Where the 500 MB limit comes from
Canvas limits media uploads to 500 MB, X (Twitter) accepts up to 512 MB without Premium, and many video forms and portals stop at 500 MB. Phone 4K videos and camera footage pass that in minutes.
What fits into 500 MB
The compressor splits the size between picture and sound: about 96 kbit/s go to the sound, the rest to the picture. The longer the video, the fewer bits each second gets, so the resolution goes down to keep the picture clean rather than blocky:
| Length | Picture bitrate | Resolution |
|---|---|---|
| 10 minutes | 6.2 Mbit/s | 1080p |
| 20 minutes | 3.1 Mbit/s | 1080p |
| 30 minutes | 2.0 Mbit/s | 720p |
| 1 hour | 960 kbit/s | 480p |
| 2 hours | 432 kbit/s | 360p |
The target on this page is 490 MB — a little under 500 MB, because sites count megabytes differently and some add a few kilobytes on upload.
Tips
- 500 MB holds about 20 minutes of 1080p or 30 minutes of 720p — enough for most presentations and event clips.
- Longer? Use 720p, or split the video into 500 MB parts (Advanced settings → Trim, split & name).
How it works
- Add one or more videos — or a whole folder.
- The size is already set to 490 MB. Every video is compressed to fit it; short clips that already fit keep their quality.
- Press Compress. Everything happens in your browser: the video is never uploaded, so there is no file size limit and no queue.
Questions
How long can a 500 MB video be?
About 20 minutes at 1080p, 30 minutes at 720p or an hour at 480p with sound.
Will quality drop?
For most phone and camera videos the difference is not visible on a laptop or phone screen.
Is it really free?
Yes, free with no watermark and no account. The work is done by your device, so there is no server cost to charge for.
