Webfont Converter

Convert font files between multiple formats including TTF, OTF, WOFF, and WOFF2. High-quality conversion with optimized compression, all processed in your browser.

Overview

This webfont converter lets you convert font files between TTF, OTF, WOFF, and WOFF2 formats without uploading anything to a server. All conversion runs directly in your browser using WebAssembly, so your typefaces — including licensed or proprietary fonts — stay entirely on your device. Batch-convert multiple font files at once, then download the results ready to drop into your CSS. No account, no queue, no waiting.

Common Use Cases

  • Prep fonts for the web — Front-end developers convert TTF or OTF desktop fonts to WOFF2 to serve smaller, browser-optimized webfont files.
  • Shrink existing webfonts — Designers re-encode legacy WOFF files to WOFF2 to cut file size by roughly 30% and improve page load performance.
  • Ensure broad browser support — Teams generate both WOFF and WOFF2 from a single source font to cover all browsers with a two-format @font-face stack.
  • Protect proprietary typefaces — Studios working with licensed fonts convert them locally so the font files are never transmitted to a third-party server.
  • Batch-convert a full type family — Developers drop an entire multi-weight font family and convert all variants to the target format in one pass.
