How long a video fits in 5 MB
These are the picture sizes the tool picks for a 1080p phone video, with and without its sound (≈ means about; soft means visibly blurry):
| Length | With sound | No sound |
|---|---|---|
| 15 sec | ≈750p | ≈770p |
| 30 sec | ≈510p | ≈540p |
| 1 min | ≈360p | ≈380p |
| 2 min | ≈240p, soft | ≈270p, soft |
| 5 min | ≈120p, soft | ≈170p, soft |
| 10 min | too long, needs 10 MB | ≈120p, soft |
About a minute is the practical limit. Longer videos still fit for a while, but they come out too soft to watch comfortably.
Getting the most out of 5 MB
Trim first. Cut the video to the part that matters with the video trimmer, then compress the clip. Half the length gives each second twice the room.
Drop the sound if nobody needs it. Untick "Keep the sound" and the picture gets the whole 5 MB, as the table shows.
Check the form's real limit. If it says 5 MB, the tool's default already leaves a small margin, so the file is accepted however the form counts megabytes.

Why your video never leaves your computer
Online video tools upload your file to their servers, process it there, and send it back. That is slow for big videos and costs them money for every minute, so free plans cap your file size or add watermarks, and your video sits on someone else's computer.
Here your own computer does the work, inside this tab. Nothing is uploaded, so there is nothing to cap: no file size limit, no daily limit and no watermark.
Questions
Can a 5-minute video fit in 5 MB?
Technically yes, but at about 120p it is too blurry to be useful. Trim it to a minute or less for a picture people can watch.
The tool says my video is too long. What now?
It shows the smallest size that still gives a watchable picture. Trim the video to a shorter clip, or pick a bigger size if your limit allows it.
Why does Windows show my file as 4.7 MB?
Windows counts sizes in steps of 1,024, so a file of 5,000,000 bytes shows as about 4.7 MB there and 5 MB on a Mac. It is the same file.
Is it really free?
Yes. Your computer does the work, so a video costs us nothing to process. No account, no watermark, no limits.
Is my video uploaded?
No. It is processed inside this browser tab and saved straight back to your computer.
Which browsers work?
Recent Chrome, Edge and Safari on a computer. Chrome and Edge are fastest on most machines. Phones work for short videos.
How long does it take?
In Chrome, a one-minute 1080p video took 13–19 seconds on the laptops we tested and about 40 seconds on a computer without a graphics chip. Safari can be slower.
Can I close the tab while it works?
Keep the tab open and in front until it finishes. Browsers slow down background tabs.
