Compress video
Make a video small enough to send: pick a resolution, or a target size such as 25 MB for email. Converted on your own device — nothing is uploaded.
MP4, MOV, WebM and most phone videos. Phones handle videos up to a few minutes best; use a computer for long or 4K videos.
Files stay in this browser tab. Close the page and they are gone.
How it works
- Add a video (MP4, MOV, WebM or a phone video).
- Choose a resolution, or a target file size.
- Press Compress and download the MP4.
Questions
How much smaller will my video get?
Phone videos usually shrink 70–90% at 720p with medium quality and still look good on a phone. Choose a file size if you need to fit a limit, such as 25 MB for Gmail attachments.
Why is it fast?
It uses the video encoder built into your phone or computer (WebCodecs), often hardware accelerated, instead of downloading a large converter. Long videos still take a while on older phones.
Which format do I get?
An MP4 with H.264 video and AAC audio — it plays on WhatsApp, iPhone, Android, Windows and Mac.
Are my files uploaded anywhere?
No. The tool runs entirely in your browser, so your files never leave your device and nothing is kept after you close the page. You can check it yourself: once the page has loaded, turn on airplane mode — the tool keeps working.
Is it free? Is there a file limit?
Yes, it is free, with no sign-up and no watermark. There is no upload limit because nothing is uploaded; very large files are limited only by your device’s memory.
