Why 25 MB is the email number
25 MB is the size email settled on. Gmail won't send a message larger than 25 MB, and most other providers land on or just below the same figure — some Outlook plans stop at 20 MB. It's the one attachment limit almost everybody has run into, which is why it's the number people reach for the moment a video bounces back.
One detail catches people out: the cap applies to the whole encoded message, not to the file as it sits on your disk. Email encodes attachments in a way that inflates them by roughly a third, so a video measuring exactly 25 MB can still be refused. If it has to travel as an attachment, aim under the line rather than at it — or send a link instead, which is what most providers quietly do on your behalf above the limit anyway.
Beyond the inbox, 25 MB is simply the web's most common 'medium' limit. It was Discord's free ceiling for the stretch between the old 8 MB cap and today's ~10 MB, so plenty of guides still quote it, and it's the default for many forums, helpdesk tickets and CMS media libraries. As a video budget it's a comfortable one: 25 MB carries half a minute at full 1080p, a minute that still looks clean, and three minutes at a sensible 480p.
How much video fits in 25 MB?
These figures come from the same arithmetic the converter runs on your own file: the 25 MB budget, less a 128 kbps audio track, spread across the length of the clip. Megabytes are counted as 1,000,000 bytes and 2% is held back as a safety margin, so the result clears the limit whether the platform measures in MB or MiB. Length is the whole trade-off — the same budget over a longer clip means a lower bitrate. The resolutions below are a comfortable match for H.264 at 30fps; TinyVid does the real sum once it knows your video's exact duration.
| Clip length | Video bitrate | Comfortable resolution |
|---|---|---|
| 30 seconds | ≈6.4 Mbps | 1080p at full quality |
| 1 minute | ≈3.1 Mbps | 1080p — 720p if there's fast motion |
| 3 minutes | ≈960 kbps | 480p, or 720p for calm footage |
| 10 minutes | ≈200 kbps | 360p, and visibly soft |
Unlike the 8 MB target, nothing on this list fails outright — 25 MB has the budget to encode all four. Ten minutes is simply where the picture starts to hurt: if that's your clip and it's headed for a web page rather than an inbox, the 100 MB target gives it about six times the bitrate.
How to compress a video to 25 MB
- Drop your video onto the box above — the 25 MB target is already selected. Files up to 200 MB are free, with no account.
- If it's headed for email, aim a little under the line: encoding inflates attachments on the way out, so leave yourself some slack or plan to send a link.
- Optional: in Advanced settings, cap the resolution for a long clip, or mute a screen recording that doesn't need sound. The quality slider stays disabled while a target is set — the size is what decides the bitrate.
- Press Convert. TinyVid encodes in two passes: one to measure the video, one to spend the 25 MB budget where it counts.
- Download the MP4, attach it, and check your provider accepts it — or switch to a hosted link if the message still bounces.
