How to use the audio to MP3 converter
- Choose one or more audio files — WAV, M4A, AAC, OGG, Opus, FLAC, AIFF or WebM.
- Pick the MP3 quality (192 kbps is a good default) and mono if it is speech.
- Each file is converted on your device; listen to it and download the MP3.
MP3 plays on every phone, car stereo, smart speaker and old MP3 player. Converting WAV or FLAC to 192 kbps MP3 makes files about 7× smaller with quality most people cannot tell apart; 96–128 kbps mono is perfect for voice memos, lectures and podcasts. The encoder (LAME) runs in your browser, so music and recordings are never uploaded.
FAQ
Which bitrate should I choose?
128 kbps is fine for speech and casual listening, 192 kbps for music, 320 kbps if you want the best MP3 quality. Higher bitrates make bigger files.
Does converting improve quality?
No — converting a low-quality file to a higher bitrate only makes it bigger. Use the original WAV or FLAC for best results.
