Compress a video to send by email.
Gmail caps attachments at 25 MB and Outlook at 20 to 25 MB, and emailing adds about a third to a file's size on the way. This makes your video 18 MB, so it attaches and arrives.
- 100% free
- No watermark

How it works
How to compress a video, free, in three steps.
1
Drop in your video
MP4, MOV or WebM, of any size: a phone video, a screen recording, a 4K camera file. It opens in your browser; nothing is uploaded.
2
Choose a size or a quality
Type the size it has to fit under, like 20 MB for Discord, or choose Small, Balanced or High quality. You see the resolution and the expected size before you start.
3
Download the smaller MP4
An H.264 MP4 that plays everywhere. If it comes out over your size, it's made again smaller, automatically, until it fits.
Why this one
Free, with nothing held back, and nothing uploaded.
Hits the size you need
Ask for under 20 MB and you get under 20 MB: the bitrate is worked out from the length, and the file is checked and redone if the encoder overshoots.
Looks as good as it can
Rather than starving a 4K picture of bits, the resolution steps down to what the size can carry cleanly, and 60 fps drops to 30 when bits are short.
No upload, no waiting
Compressing on your own device skips the slowest part of every online compressor: uploading a big file and downloading it again. The browser's hardware encoder does the work.
Free, with no limits
No watermark, no sign-up, no file size cap of ours and no daily limit. Compress as many videos as you like.
Your file is opened and processed by your own browser. It is never sent to a server, so it stays private, and there’s no upload to wait for.
Why video attachments bounce
Gmail allows 25 MB of attachments per email, and Outlook 20 to 25 MB depending on the account. Those limits apply to the message as it's sent, and attachments are encoded on the way, which makes them about a third bigger. A 22 MB video can be refused even though it looks under the limit.
This page makes the video 18 MB, which fits after encoding with room to spare. It comes back as an H.264 MP4, which plays on any phone or computer without the recipient installing anything. For anything long, a shared link is still the better route.
