Quick answer: To compress a video to 25 MB, open it here, keep the 25 MB target and download the MP4. The tool works out the bitrate from the length of the video, lowers the resolution when it has to and encodes again if the first try overshoots; about a minute of video fits at 720p. Nothing is uploaded.
An upload form, a support ticket or an app says "max 25 MB" and your video is ten times that. Keep the 25 MB target, check the estimate, and get an MP4 that lands just under it.

- Check the result on the page, then download the MP4.
How long a video fits in 25 MB
25 MB is about 200 megabits. The longer the video, the fewer bits each second gets, so the tool lowers the resolution to keep the picture clean rather than blocky. For a typical 30 fps video with sound:
| Length | Resolution the tool picks | How it looks |
|---|---|---|
| 1 minute | 720p | Sharp on a phone and fine on a laptop |
| 2 to 3 minutes | 540p | Good on a phone, a little soft full screen |
| 5 minutes | 360p | Watchable, details are soft |
| 10 minutes or more | 240p | Only for talking heads or slides |
These are estimates; busy scenes such as sport or gameplay need more data than a person talking. The page shows the estimate for your own file before you start, and warns you if the video is too long to fit at a watchable quality.
Where a 25 MB limit comes up
- Email: Gmail, Yahoo Mail and Proton Mail allow 25 MB per email. That limit counts the whole encoded message, and encoding makes an attachment about a third bigger, so a video of exactly 25 MB will not attach. Use compress video for email, which aims lower for you.
- Upload forms and help desks: many contact forms, support tickets and job portals cap each file at 25 MB or thereabouts. The page itself states the real number.
- Chat apps: Discord's free limit is 20 MB, not 25; compress video for Discord has the right targets.
More limits are in our list of file size limits of popular apps.
Getting more quality out of 25 MB
- Cut it shorter: half the length means twice the bitrate. Trim the video to the part that matters first.
- Drop the sound if nobody needs it: tick Remove the sound and the audio's share goes to the picture.
- 60 fps footage is halved to 30 fps automatically when the budget is tight, which looks better than a blurry 60 fps.
Your video is compressed by your own browser and never uploaded. If 25 MB is simply too small for it, send the original with a link instead, free up to 20 GB.

Frequently asked questions
How do I compress a video to 25 MB?
Open it here, keep the 25 MB target and press Compress to 25 MB. The tool picks the bitrate and resolution that fit and checks the result, encoding again a little smaller if it overshoots.
Can I email a 25 MB video with Gmail?
Usually not: Gmail's 25 MB limit counts the encoded email, which is about a third bigger than the file. Aim for about 18 MB, or use the compress video for email page, which does that for you.
How long a video can fit in 25 MB?
About a minute at 720p or two to three minutes at 540p for a typical phone video. Longer videos get a lower resolution, and very long ones are flagged before you start.
Is my video uploaded?
No. It is compressed in your browser on your device, with no watermark.
