Frequently Asked Questions
How does video compression work?▼
Video compression re-encodes the video at a lower bitrate, reducing file size. The quality slider controls the trade-off - lower quality = smaller file. At medium quality, most compression is imperceptible.
What formats are supported?▼
Input: MP4, WebM, MOV, AVI, and other formats your browser supports. Output: WebM (for browser compatibility). The Pro version supports MP4 output via ffmpeg.
Is my video uploaded to a server?▼
No - compression uses the MediaRecorder API in your browser. Your video never leaves your device. Large videos may take longer to process on older devices.
How much can the file size be reduced?▼
Typically 40-80% reduction depending on the original quality and your chosen settings. A 100MB video can often be compressed to 20-40MB with minimal visible quality loss.
