Who asks for 25 MB
- Gmail
- 25 MB: Personal Gmail accounts. Gmail takes the attachment out and puts a Google Drive link in the email instead.
- Outlook.com
- 25 MB: Outlook.com accounts. Outlook.com points you to sharing it from OneDrive, which takes files up to 2 GB.
What fits in 25 MB
| Picture | At full quality | Longest that fits |
|---|---|---|
| 1080p | 33 s | 1 min 13 s |
| 720p | 1 min 13 s | 2 min 35 s |
| 540p | 2 min 5 s | 4 min 15 s |
| 480p | 2 min 35 s | 5 min 26 s |
| 360p | 4 min 15 s | 8 min 35 s |
Shycut’s own sums for a 16:9 video at 30 frames a second with sound, at Balanced quality. “Full quality” keeps the bitrate Balanced would use anyway; past “longest that fits”, Shycut makes the picture smaller instead of letting it break up. An upright video fits the same.
Your video, by length
| Length | Comes out as |
|---|---|
| 30 s | 1080p, full quality |
| 1 min | 1080p, 3,072 kbps for the picture |
| 3 min | 540p, 939 kbps for the picture |
| 10 min | Too long: up to 8 min 35 s fits |
For a 1080p video at 30 frames a second with sound. The save window does the same sum for your own video before anything is made.
Why 25 MB is the email number
Both big mail services list 25 MB as their attachment limit, as their help pages above say. Over it, Gmail turns the file into a Drive link and Outlook.com points you to OneDrive: the person you write to gets a link to open instead of a video.
An attachment arrives in the email itself and stays there. For a short clip, compressing it to fit is often the friendlier way to send it.
How it works
Open your video
Press the button and drop the file, or pick it from your files. It opens in this browser tab; nothing is uploaded, so the original can be as large as you like.
25 MB is already set
The save window opens set to an MP4 under that size. Shycut works out the bitrate from your video’s length and shows what it will do before you save.
Save
If the video can’t fit at its own size, the picture steps down (1080p, 720p…) and the window says so. If nothing fits, it tells you how long a clip does, so you can trim first.
Where these facts come from
Questions
Does 25 MB count the whole email?
Gmail speaks of the total attachment size, so keep other attachments in mind; the email page here aims a little lower to leave room.
What if my video needs more than 25 MB?
Then it can’t go as an attachment without losing size; trim it, or send a link from your own cloud storage instead.
Can I attach the result from my phone?
Yes. Shycut runs in the phone’s browser too, and the compressed file is saved where downloads go.
Your video stays with you.
Open Shycut, drop the video in and export. Free, with no account, and your video never leaves your device.
