About this tool
Gmail, Outlook, and iCloud cap attachments at 25 MB, and many corporate mail servers stop at 10 or 20 MB. Instead of guessing at a compression level, pick the limit and the tool computes the bitrate that fits, encodes on your device, and re-encodes once more if the first pass overshoots.
Short clips keep near-original quality at these sizes; a long recording is reduced to 720p or 480p as needed. The output is a standard MP4 that opens on Windows, Mac, iPhone, and Android without extra software.
How to use it
- Drop your MP4, MOV, WebM or MKV file into the box above, or click to browse. Nothing is uploaded.
- Adjust the options if you want; the defaults suit most files.
- Click the button and wait a moment.
- Download the result.
Questions
Is a link better than an attachment?
For anything over 25 MB, yes: a shared drive link keeps the original quality. For a short clip, an attachment is simpler for the recipient, and this tool makes it fit.
How does it hit the size exactly?
It reads the video length, works out the bitrate that fits the budget with a small safety margin, encodes, and if the result still overshoots it lowers the bitrate and encodes again, up to three passes.
Will the quality be bad?
That depends on length: a 30 second clip at 10 MB looks fine at 720p, a 10 minute recording at 10 MB has to drop to 360p and will look soft. Trim the video first if you only need part of it.
Why is the output MP4?
MP4 with H.264 and AAC is what Discord, email clients, and phones play without fuss and what compresses most predictably.
