Compress a video
Make a video small enough to email or message — with a real H.264 encoder running in your browser. No upload (that's the slow part of every other site), no watermark, no arbitrary length caps.
How it works
- Drop your video and pick a quality: Smallest, Balanced or Higher quality. Optionally cap the resolution — 1280 px is plenty for messaging.
- Compress. Fair warning: encoding runs on your CPU (that's the privacy trade), so expect roughly the video's own duration, sometimes more. The progress bar is real, not decorative.
- Download the MP4 — H.264 + AAC, plays everywhere, web-optimized (faststart).
Frequently asked questions
Why is it slower than [big site]?
Because the work happens on your device instead of a server farm — which is also why your video never leaves your hands and there's no upload wait, no queue, no size cap and no watermark. For short-to-medium clips the total time is often comparable once you count the upload.
How much smaller will my video get?
Phone recordings typically shrink 50–80% at Balanced with no visible loss — they're encoded generously at the source. Screen recordings shrink even more. Already-compressed downloads may not shrink much; the result screen shows honest before/after numbers.
Does it work for long videos?
Yes, within your device's memory (roughly 1.5 GB input). An hour-long lecture works, but expect a long encode — a laptop plugged in and left alone does it fine.
Is there a watermark or sign-up?
No and no. Every tool on this site is fully free.
