When to Convert
Common scenarios where this conversion is useful
Using a web font in Adobe Creative Suite
InDesign, Illustrator, and Photoshop need OTF or TTF fonts. Convert your WOFF files to OTF to use them in print design, vector illustration, and image editing projects.
Installing a web font for system-wide use
OTF fonts can be installed on any operating system. Convert WOFF to OTF to make the font available in all applications including word processors and presentation software.
Preparing fonts for print production
Print workflows require desktop font formats. Convert WOFF to OTF to embed fonts in PDF files, prepare press-ready documents, or submit files to print vendors.
Inspecting font features in a font editor
Open the converted OTF in FontForge or Glyphs to inspect glyph outlines, kerning tables, OpenType feature code, and font metadata.

Frequently Asked Questions
Yes. All GSUB and GPOS features — ligatures, stylistic alternates, contextual forms, small caps, old-style figures — are part of the font data inside the WOFF wrapper and are preserved during extraction.
Yes. WOFF is a lossless container. The CFF cubic Bezier outlines are extracted exactly as they were before the font was wrapped in WOFF format.
Yes. The output is a standard OpenType font file. Install it through Font Book on macOS, the Fonts control panel on Windows, or your font manager on Linux.
WOFF can wrap either CFF or TrueType data. If the source contains TrueType outlines, the converter will still extract them. The output will be an OTF container with TrueType data.
No. The conversion is a technical format change. However, some font licenses restrict conversion or desktop use for web-only licenses. Check your font's EULA before converting.
No. The conversion runs entirely in your browser. Your font file never leaves your device, making it safe for licensed, proprietary, or unreleased fonts.
OTF with CFF outlines is preferred in professional typography, uses more efficient cubic curves, and is the standard output format for type design tools. Choose OTF for design workflows and TTF for maximum compatibility.
Yes, the OTF will be larger than the WOFF since WOFF applies zlib compression. Expect a 30-50% size increase when extracting to uncompressed OTF.
Yes. Both Figma and Sketch support OTF fonts. After converting from WOFF, install the OTF on your system and it will appear in these design tools.
The converter handles both automatically. If you need to check, open the converted file in a font editor — CFF fonts will show cubic curves and TrueType fonts will show quadratic curves.
