Video to MP3 (extract audio online)
Sometimes you only want the sound: listen to a lecture like a podcast, keep a piece of background music, save an interview. Video-to-MP3 lifts the audio track out and saves it. Because it only touches the sound, it's far faster than compressing the whole video. Use the tool above.
Quick answer
The fastest way to save a video's sound as MP3 is to decode only the audio track and skip the picture. ConvertMeow does it locally in your browser — MP4/MOV/MKV/WebM, never uploaded, no cap, no watermark — for turning lectures into podcasts, lifting background music or keeping interview audio.

Why is extracting audio so fast?
Compressing video re-encodes every frame, which is the slow part; extracting audio decodes only the audio track and drops the picture, which is far less work — so it's quick.
ConvertMeow exports MP3 at 192kbps by default, virtually transparent for speech, lectures and podcasts; pick 256/320kbps for higher quality.
When should I choose WAV over MP3?
If you'll re-edit, mix or further process the audio, export WAV (lossless) in the audio converter instead, to avoid stacking lossy on lossy and degrading quality. For plain listening, MP3 is fine.
Frequently asked questions
MP4, MOV, MKV, WebM, AVI and other common containers can have their audio read and converted to MP3. Very rare codecs may fail — convert the video to MP4 first if so.
No. ConvertMeow only works on video files already on your computer; it doesn't download or scrape video from any site. Use footage you own or have the rights to.
No. The whole extraction runs locally in your browser with ffmpeg — neither the video nor the audio leaves your device.
