Make a video file smaller without uploading it anywhere. Your browser re-encodes the clip to a leaner MP4 using your device’s own hardware, so even large private videos stay on your machine.

Handy for email limits, slow uploads, messaging apps and saving storage. Pick how hard to squeeze, optionally drop the resolution to 720p or 480p, and download.

How to compress a video

  1. Drop an MP4, WebM or MOV video.
  2. Choose a compression level (and optionally resize to 720p/480p).
  3. Compress, then download the smaller file.

Frequently asked questions

Is my video uploaded to a server?

No. The video is decoded and re-encoded entirely in your browser — nothing leaves your device.

How small will it get?

It depends on the clip. Choose “Small file” and/or resize to 720p/480p for the biggest savings; the tool shows the before/after size.

Will quality drop?

Compression always trades some quality for size. “High quality” keeps it close to the original; “Small file” squeezes hardest.

Is there a size limit?

No file-size limit — it runs on your device. The free version covers shorter clips; a one-time unlock removes the length limit.
