Compress a video to under 10 MB

Ten megabytes is the number people hit most: the free Discord limit, many company mail servers, and plenty of upload forms.

  • 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 10.00 MB. We aim for 9.70 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 10.00 MB

Discord free accounts, strict email systems, and many web forms. If you are sending by email, remember mail encoding adds about a third, so this size is a sensible choice there.

What to expect

About a minute of video fits at 480p to 540p. Thirty seconds can stay at 720p. Shorter clips keep full 1080p.

How much video fits in 10 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 9.70 MB, which is 300 KB under 10.00 MB, so the file is not turned away over a few bytes.

Questions people ask

How much video fits in 10 MB?

Roughly 20 seconds of 1080p, 40 seconds of 720p, or 90 seconds of 480p, depending on how much motion there is.

Is this the Discord size?

It matches Discord's old 10 MB limit. Free Discord accounts now get 20 MB, so use the Discord page for that.

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.
