Common questions

Will converting audio reduce the quality?
Lossy-to-lossy conversions (like M4A to MP3) involve a small re-encoding step. We default to 192 kbps for MP3 output — perceptually transparent for almost all listeners. Lossless formats (WAV, FLAC) preserve quality exactly.
Can I extract audio from a video file?
Yes. Drop an MP4, MOV, or MKV onto the MP4 to MP3 converter and it extracts the audio track directly — no video re-encoding needed.
What's the most compatible audio format?
MP3 plays on every device and app without exception — car stereos, Android, iOS, web browsers, game consoles. If compatibility is the goal, MP3 at 192 kbps is the safest bet.
