How to compress a video
- Pick a resolution and quality (720p, medium suits most uses).
- Choose your video and wait while it's compressed on your device.
- Check the result and the new size, then download it.
Typical size limits
- Email: 20–25 MB per message in Gmail and Outlook.
- WhatsApp: videos are compressed automatically; sending a smaller file first keeps more control over quality.
- Discord: 10 MB for free accounts.
Only need part of the video? Trim it first, which also makes it smaller.
Frequently asked questions
How much smaller will my video get?
Phone videos often shrink by 50–90%. Lowering the resolution (for example from 4K or 1080p to 720p) saves the most; the quality setting fine-tunes it. You'll see the new size before downloading.
What settings should I use for WhatsApp or email?
720p at medium quality keeps videos sharp on phones and is usually small enough for WhatsApp. For email, which often limits attachments to 20–25 MB, try 480p or low quality for longer videos.
How long does it take?
The video is re-encoded on your device using its built-in video encoder. On a modern computer, a one-minute 1080p video takes a few seconds to a minute; phones are slower.
Is my video uploaded?
No. Compression happens in your browser, so private videos stay on your device.
