About

A 25 MB limit comes up in email, in upload forms, in course and student portals and in support ticket systems. Each service sets its own cap, and caps change, so check the form or mail service you are using before you start. This page opens the Video Compressor with the 25 MB target already selected, so you can drop in a file and get a smaller copy in a few steps.

At 25 MB, the length of the video decides how much detail survives. A short clip keeps its picture sharp. A long lecture or meeting recording has to share the same space across many more seconds, so the picture softens, most of all when things move quickly. If the video is longer than the size allows, shorten it first, or lower the Resolution to 720p or 480p so the frames need less data.

Sound is kept by default. Turn Keep sound off when the picture is what matters, such as a silent demo or a screen recording with no narration, and the whole budget goes to the picture. If the target cannot be reached at that length, the page says so. Then you can turn sound off, pick a larger size, or shorten the video before you compress it again.

Reduce a large recording before you move it into a shared folder or keep it for later.

Questions

How long a video fits in 25 MB?

It depends on the content and the settings you choose. The tool sets the picture quality from the length and the size you pick, so a shorter video keeps more detail. If 25 MB is very small for the length you loaded, the page warns you before you start.

Will the quality look worse at 25 MB?

It depends on how long the video is. The same 25 MB gives a short clip much more detail than a long one. Fast movement and fine text soften first, so check the result before you send it.

Should I turn off sound to get under 25 MB?

It can help on a long video. Turning off Keep sound gives the picture the whole budget. For a silent demo that is the best choice. If the file is still over the target, shorten the video or lower the Resolution.

What if the video will not get under 25 MB?

The tool checks the result against your target and tries again with a lower setting, up to three times. If it is still over, the page says the target cannot be reached at that length. Turn sound off, shorten the video, or pick a larger size if your destination allows it.
