How to compress a video for Discord, WhatsApp or e-mail

Chat apps and e-mail limit how big a video can be. Discord’s free upload limit is 10 MB, Gmail attachments stop at 25 MB, and WhatsApp re-compresses the videos you send, often making them blurry. Compressing the video yourself first puts you in control of the quality.

Step by step

1. Open the video compressor.
2. Drop your video in the box, or click to choose it.
3. Pick a target size: 10 MB for Discord, 25 MB for e-mail, or type your own.
4. Click Compress and wait. Your browser does the work, so the video is never uploaded.
5. Download the new MP4 and send it.

How sharp will it look?

The size budget is spread over the whole video, so shorter videos look much sharper. For a 10 MB target, Octooly picks roughly:

If you only need part of the video, use Trim to keep just that part. It makes a bigger difference than any setting.

Tips for WhatsApp

• WhatsApp re-compresses videos sent the normal way. If you want the receiver to get your file exactly as it is, send it as a document instead.
• Start with a target of about 15 MB. If WhatsApp still complains, try a smaller size.

Is it safe?

Yes. The compression runs inside your browser, on your own computer. Your video is never uploaded to Octooly or anyone else.
