Frequently Asked Questions

How do I compress a video for email attachment?expand_more

Upload your video and select "Small Size" or "Balanced" preset. Most email services limit attachments to 25MB. Our tool shows the output size in real-time so you can hit your target.

What formats does the compressor support?expand_more

All major formats: MP4, MOV, AVI, WebM, MKV, WMV, FLV, M4V. Output is always MP4 with H.264 encoding for universal compatibility across Slack, Discord, email, and web.

Is this tool safe for work videos?expand_more

Yes. All compression runs locally in your browser using WebAssembly. Videos never leave your device or touch external servers. No data is collected.

Can I compress videos for Slack or Microsoft Teams?expand_more

Absolutely. Slack allows up to 1GB with paid plans but compresses files aggressively. Pre-compressing to under 50MB with "Balanced" quality delivers better playback quality.

Why is my compressed video larger than the original?expand_more

Highly-compressed source videos (from phones or screen recorders) may not shrink further at "High Quality" settings. Try "Balanced" or "Small Size" for actual reduction.

How long does compression take?expand_more

Processing speed depends on your device. A 100MB video typically takes 30-60 seconds on modern laptops. Progress is shown in real-time.
