Ready.
Sendable video, with realistic limits
Email limits vary by provider, and attachments can be encoded by mail clients after upload. This tool focuses on creating a smaller MP4 before you attach it.
If your source video is long, a link may be better than an attachment. Local compression cannot make every long video readable under 25MB.

Frequently asked questions
Is 25MB universal?
No. It is a common attachment target, but providers and recipients can have different limits.
Will it reduce resolution?
Yes, when needed. Lower resolution is one of the most reliable ways to reduce file size.
Can I use this for private work videos?
The file stays in the browser tab, which avoids uploading the source to a third-party converter.
