Small, single-purpose tools built on the same font data as the rest of the site. Free to use, no account.
Check a typeface name against thousands of existing fonts and registered trademarks before you release it, or generate name ideas that arrive already checked. A screen, not a legal opinion, and honest about the difference.

Releasing a font and not sure which license fits? Answer up to five plain questions about selling, commercial use, and modifications, and get the license that matches, with the text to put in your download.
Open the picker
PowerPoint and other apps refuse to embed fonts whose fsType permission bits say no. Drop a font in and this tool reads the bits and rewrites them, entirely in your browser: your font is never uploaded anywhere.
Open the fixer
Most fonts carry thousands of characters a project never uses. Drop a font in, pick the characters to keep by set, by pasted text, or from a grid of its own glyphs, and download the subset as TTF, OTF, or WOFF2, again entirely in your browser.
Open the subsetter
Drop in a family's font files and get the whole webfont kit: WOFF2 and WOFF conversions, @font-face CSS read from the fonts themselves rather than their filenames, an embedding-permission check, a demo page and notes, built entirely in your browser.
Open the generator
Convert fonts between TTF, OTF, WOFF and WOFF2: a whole family in one pass, each file or a single zip, with no upload and no account. The one job it declines, redrawing TrueType outlines as CFF or back, it declines out loud, with the reason.
Open the converter
View your installed fonts online, in your browser: every family and style on your machine, with live specimens drawn from the real font data. The browser asks your permission first, and nothing is uploaded.
Open the local font browser
Pixels, inches, centimeters, millimeters and points, converted pair by pair: px to inches, inches to px, pt to px and every other combination, each with its formula, table and print-DPI handling.
Open the unit converter
Identify a font from a picture of it. The index is built from measured glyph data across the whole collection, not from names and tags. In development.
In developmentReference, rather than a tool: the font.io freeware licenses, two one-page licenses any designer can adopt, and the articles that explain how fonts work.
Play, rather than work: the font games, scored from the same measurements as everything else here.
