Pull the soundtrack out of a video file
Upload a video (MP4, MOV, MKV, AVI and WebM are the usual cases) and save its audio track as MP3, WAV, OGG or M4A. The video previews in the page with its duration and file size, you pick the format, and the extracted audio appears in a player with a filename field before you download it.
The audio is decoded and re-encoded into the format you choose rather than copied byte for byte. MP3 is written at the encoder's highest variable-bitrate quality setting, M4A uses AAC, OGG uses Vorbis, and WAV is uncompressed PCM, so it is the largest file and the one that adds no further compression loss. For podcasts, lectures and voice memos MP3 is the sensible default; use WAV if the audio is going into an editor.
Extraction is done by FFmpeg compiled to WebAssembly, which the page fetches from a CDN when it loads. The video file itself is only ever read into your browser's memory, so a long recording of a private meeting is handled as privately as it would be on your own machine. Progress is shown as a percentage, and a video without an audio track produces an error rather than a silent file.
Frequently asked questions
Does it work with any video file?
It needs a video with an audio track. The in-page preview may stay blank for formats your browser cannot play, such as some MKV or AVI files, but extraction still runs on them.
Is there a file size limit?
No fixed limit. The file is loaded into browser memory, so very large recordings can fail on devices with little RAM; trimming the video first helps.
Which format should I choose?
MP3 for anything you will listen to or share, M4A if the destination prefers AAC, OGG for Vorbis-based workflows, and WAV when the audio is going into an editor and size does not matter.
Does extraction keep the original audio quality?
The track is decoded and re-encoded. WAV keeps everything the decoder produced; MP3, M4A and OGG are lossy, with MP3 written at the encoder's highest quality setting.
Is the video uploaded?
No. The FFmpeg engine comes from a CDN, but the video stays on your device throughout.
Can I convert a video to MP3 with this?
Yes. Choose MP3 as the output format and the audio track of the video is saved as an MP3 file; WAV, OGG and M4A are also available.
