Compression
Up to 720p (HD). Usually 60–90% smaller and still looks great on phones.
The first time you use a video tool, your browser downloads the video engine (about 32 MB, once). Processing happens on your device, so long or 4K videos can take a few minutes — keep this tab open.
How to use the Compress Video tool

- 2
Choose a level (Recommended is 720p) or set a target size such as 25 MB.
- 3
Press Compress and download the smaller MP4.
Frequently asked questions
How do I compress a video to 25 MB?
Choose “Target size”, enter 25 MB and press Compress. The tool calculates the right bitrate from the video's length. Very long videos may need a bigger target to look good.
Is my video uploaded?
No. Compression happens in your browser, so your video never leaves your device.
Which level should I choose?
“Recommended” (up to 720p) gives big savings and still looks sharp on phones. “Strong” (480p) is best for messaging. “Light” keeps the original resolution.
What format is the result?
An MP4 file with H.264 video and AAC audio, which plays on iPhone, Android, Windows, Mac and all major websites.
Why does it take a while?
Video compression is heavy work and runs on your own device rather than a server. Keep the tab open; a few minutes per minute of HD video is normal.
