Common mistakes
- Uploading a video file too large for the browser (keep it under 2 GB).
- Closing the tab before processing finishes: the conversion stops.
- Using an exotic input format (prefer MP4, WebM, MOV, AVI).
- Picking a bitrate so low that quality drops noticeably.
Pro tips
- Pick H.264 (MP4) for the widest compatibility.
- For the web, use WebM (VP9/AV1): smaller file at the same quality.
- Keep the original: processing is local but the download is final.
- On mobile, plug in the charger for long videos.
Privacy guaranteed
Your videos are processed locally. No files are uploaded.
Adjust bitrate — Mbps, kbps, CBR, VBR
Control your video bitrate (measured in Mbps or kbps) to balance file size and image quality. Choose between CBR (constant bitrate) or VBR (variable bitrate) mode, optimize encoding for streaming, reduce bandwidth usage and tune the output without degrading playback.

Technical details
