Where the 50 MB limit comes from
Zendesk, many support portals, intranets and learning systems cap each file at 50 MB. It is enough for several minutes of good-quality video — if the bits are spent well.
What fits into 50 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 |
|---|---|---|
| 30 seconds | 12.6 Mbit/s | 1080p |
| 1 minute | 6.2 Mbit/s | 1080p |
| 3 minutes | 2.0 Mbit/s | 720p |
| 10 minutes | 538 kbit/s | 480p |
| 20 minutes | 221 kbit/s | 240p |
| 30 minutes | — | too low: trim it |
The target on this page is 49 MB — a little under 50 MB, because sites count megabytes differently and some add a few kilobytes on upload.
Tips
- Screen recordings: keep the original resolution — 50 MB holds 10+ minutes of a UI demo.
- Phone video: 1080p at 30 fps is plenty; 4K just eats the budget.
How it works
- Add one or more videos — or a whole folder.
- The size is already set to 49 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 50 MB video be?
About a minute at 1080p, 3 minutes at 720p or 10 minutes at 480p with sound.
Can I compress a 2 GB file to 50 MB?
Yes — there is no input size limit, because the file is never uploaded. Long videos just come out at a lower resolution.
Does it keep the original?
Yes. The compressed copy is saved next to it or into a folder you choose.
