Compress Video for WhatsApp
WhatsApp has long limited videos sent as media to around 16 MB and re-compresses them heavily. Compressing to 16 MB yourself gives you control over quality. If your app allows more, raise the target.
How it works
- 1
Select your video
Drop in an MP4, MOV, WebM, or MKV file. It opens directly in your browser.
- 2
Check the target size
The target is preset for this page. Change it if you need a different size, and lower the resolution for long videos.

Compress and download
The video is re-encoded on your device. Compare the before and after size, then download the MP4.
Frequently Asked Questions
Why compress before sending instead of letting WhatsApp do it?
WhatsApp applies strong compression automatically. Compressing to the limit yourself, at a resolution you choose, usually keeps the video sharper.
How accurate is the target file size?
The tool calculates the bitrate needed to hit your target from the video length. The result is usually close to the target but can differ slightly, because encoders adjust the bitrate to the content.
Is my video uploaded to a server?
No. Your file never leaves your device — compression runs locally in the browser using WebCodecs, so it also works for private videos.
Is this video compressor free?
Yes. It is free with no account, no watermark, and no limit on how many videos you compress.
