The video compressor & converter that never sees your video
Milzune is a free video converter and compressor that runs 100% in your browser. Your file is processed on your own device — it never leaves it. No uploads, no account, and nothing to install.
Everything you need, nothing you have to install
Convert video without installing software, shrink files for email, and keep every frame private — all from one elegant, browser-based toolkit.
Convert
Switch between MP4, MOV, AVI, WebM, and GIF in a couple of clicks. Auto-detects your input format so you only choose the output.
Batch Pro
Queue multiple videos and let Milzune work through them one after another — ideal for content creators and busy inboxes.
Privacy by design
A truly private video converter — no upload, no cloud queue, no copies of your footage on someone else's server. It can't leak what we never receive.
Free to start. Pro costs one payment, once.
No subscription, no renewal, nothing to cancel — because nothing recurs.
How it works
Three steps, and your video never leaves your device.
Pick your video
Drag and drop a file, or browse for it. Nothing is transmitted anywhere — the file is simply opened by your browser.
Process locally
Your device does the work using in-browser video processing. Watch the progress bar — no queue, no waiting on a server.
Download
Save the finished file straight from your browser. Close the tab and every trace of the video is gone.

“Our legal team wouldn't approve cloud converters. Milzune processes everything locally, so it passed review in a day.”
“WebM to MP4 in the browser, no watermark, no signup. I paid for Pro just to support it.”
