FAQ
How much can I reduce the file size?
The reduction depends on your settings. Low quality with 360p resolution at 15 fps can reduce size by 80-95%. High quality at original resolution may see 10-30% reduction. Results vary by content.
What codec is used for compression?
The tool uses your browser's MediaRecorder API, typically using VP8 or VP9 codec for WebM output. Chrome also supports H.264 for MP4 on some systems.
Is the compression lossy?
Yes, all compression options are lossy. The video is decoded and re-encoded, which always introduces some quality loss. Choose 'High' quality to minimize visible degradation.
