a character or a code point such as
U+0041, then open a tile for its glyph outline and metrics.
No mapped character matches that search.
Font details & coverage
Read the data included in this file. Metadata can be incomplete; embedding flags are technical hints and do not replace the font's legal license.
Unicode coverage
OpenType features
Font tables
Copy-ready @font-face CSS
Use this as a starting point after placing the font at the shown path. Confirm that the license permits web embedding before publishing.
Three fast steps
Preview a WOFF2 file without installing it
The browser does the work locally, so even licensed project fonts can be checked without sending the file to a conversion service.
Test real content
Type the headline, UI label, number, or paragraph you actually need to evaluate.
Inspect before shipping
Check axes, glyph coverage, metadata, OpenType features, and the generated CSS starter.
More than a pangram
See what is actually inside your WOFF2 font
A useful preview answers visual and technical questions in the same place. These checks help prevent missing characters, wrong font files, and weak production CSS.
Live typography controls
Test custom text at the exact size, line height, spacing, alignment, and colors your design needs.
Searchable glyph map
Find mapped characters by glyph or Unicode code point and open individual outlines and metrics.
Real variable font axes
Adjust every axis declared by the font, including weight, width, optical size, slant, and custom axes.
Metadata and CSS handoff
Review names, version, metrics, features, embedding flags, and a practical `@font-face` snippet.
Local by architecture
Your font file never leaves the browser
`FontFace` renders the file and Fontkit reads its tables in browser memory. There is no font upload endpoint, no account, and no server-side copy to delete later.
- Safe for confidential reviewFont bytes and preview text are never sent to us.
- No file name in analyticsOnly coarse interactions and generic file-format buckets may be measured.
- Automatic cleanupReload or close the page and the in-memory font is gone.
Format guide
WOFF2 compared with WOFF, OTF, and TTF
WOFF2 is a compressed webfont container, not a separate drawing model. It can carry TrueType or OpenType outlines, variable fonts, color fonts, and other OpenType data supported by the browser.
| Format | Best use | Compression | Browser delivery | This tool |
|---|---|---|---|---|
| WOFF2 | Modern production web fonts | Strong Brotli-based compression | Preferred for current browsers | Full preview & inspection |
| WOFF | Legacy webfont fallback | Older compression | Broad older-browser support | Preview & inspection |
| OTF | Desktop/source font workflows | Usually not web-compressed | Supported, but WOFF2 is leaner | Preview & inspection |
| TTF | Desktop/source font workflows | Usually not web-compressed | Supported, but often larger | Preview & inspection |
Practical answers
WOFF2 font preview FAQ
How do I preview a WOFF2 font file?
Drop the file into the picker or choose it from your device. The live preview appears immediately; then type your own text and adjust the typography controls.
Does this WOFF2 viewer upload my font?
No. Font bytes are loaded, rendered, and parsed in your browser memory. They are not sent to our server, stored, or included in analytics.
Can I preview a variable WOFF2 font?
Yes. If the file declares axes such as `wght`, `wdth`, `opsz`, or `slnt`, the preview creates one slider per axis and applies changes live.
Which font formats are supported?
The tool is designed around WOFF2 and also accepts WOFF, OTF, and TTF files. Final rendering still depends on the font data your current browser supports.
Can I inspect every glyph?
You can browse characters mapped in the font's Unicode cmap, search by character or code point, and open details for the mapped glyph. Some internal or substitution-only glyphs have no direct Unicode mapping and may not appear in the character grid.
Why does the font fail to load?
The file may be corrupt, mislabeled, unsupported by your browser, or larger than the 25 MB safety limit. Confirm the extension, try a current browser, and validate the original font with your font editor.
Can I use the generated CSS on my website?
Yes, as a starting point. Put the font at the referenced path, adjust the family and styles, and verify that your license permits web embedding. Technical embedding flags are not legal advice.
