This is a browser extension that brings JPEG XL support for browsers.
It uses a WebAssembly implementation of libjxl.
git clone https://github.com/zamfofex/jxl-crx
cd jxl-crx
scripts/build.sh
This will download and build dependencies and create jxl-mv2.zip and jxl-mv3.zip output files in this repository’s directory.
Note for Guix users: You may prefer to use scripts/guix-build.sh instead, which will set up a FHS container with the necessary package dependencies for you. However, note that binaries will still be downloaded, so the container has network access.
