Video → MP3
Über dieses Tool
Pull the audio track out of any video file and save it as a clean MP3. Perfect for grabbing a song from a clip, archiving the spoken dialog from a meeting recording, prepping a podcast version of a video interview, or making an audio-only copy of a lecture for the train.
Privvert's audio extractor accepts MP4, MOV, MKV, WebM, AVI, FLV and most other common containers. The extraction runs in your browser via FFmpeg-WebAssembly, so the source video - and any private content in it - never travels over the internet.
Behind the scenes the audio is decoded from the container's audio track (AAC, Opus, Vorbis or AC-3 in most cases) and re-encoded to a constant-bitrate MP3 with a LAME-style encoder running in WebAssembly. Multi-channel layouts are downmixed to stereo so the output plays correctly on any phone, car stereo or smart speaker.

Yes - the original audio (often AAC inside MP4 or Vorbis inside WebM) is decoded and re-encoded to MP3 at 192 kbps. That means the output is always a standard MP3 file that plays everywhere.
There's a single generational re-encode. At 192 kbps the difference from the source is inaudible to most listeners on most material.
Extract first, then use the audio trim tool to cut the section you want.
The tool will tell you no audio stream was found - there's nothing to extract.
MP3 at 192 kbps is the lowest-friction format - every player, every car, every podcast app handles it. If you need a lossless intermediate for further editing, convert the MP3 to WAV afterward or use the video convert tool to keep AAC.
Yes - the output is audio only. Chapter markers, subtitle tracks and embedded thumbnails are not carried over. See the format-choice guide for related thinking about which metadata travels with which formats.
