Yes, completely free to use. No registration, no login required. All features are available directly. No file size limits, no watermarks.
No. All video compression is done locally in your browser. Files are never uploaded to any server, fully protecting your privacy. Works even offline.
Supports importing MP4, WebM, MOV, AVI and other common video formats. Output format depends on browser support, typically WebM (VP9) or MP4 (H.264).
Video compression is lossy, so quality will decrease somewhat. You can balance file size and quality using the compression quality slider. We recommend starting with 0.6-0.8 quality.
Compression speed depends on video size and your computer performance. Try lowering the resolution or trimming the video to speed things up. Videos under 5 minutes work best.
