Font Subset Generator

Strip unused glyphs from a font file to generate a tiny .woff2 for your site. Upload a font or scan live pages for detected fonts and on-page text, then combine a character list with optional Unicode presets.

Font file

Upload a file or scan pages for text and font files.

Option 1: Upload font file

Drop a font file here, or browse

.ttf, .otf, .woff, .woff2 — max 15 MB

Option 2: Scan pages for text + fonts

What scan does

Crawls each URL for visible page text and CSS font files, then fills your character list and detected fonts for quick selection.

Characters to keep

Preset ranges combine with the textarea. Each scan replaces the textarea with sorted, unique characters from those pages.

Duplicates are removed when you generate.

Unicode presets

Add whole ranges on top of the textarea. Presets and manual text are merged into one subset.
