mozjpeg-wasm

This library wraps mozjpeg-sys and exposes a few functions to perform decoding, encoding and simple transformation on JPEG images using mozjpeg.

Everything is compiled to WebAssembly and bundled in an NPM package which can be used directly in a browser.

Install

$ npm i @neslinesli93/mozjpeg-wasm

The library contains two files:

mozjpeg-wasm.wasm: it's the WebAssembly bundle that exposes all the functions to perform operations on JPEG images
mozjpeg-wasm.js: it exposes JS glue code that can be used to call the functions defined in the WebAssembly module

An example on the usage can be seen inside the JPEG.rocks repo

Prerequisites:

Then you can use the following script which builds the crate using wasm32-unknown-emscripten target and move the resulting js/wasm files to lib:

$ ./build.sh
