Frequently Asked Questions

This tool supports MP4 (.mp4), QuickTime (.mov), AVI (.avi), Matroska (.mkv), and WebM (.webm) video files. These cover the vast majority of videos from cameras, screen recorders, and downloaded content.

MP3 is the most universally compatible format — it plays on virtually every device and software. AAC offers slightly better audio quality at the same bitrate and is preferred for Apple devices. WAV is a lossless, uncompressed format producing the highest possible quality but with much larger file sizes. Use MP3 for general use, AAC for Apple ecosystems, and WAV when audio quality is critical.

For MP3 and AAC, some quality loss occurs due to lossy compression — but at 128 kbps or higher it is generally imperceptible during normal listening. Selecting WAV output preserves the original audio data without any loss. The "High (192 kbps)" setting produces near-transparent quality for most audio content.

Yes, there is no hard file size limit. However, very large files (over 200 MB) require more browser memory and conversion time. FFmpeg.wasm processes the entire file in RAM, so available system memory is the practical constraint. For very large files, we recommend using a desktop application like HandBrake or VLC.

No. This tool uses FFmpeg.wasm — a WebAssembly port of FFmpeg — which runs entirely inside your browser. Your video file never leaves your device. No data is sent to any server at any point during the conversion process.
