Why Convert WOFF to OTF?

Converting WOFF to OTF is a common task whenever a file has to work somewhere that expects the other format. WOFF is the font format made for websites. OTF is the OpenType font format from Adobe and Microsoft. This converter makes the switch locally in your browser — nothing is uploaded.

Common use cases

  • You have a WOFF file and need it in OTF format.
  • The target software or platform requires OTF but your file is in WOFF.
  • Typical use of OTF: Preparing an OpenType font for the web as WOFF.
  • You want to reduce file size or improve compatibility without using desktop software.
Keep in mind: Converting a font does not change its licence, and OTF fonts with TrueType outlines cannot be turned into CFF here.
