Compress video
Same resolution, smaller file.
Drop the video to compress
MP4, MOV, WebM and MKV. Up to 10 minutes, 2 GB.
Phones record at very high bitrates now. A minute of 4K can easily be 400 MB - too much to share, email or upload. Compressing lowers the bitrate without touching the resolution: the picture stays the same size, the file gets smaller.
The quality slider sets the bitrate directly. Lower means a smaller file and more artefacts; higher means the opposite. Talking heads and locked-off shots compress very well; fast, detailed scenes are harder.
Your video is never uploaded. The work happens inside the browser, on your own device, and the page keeps working offline once it has loaded. So there is no upload to wait for, no queue, and no file sitting on somebody else’s server afterwards.
Compression is lossy and cannot be undone, and compressing the output again stacks the loss. Start from the best source you have and do it once.
Files up to 10 minutes and 2 GB. That is not a plan limit - it is what an ordinary laptop or phone handles comfortably. Trim a longer video first.
Common questions
- Does the resolution change?
- No. This only lowers the bitrate. To change resolution, use the resize tool.
- How much smaller will it get?
- It depends on the source and the quality you pick. Phone footage usually lands between a third and a fifth of its original size.
- Is the audio compressed too?
- Audio is re-encoded at 128 kbps AAC, which is plenty for speech and music.
- Why did some videos barely shrink?
- If the source was already encoded efficiently there is little left to take out. Busy scenes also need more bits.
