Compress a video for email
Gmail takes attachments up to 25 MB per message. This aims under 18 MB, which leaves room for how email encodes files.
Your file never leaves this device. Everything runs in your browser.
How it works
- Pick where it's going: Discord, email, Outlook, WhatsApp, a size of your own, or a quality level.
- Drop your video. The tool works out the resolution and bitrate that fit.
- Download the smaller MP4.
Questions
Why 18 MB and not 25?
Email sends attachments encoded as text, which makes them about a third bigger on the way. 18 MB of video travels as about 24 MB, under Gmail's 25 MB. Sending from Outlook? Its limit is lower: use the Outlook target.
What if it still won't fit?
Trim the video to the part that matters, or send a link instead. Gmail turns bigger files into a Google Drive link.
Does my video get uploaded?
No. The video is read and re-encoded by your browser, on your device. This page can't send the file anywhere: its security policy only allows it to talk to its own site and to the page-view counter.
Why is the file still bigger than I hoped?
A size target is spread over every second of the video. A long video in a small target would need a bitrate so low the picture falls apart, so the tool lowers the resolution first and tells you when even that isn't enough. Trimming the video is the other way down.
What format do I get?
An MP4 with H.264 video and AAC sound, which every platform and phone plays.
Is there a size limit?
Files up to 2 GB and videos up to 15 minutes. Longer videos are better trimmed first.
