Compress video online, privately

Reduce video file size without losing what matters

Modern phones and screen recorders produce beautiful footage — and enormous files. A one-minute 4K clip can easily weigh several hundred megabytes, far beyond what email providers, messaging apps, or course platforms will accept. A good video compressor re-encodes that footage more efficiently, so you keep the resolution and smoothness while the file shrinks dramatically.

Milzune gives you two ways to shrink video size. Quality presets are the fast path: pick High Quality for archiving, Balanced for everyday sharing, or Max Savings when the smallest possible file matters more than pixel-perfect detail. Target file size is for hard limits — tell Milzune the file must come in under 25 MB for an email attachment, and it calculates the bitrate needed to hit that number.

Why compress in the browser?

Most online video file size reducers work by uploading your footage to their servers, compressing it there, and letting you download the result. That means your video — your face, your screen, your client's product demo — sits on infrastructure you don't control. Milzune takes the opposite approach: the compression engine runs inside your browser tab, so the file never leaves your device. You can read exactly how on our How It Works page.

The free tier handles files up to 100 MB, three times a day, with no watermark. If you regularly shrink bigger footage, Milzune Pro removes the caps with a one-time payment — not a subscription.
