Frequently Asked Questions
How much can I compress a video?+
Typically 50-90% reduction depending on the original quality and your compression settings. A 100 MB video can often be reduced to 10-30 MB at medium quality with little visible difference.
Does compressing a video reduce quality?+
Some quality loss is inherent in compression, but at medium-high settings the difference is barely noticeable. The tool lets you preview the result before downloading so you can find the right balance.
What video formats are supported?+
Upload MP4, WebM, or MOV files. The compressed output is always MP4 (H.264) which is universally compatible with all devices and platforms.
Is my video uploaded to a server?+
No. All compression happens locally in your browser using FFmpeg WebAssembly. Your video never leaves your device. Nothing is stored anywhere.
Why is compression slow?+
Video encoding is CPU-intensive work. Processing happens in your browser via WebAssembly, which is slower than native software. Shorter videos and lower resolutions process faster.
Can I compress videos for email or Discord?+
Yes. Email typically limits attachments to 25 MB, Discord free tier to 25 MB. Use medium or high compression to get your video under these limits.
