Compress Video to 25MB
25 MB is the number most services print on the page — mail providers, helpdesks, upload forms — and it is roomy enough that an ordinary clip keeps its full resolution. It is pre-filled here, and the finished file is measured against it before you download anything.
What to know about 25 MB
The most widely advertised limit there is
Mail providers quote it, ticket systems quote it, and a great many upload forms inherited it from whichever mail server they were written next to. It is the first number worth trying when a service refuses a file and does not say why.
This is where 1080p starts to survive
25 MB is two and a half times the Discord budget, and that is usually the difference between a downscale and none at all for a clip of a minute or two. The table below shows where the ladder still steps in, because duration decides that rather than the target alone.
The one place 25 MB fails is email
Attachments are base64-encoded before they are sent, which makes them about a third larger in transit, so a file that is exactly 25 MB meets a 25 MB limit as roughly 33 MB and bounces. Aim at 16 MB for anything that has to travel as an attachment.
What fits in 25 MB
| Clip length | Video bitrate | Resolution it picks |
|---|---|---|
| 15 seconds | 12756 kbps | 1920×1080 |
| 30 seconds | 6314 kbps | 1920×1080 |
| 1 minute | 3093 kbps | 1440×810 |
| 3 minutes | 946 kbps | 720×406 |
| 5 minutes | 516 kbps | 480×270 |
These rows come from the same planner the tool runs, so they are what it would actually choose — not a rule of thumb. Your own clip has its own length, resolution and audio track, and the plan is recomputed against those before anything is encoded. Where a row says the target is out of reach, dropping the audio or trimming the clip changes the arithmetic in your favour; the bitrate calculator does the same sum for a target you type yourself.
Frequently asked questions
Is 25 MB enough to keep my video at 1080p?
For a short clip, usually yes — that is the practical difference between this target and the 10 MB one. Length is what decides it: the planner keeps the source resolution while the bitrate can carry it and steps down when it cannot, and it shows you which of those it chose before the encode starts.
My 25 MB file was rejected by a 25 MB email limit. Why?
Because mail limits apply to the encoded message, not to your file. Email is a text protocol, so an attachment is base64-encoded on the way out and grows by about a third — 25 MB of video becomes roughly 33 MB of message. The fix is to aim under the advertised number; 16 MB reliably fits a 25 MB provider.
Is 25 MB here the same 25 MB the service means?
It is 25 × 1024 × 1024 bytes, which is how the platforms that publish these limits measure them and how your operating system reports file sizes. The decimal reading of the same number is about 5% smaller, and the safety margin the planner takes is wider than that gap, so a file that lands here lands either way.
Can I aim at a number that is not on the list?
Yes — choose Custom and type it. Anything from 1 MB up to 2000 MB is accepted, and the plan updates as you type, so you can see what a given target does to the resolution before committing to an encode.
