Decode WOFF2 locally with the bundled WebAssembly codec and wrap the SFNT tables as WOFF.
Processing uses bundled libraries in this browser. The download contains the generated file, rather than a link to a conversion service.
Start with the supported input, then check the generated result.
Choose Font file. The file stays in this browser; it is not saved by the page.
Read the supported input format and size limits before submitting.
Review a WOFF font decoded from WOFF2. Download the generated file and check it in the application where you plan to use it.
These workflows use the formats and behavior supported by this implementation.
Create WOFF when a target workflow accepts that container but does not handle the licensed source WOFF2.

The bundled codec decodes WOFF2 in the browser before the tables are wrapped as WOFF. No font is sent to a remote converter.

Check the output in its target application. Variable, CFF and color fonts are rejected rather than presented as supported conversions.

Keep the output format and conversion policy in view.
