Glyph Viewer — Inspect Font Characters

See every character inside a font

A font file is a small database of glyphs, metrics and names. This glyph viewer opens that database in your browser and shows everything at a glance. The metadata panel lists the family and style names, full name, version string, designer, manufacturer, license text and license URL, the number of glyphs, the units-per-em grid, the ascender and descender and whether the outlines are TrueType or CFF (PostScript). It is a quick way to confirm which weight a file really contains or whether a font from an old project covers the languages you need.

Below the metadata, a paged grid draws 60 glyphs at a time, labelled with their Unicode code point or, for unencoded alternates, their glyph index. Click a glyph or move through the grid with the arrow keys to open it in the detail view, which draws the outline with baseline, ascender, descender and advance width guides and lists its name, code points, left side bearing and bounding box. The search box jumps straight to a character, a code point such as U+00E9 or a glyph index such as #42.

Check coverage and test real text

Before choosing a typeface for a multilingual site or app, check that it contains every letter you need. Search for the special characters of each language — for example ł, ő, ș or ї — and the viewer tells you immediately whether they exist. The type-to-preview area renders your own sentence with the font's kerning at any size from 12 to 160 pixels, so you can judge spacing and rhythm before installing anything.

All parsing is done by opentype.js, and WOFF2 files are unpacked with a WebAssembly decoder, so the font never leaves your computer. That makes the tool safe for commercial and unreleased fonts. Keep in mind that looking at a font is always fine, but using it in a project still requires a license that covers that use — the license field in the metadata is a good place to start.
