Bundle a pile of files into a single ZIP or squeeze down bloated images without sending anything to a server. Everything runs in your browser tab using WebAssembly, so a 200MB folder of photos never leaves your laptop. Drop in files, pick your compression level, and download the result — no account, no queue, no upload progress bar to babysit. It keeps working even with your Wi-Fi off.
No. All compression happens inside your browser tab with WebAssembly. Your files stay on your device and are never sent to us or any server.
You can ZIP any file type — documents, PDFs, code, video, whatever. For image optimization, JPEG, PNG, and WebP are supported with adjustable quality settings.
There's no server limit since nothing is uploaded. The practical ceiling is your device's available memory, so very large batches depend on your computer's RAM.
Every tool runs entirely in your browser. Files are never uploaded — 100% private and free.
