Compress video on your Mac
Smaller files, same quality. Offline and unlimited.
Shrink large MP4, MOV and MKV videos so they fit email limits, upload faster or save disk space — without the quality falling apart. Everything is processed locally on your Mac, so there is no upload wait, no size cap and no watermark on the result.

The smaller video is rendered on your Mac and saved instantly.
Why do it on your Mac

Compress huge 4K files that online tools reject.
No watermark
The output is clean — no stamp, no quality throttling.
Private & fast
Nothing is uploaded, so it is faster and your footage stays yours.
Frequently asked questions
Will compression ruin the quality?
No — you choose the balance. Modern encoding keeps videos looking great at much smaller sizes.
Is there a file-size limit?
No. Because it runs on your Mac, you can compress files of any size.
Does it add a watermark?
Never. The compressed video has no watermark.
