How to email a video
- Leave “Email 25 MB” selected, or choose “Custom size” if your email provider has a lower limit.
- Drop the video in and check the expected size and quality.
- Compress, save, and attach the new file to your email.
Attachment limits
Gmail allows attachments up to 25 MB. Many other providers and company mail servers allow somewhere between 10 and 25 MB, so if you’re not sure, use the custom size and choose 10 MB to be safe.
Leave a little room for any other attachments: the limit usually counts the whole email, not each file.
Good for screen recordings
Screen recordings compress extremely well because most of the screen doesn’t change. A ten-minute walkthrough often fits in 25 MB at full sharpness.
Questions
Why not just use a cloud link?
A cloud link needs the recipient to open another service, and links can expire or need permission. An attachment just works.
What size should I pick for Outlook or a work account?
Limits vary by provider and company. If you don’t know yours, choose a custom size of 10 MB.
Is my video uploaded anywhere?
No. The tool runs inside your browser and uses your device’s own video encoder. Your file is read from your device, processed there and saved back. You can confirm this in your browser’s network panel: nothing is sent while a video is processed.
Which browsers does it work in?
It works best in Chrome and Edge on a computer. It needs a browser feature called WebCodecs. If your browser doesn’t have it, the page tells you before you start.
