OutputA4 specimen
Load a local TTF or OTF, test real copy at multiple sizes, inspect Unicode glyph coverage, and export a rendered specimen sheet.
Step by step
01Start with the source
Choose a single-face TTF or OTF font from your device. The editor loads it through the browser FontFace API and reads its Unicode character map locally. Without an upload, the sample uses system Arial and reports coverage as unknown.
02Edit and inspect
Enter real copy, select a body size and line height, and inspect the size waterfall. Browse Latin, Greek, or Cyrillic sample blocks. Missing requested characters are identified from the uploaded font’s character map rather than from browser fallback rendering.
03Export and verify
Download the specimen as PNG or PDF. The export captures rendered text so the recipient does not need to install the font. Check the actual words and scripts you intend to use; a character-map entry alone cannot establish shaping quality.
Why this one
Fallback can hide a missing glyph
A browser may display a character using another installed font when the selected face lacks it. The glyph checker reads Unicode cmap format 4 or 12 directly, so a visible fallback character is still correctly reported missing from the uploaded face.
Coverage is narrower than language support
A cmap entry maps a code point to a glyph. It does not verify ligatures, combining-mark positioning, script shaping, variation selectors, or typographic suitability. Test complete words and paragraphs in addition to looking at individual character cells.
The specimen travels as artwork
PNG and PDF capture the rendered specimen instead of assuming the reader has your font installed. Source font files remain in browser memory and are removed from the document font set when replaced. WOFF, WOFF2, and font collections are outside this editor’s supported formats.
FAQ
The font specimen editor loads a local TTF or OTF into the current browser document without installing it in the operating system.
The font specimen editor reads the uploaded font’s Unicode cmap mappings and checks requested non-whitespace code points against them.
The font specimen editor supports single-face TTF and OTF files, not WOFF, WOFF2, or font collections.
The font specimen editor checks code-point mappings. It does not establish correct script shaping, ligatures, or combining-mark placement.
