01Why 25 MB

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.

02What fits

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 lengthVideo bitrateComfortable resolution
30 seconds≈6.4 Mbps1080p at full quality
1 minute≈3.1 Mbps1080p — 720p if there's fast motion
3 minutes≈960 kbps480p, or 720p for calm footage
10 minutes≈200 kbps360p, 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.

03Step by step

How to compress a video to 25 MB

  1. Drop your video onto the box above — the 25 MB target is already selected. Files up to 200 MB are free, with no account.
  2. 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.
  3. 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.
  4. Press Convert. TinyVid encodes in two passes: one to measure the video, one to spend the 25 MB budget where it counts.
  5. Download the MP4, attach it, and check your provider accepts it — or switch to a hosted link if the message still bounces.
04FAQ
01How do I compress a video to 25 MB for email?
Drop the file above and press Convert — the 25 MB target is already selected, so TinyVid works out the bitrate that fits your clip's exact length and encodes an H.264 MP4 in two passes. It's free up to 200 MB with no sign-up, and the result lands at or just under 25 MB.
02Will a 25 MB video actually send through Gmail?
Usually, but it's tighter than it looks. Gmail's 25 MB cap applies to the encoded message rather than the file on disk, and encoding adds roughly a third — so a file sitting exactly on the limit can still be refused. Leave some headroom, or let Gmail put it on Drive and send a link instead. If it must be an attachment, the 8 MB target is the size nothing argues with.
03What quality can I expect from a 25 MB video?
Better than most people assume. Half a minute fits at a full 1080p bitrate, and a minute still looks clean at 1080p. Three minutes drops into 480p territory and ten minutes to 360p — the budget is fixed, so quality is really a question of length. The table above has the numbers.
04Was 25 MB ever Discord's upload limit?
Yes — it was the free limit for a period between the long-standing 8 MB cap and the roughly 10 MB free ceiling in place today, which is why plenty of older guides still quote it. For Discord specifically, check the current limit before you rely on 25 MB; for email and most forums, it's still the right number to aim at.
05Can I send a link instead of an attachment?
For video that's often the better answer. TinyVid's hosted plan stores the converted file on a CDN and gives you a URL and an embed snippet for a flat monthly price, so the message stays small and the video streams instead of downloading. For a one-off, converting to 25 MB and attaching it is still the quickest route.
06Does the video keep its audio at 25 MB?
Yes. TinyVid reserves a 128 kbps audio track inside the budget and gives the rest to the picture, so a 25 MB clip keeps normal sound at every length in the table above. If the audio doesn't matter — a screen recording, a silent demo — muting it in Advanced settings hands those bits back to the video.
