ImZip is an online image compression utility capable of:

  1. Batch image compression;
  2. Fully local - your files aren't sent to ANY server.
  3. Free & Open source!

Please wait for a bit before the WebAssembly loads. If nothing comes out after a good while, it's very possible that your browser is too old to support WASM (or you have it disabled, you privacy nerd.) In both cases, sorry! ImZip won't be able to run.
