Frequently Asked Questions
How much can videos be compressed?
Compression varies by video content, but typical reductions are 50-80%. Videos with lots of motion compress less than static content.
Will I lose video quality?
Some quality loss is inevitable with compression. Use "High quality" preset for minimal loss, or "Small file" if size matters more than quality.
Is my video data private?
Yes, 100% private. All compression happens locally in your browser using FFmpeg.wasm. Your video is never uploaded anywhere.
What video formats are supported?
Input supports MP4, WebM, MOV, AVI, MKV and more. Output is always MP4 (H.264) for maximum compatibility.
Why is processing slow for large videos?
Video processing is computationally intensive. Browser-based processing is slower than native apps. For very large videos, consider using desktop software.
What is the maximum file size?
We support videos up to 500MB. Larger videos may work but could cause memory issues depending on your device.
