How to use this tool
- Add your files — drag them onto the page or choose them. They stay on your device.
- Pick a Compression level: Strong is selected to start, Recommended keeps more detail, and Extreme squeezes hardest for chat-app and email ceilings.
- Cap the Resolution or Frame rate under Options when the source is oversized for where it is going — capping usually saves more than the quality level does.
- Press “Compress videos” and download the results, individually or as one ZIP.
About this tool
Make videos small enough to email or upload, without wrecking them. Free and unlimited, and nothing is uploaded: it all runs in your own browser. Everything is analysed and produced on your own device — nothing is uploaded anywhere, and you can verify it: the tools keep working even offline.
Privacy & limitations
A file that is already tightly encoded may not get smaller. When re-encoding would make it bigger, you get your original back unchanged. Files over roughly 2 GB, or long 4K videos, can exhaust the browser's memory — everything runs on your machine, so your machine is the limit.

Frequently asked questions
How do I get a video under a specific size?
Lower the resolution first, then the quality. Halving the resolution cuts the data to roughly a quarter. There is also a tool that works backwards from a size limit and finds the best quality that fits under it.
What makes a video file large?
Bitrate, which is resolution and frame rate together, far more than length. A short 4K clip at 60 frames a second is bigger than a long 720p one.
Will compressing make it look bad?
Not at a sensible setting. The visible damage appears in fast motion and fine detail first, so a talking head survives compression far better than a landscape pan.
Is it better to trim or to compress?
Trimming, when there is anything to cut: removing thirty seconds you did not need costs nothing in quality at all, whereas compression always costs something.
