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.
