# Compress video to fit email or WhatsApp (under 25MB, no watermark)

Hit a specific file size target (25MB for email, 100MB for WhatsApp, or custom) without visible quality loss. Runs in your browser, your video never leaves your device.

1

Upload your video

Select any MP4, MOV, WebM, or MKV file to compress.

2

Set target size

Choose a size target (e.g., 25MB for email) or quality level.

3

Download compressed video

Get your smaller video file ready to share.

## Questions & answers

### My video is over the email size limit, will this actually get it under 25MB?

Yes. Set 25MB as your target and the encoder calculates the [bitrate](/learn/bitrate) needed to hit that size. If the source is extreme (e.g. 4K hour-long), you'll see how much quality drops before exporting.

### Will the compressed video look bad?

For most everyday compression (25-100MB targets from typical source files), quality loss isn't visible. Aggressive compression on detailed footage shows artifacts, so the preview lets you check before downloading.

### Does my video get uploaded anywhere?

No. Compression runs in your browser via WebAssembly, your video never leaves your device, and we keep nothing.

### What if I just need to change the format, not the size?

Use the [video converter](/tools/video-format-converter) for format-only changes (MP4 to WebM, etc.) without targeting a specific file size.
