How to compress video
- Add your file. Drop a video or image onto the tool or browse for it.
- Choose a target. Set a quality level or target size to balance smaller output against fidelity.
- Compress. Re-encode the file locally and compare the before and after sizes.
- Download. Save the smaller file to your device.
Upload caps are everywhere — email attachments, form fields, chat apps — and a single high-bitrate clip or a burst of camera photos blows past them fast. Compressing locally solves that without handing your media to a third-party server.
The biggest savings come from lowering bitrate and, where acceptable, resolution; a moderate setting typically keeps footage and photos looking clean. You see the resulting size immediately, so you can trade quality against size deliberately rather than guessing.
If you only need a different container, use the Video converter instead. To change an image's dimensions specifically, use Resize & convert, and to cut a video to just the part you need before compressing, use Trim video.
Frequently asked questions
How much smaller will my file get?
It depends on the source. Long or high-bitrate videos and high-resolution photos have the most to trim; already-optimized files change little.
Does compressing hurt quality?
Some loss is unavoidable when re-encoding, but a moderate level is usually visually indistinguishable while cutting size substantially.
Can I compress to a specific size?
You can aim for a target by lowering resolution or bitrate; the tool shows the resulting size so you can dial it in.
Is anything uploaded?
No. Both video (FFmpeg) and image compression run in your browser tab; the file's bytes stay on your device.
