🛡️ Private Local Video Processing: Your videos never leave your device — all compression runs in your browser’s memory. No server uploads, no watermarks, no sign-up required.

Compress your video

Upload a video file and choose your quality level. Lower quality means a smaller file. The tool re-encodes your video at the selected settings entirely inside your browser.

How it works

Upload your video. MP4, WebM, MOV, AVI, or MKV.
Choose your quality and resolution. “Balanced” is a good default — it typically cuts file size by 40–70% with acceptable quality.
Download. The compressed file is generated on your device and never touches a server.

Common questions

How much smaller will my video get?

It depends on the source material, but typical reductions are 40–70% at the Balanced setting. Videos that were already heavily compressed (e.g. WhatsApp forwards) will see smaller gains.

Why is compression slow on my phone?

Mobile browsers use a single-threaded fallback for the video engine, which is safer but slower than the multi-threaded desktop path. Keep the tab open and your screen on — the tool will warn you if your browser tries to suspend it.

Is there a file size limit?

Desktop browsers handle files up to about 2 GB. Mobile browsers are capped at roughly 400 MB due to memory constraints. The tool checks your file size before starting and tells you if it’s too large.

Will this add a watermark?

No. There are no watermarks, ever. This tool is 100% free with no premium tier or upsell.
