Frequently Asked Questions
Does the video compressor upload my video to a server?
No. Video compression happens entirely in your browser using the browser's built-in MediaRecorder API. Your video never leaves your device.
What video formats does the compressor support?
The compressor supports MP4, WebM, and most common video formats that your browser can natively play. Output is typically in WebM format for best compression.
How much will my video file size be reduced?
Compression ratio depends on the original video quality and selected settings. You can typically reduce file size by 40–80% without noticeable quality loss.
Is there a video size limit for compression?
There is no hard limit, but large videos (over 1 GB) may require significant RAM and processing time. We recommend compressing videos under 500 MB for best performance.
