WOFF to OTF Converter

Converting WOFF to OTF unwraps the compressed web font to produce a standard desktop OpenType file. The extracted OTF preserves every glyph, OpenType feature, and outline from the original. Useful for installing a web font on your desktop or feeding it into professional typography workflows.

What changes when you convert WOFF to OTF

Lossless extraction. If the WOFF wrapped an OTF, the output is bit-identical after decompression. If the WOFF wrapped a TTF, the resulting OTF contains TrueType outlines rather than CFF. Still valid OpenType, just not using OTF's full PostScript-outline capability.

When to use this conversion

  • Installing a web font on your desktop for design work in InDesign, Illustrator, or Affinity
  • Extracting a web font for use in a print workflow that expects OTF
  • Integrating web-delivered fonts into a professional typography pipeline
  • Archiving web fonts in a format that preserves advanced OpenType features cleanly

Where the output works

OTF runs in every modern OS, every major design and DTP application, and every current browser.

About these formats

WOFF (Web Open Font Format)

WOFF (Web Open Font Format) is a 2010 wrapper that zlib-compresses a TTF or OTF for web delivery. Files are roughly 40% smaller than raw TTF/OTF, with the same glyph data preserved exactly. WOFF works in every browser back to IE9 and exists primarily for the web.

OTF (OpenType Font)

OTF (OpenType) is Microsoft and Adobe's extension of the TrueType format. It adds cubic Bézier (PostScript/CFF) glyph support plus rich typographic features: stylistic alternates, ligatures, small caps, contextual substitutions, and the full OpenType feature model. Professional typography depends on OTF's capabilities.

How It Works

  1. Add your WOFF files Drag WOFF fonts onto the page, or click to pick them from your file browser. Batch uploads are fine.
  2. Convert to OTF The converter reads the WOFF tables and rewraps them in OTF form with appropriate compression.
  3. Runs in your browser Everything happens locally via WebAssembly. Nothing uploads. Font files stay on your device.
  4. Download OTF files Grab each converted file individually, or download the whole batch as a single ZIP.

FAQ

Will OpenType features survive?

Yes, completely. The WOFF wrapped the font's OpenType tables without modification; extraction preserves them exactly.

Is this always lossless?

Yes. WOFF is a lossless compression container. Decompressing it produces exactly the font data that was compressed into it.

Are my files private?

Yes. The converter runs entirely in your browser using WebAssembly. Your font files are never uploaded, never sent to a server, and never leave your device.

Is there a file size limit?

There's no hard limit. Font files are usually small (under a few MB), so even very large fonts process without issue. Variable fonts with many axes are handled cleanly.
