Compress a video to under 20 MB

Twenty megabytes is now the Discord limit for accounts without Nitro, and it is also where many Outlook setups stop.

  • Nothing is uploaded. Your browser does the compression, so the file stays on your device.
  • Lands under the real limit. We aim a little below it, so the upload goes through first time.
  • Fast. A 30 second 1080p clip fits into 10 MB in about two seconds on a desktop.
Where are you sending it?

Custom size 20.00 MB. We aim for 19.40 MB, a small safety margin so the file never lands just over.

Sent to our servers: 0 bytes. It all happens in this tab.

When you need 20.00 MB

Discord free accounts, Outlook email, and upload forms that allow a bit more than 10 MB.

What to expect

About a minute of 720p fits. Thirty seconds can stay at 1080p. Longer clips drop to 480p or 540p.

How much video fits in 20 MB

Worked out with the same maths the compressor uses, for a typical 1080p phone or screen clip with sound. Fast motion needs more room, still scenes and screen recordings need less.

How we hit the number

We work out how many bits each second of video can use: the target size, minus a safety margin, divided by the length, minus the audio. Then we pick the largest resolution that still looks clean at that rate and encode with your browser's built-in video encoder. If the result is still over, we automatically try once more at a lower rate.

The target we aim for is 19.40 MB, which is 600 KB under 20.00 MB, so the file is not turned away over a few bytes.

Questions people ask

Is this the Discord limit?

Yes. Discord raised the free limit from 10 MB to 20 MB in August 2026. We aim a little under it so the upload goes through.

Does it keep sound?

Yes, audio is kept at a sensible bitrate.

Limits change. We link the official page wherever there is one, and the safety margin means a small change is unlikely to matter. Last updated 2026-11-09.
