Convert, subset and preview fonts in your browser
Convert TTF, OTF, WOFF and WOFF2 fonts, subset glyphs, inspect characters and turn text into SVG paths — all locally in your browser. Your font files never leave your device.
Font Converter
Convert TTF, OTF, WOFF, WOFF2, EOT and SVG fonts in batches and get a ready @font-face CSS rule.
Font Subsetter
Shrink fonts to only the characters you need with HarfBuzz and export TTF, WOFF or WOFF2.
Glyph Viewer
Open a font to browse every glyph, read its metadata and metrics and preview your own text.
Text to SVG Path
Turn text into SVG outline paths with any font — set size, spacing and alignment, copy or download.
Free font tools that never upload your files
Font Tools is a small set of utilities for designers and web developers who work with font files every day. The font converter turns TTF and OTF fonts into compressed WOFF2 and WOFF files for the web, unpacks WOFF2 back into installable TTF, and can still produce EOT and SVG fonts for legacy projects. It converts whole batches at once and writes a ready-to-paste @font-face rule. The font subsetter uses HarfBuzz, the engine behind Google Fonts, to strip every glyph you do not need, often shrinking a font by 80–95% and speeding up your pages.
To look inside a font, open it in the glyph viewer: it lists names, version, designer, license and vertical metrics, draws every glyph in a paged grid, shows the details of each character and lets you type your own preview text. The text to SVG path converter turns words set in any font into clean vector outlines that you can copy into code, use as a logo or send to a laser cutter or plotter.
Font formats and licensing in a nutshell
TTF and OTF are the desktop formats you install on a computer; OTF files usually contain PostScript (CFF) outlines, TTF files TrueType outlines. WOFF and WOFF2 are compressed wrappers made for browsers, and WOFF2 is the only format most modern websites need. EOT and SVG fonts belong to the era of Internet Explorer and early iPhones. Every tool here runs entirely in your browser with JavaScript and WebAssembly, so your fonts — including commercial and unreleased typefaces — never leave your device.
A technical tool cannot tell you what a font's license allows. Converting, subsetting or embedding a font on a website may require a web license, and some licenses forbid modifying the font at all. Fonts under the SIL Open Font License or Apache License can usually be converted and subset freely. When in doubt, check the license text shown in the glyph viewer or ask the foundry before publishing.
