About this tool
Choose "Keep original codec" to get an M4A or Opus file that contains the exact audio from the video — finished in seconds, no quality loss. Choose MP3 or WAV when the destination needs it; that path decodes and re-encodes in your browser using the LAME encoder. Works with hour-long recordings.
Questions
- Which video formats work?
- MP4, MOV, WebM and MKV. AVI, WMV and FLV are not readable in a browser yet; convert them on your computer first.
- Is the quality reduced?
- Trim and Mute copy the original video packets, so quality is identical. Convert and Compress re-encode using the codecs built into your browser.
- Why is there a size limit?
- Files up to 500 MB are free; browser memory is the real ceiling. Plus raises the limit to 4 GB.
