Your Fonts Never Leave Your Browser

Font Converter

Every online font converter asks you to upload your files. Your licensed fonts, sent to a server you’ve never audited. Where? For how long? Under what terms?

Font Converter runs Google’s own WOFF2 codec inside your browser. Zero bytes uploaded. Zero servers contacted.

OTF to WOFF2. WOFF2 to TTF. Google's own codec. Zero uploads.

The Problem With Every
Other Font Converter

CloudConvert. Convertio. Font Squirrel. They all work the same way: upload, wait, download.
  • Your fonts leave your machine → Licensed fonts have usage terms. Some explicitly prohibit uploading to third-party services. Every online converter breaks this.
  • One file at a time → Got a font family with 12 weights? That's 12 uploads. 12 waits. 12 downloads. Rename each file. Try not to lose track.
  • Needs internet → On a plane. In a cafe with terrible WiFi. On a client's locked-down network. No connection, no conversion.
Font Converter has none of these problems. Because it doesn't use a server. One of the font conversion tools that runs entirely client-side.

Drag a Folder.

Get a ZIP.

Drop your entire fonts directory. Every OTF and TTF inside converts. Nested folders included.
  • Compress (OTF/TTF WOFF2) → Drop your font files or an entire folder. Google's WOFF2 codec converts each one. Download individually or as a ZIP.
  • Decompress (WOFF2 TTF) → Switch to Decompress mode. Drop your .woff2 files. Get standard .ttf files back for desktop editing.
  • Batch export
  • Lossless
  • Every font on your site that isn’t WOFF2 is costing you ranking points.
No settings to configure. No quality sliders. WOFF2 compression is deterministic — same input always produces the same output.
