Frequently Asked Questions
?How does the video compressor work?
The tool uses FFmpeg WebAssembly technology to re-encode videos with optimized settings entirely in your browser. No files are uploaded to any server.
?Will the video quality be affected?
Some quality reduction is inherent in compression, but the high-quality preset minimizes visible differences. You can choose between file size and quality.
?What compression ratios can I expect?
Typical compression ratios range from 30% to 80% reduction depending on the source video and quality settings. Already compressed videos will see smaller reductions.
?What video formats are supported?
The tool supports MP4, MOV, AVI, MKV, WebM and most other common video formats. Output is always MP4 for maximum compatibility.
?How long does compression take?
It depends on the file size, duration and your device's processing power. A 1-minute video typically takes 15-45 seconds.
?Is there a file size limit?
There's no hard limit, but very large files (over 500MB) may be slow to process since everything runs in your browser's memory.
?Is my data private?
Absolutely. Your video files never leave your device. All compression happens locally using WebAssembly technology.
?Is this tool free?
Yes, it is completely free with no sign-up, no watermarks, and no limits.
