Compress Video Online Free — Shrink Video Size
Runs 100% in your browser — your files never leave your device.
Videos are too big for email, chat apps, and storage plans until you compress them. Pick a balance between size and quality and let the encoder do the rest — typical files compress locally, oversized ones on our servers where they live at most an hour. Watermark-free always.
How it works
- 1
Add your video
Typical sizes compress right inside your browser.
- 2
Choose your balance
Prefer better quality or smaller file — the encoder adapts.
- 3
Download the smaller video
Server-processed files: delete them right after processing, or let them auto-delete within an hour.
About this tool
How video compression works
Compression re-encodes the video at a lower bitrate and resolution — the encoder discards detail the eye contributes least, trading size for fidelity at a ratio you control. Upload limits and slow connections are the usual reasons.
Choosing the compression level
Strong compression suits messaging apps and quick shares; lighter compression preserves quality for platforms that re-encode anyway. Watch a scene with fast motion after compressing — motion is where heavy compression shows first.
Compress after trimming
Remove the dead footage first with the trim tool, then compress — compressing frames nobody will watch wastes size on nothing.
Frequently asked questions
How much smaller will my video get?
Depends on the source: uncompressed or lightly compressed footage shrinks dramatically; already-compressed videos shrink less. The tool shows the result size before you commit to it.
Is my video uploaded anywhere?
Small videos compress entirely in your browser. Larger ones process on our servers and auto-delete within one hour — nothing is kept.
Why does fast motion look worse after compression?
Compression saves space by reusing information between frames, and rapid movement defeats that reuse. Lower compression levels keep motion smooth at larger sizes.
