Transfigure — Free Private File Converter
Transfigure converts images, documents, spreadsheets, audio and config
files entirely inside your browser using Rust compiled to WebAssembly.
Files never leave your device — there is no upload, no account, and no
tracking.

Batch conversion is supported, with results downloadable individually
or bundled as ZIP, TAR.GZ, TAR.XZ or 7Z. This page requires JavaScript
and WebAssembly to run the converter — enable JavaScript to use the
app interactively.
