Drop any audio file (WAV, M4A, OGG, OPUS, FLAC, WMA, AMR, AIFF and more, up to 100 MB) and you get an MP3 that plays everywhere. A lossless WAV or FLAC is encoded at 192 kbps; a small voice recording stays small. No account, no ad.
Why use Audio to MP3?
Files that will not play
AMR from an old phone, OPUS from a chat app, CAF from a Mac, WMA from Windows: MP3 plays in every car, browser and editor.
WAV and FLAC, much smaller
A CD-quality WAV uses about 1,400 kbps, so a 192 kbps MP3 is about 7 times smaller. A FLAC shrinks less, about 3 to 5 times. On speech and pop music most listeners hear no difference.

Interviews, voice memos and lectures can go straight to text from the result: the first 30 minutes are free without an account.
How it works
Drop the audio file
Any common format, up to 100 MB.
Convert to MP3
We read the recording's bitrate and encode the MP3 to match, up to 192 kbps.

Which bitrate will my MP3 have?
It follows your recording
Re-encoding at a much higher bitrate than the source adds size, not sound. Encoding a rich source too low loses detail. We leave a margin above the source and stop at 192 kbps.
| Your recording | MP3 you get |
|---|---|
| WAV, FLAC, AIFF (lossless) | 192 kbps |
| M4A, AAC, OGG at 128 kbps or more | 192 kbps |
| Audio around 96 kbps | 128 kbps |
| Voice notes and calls around 24 to 48 kbps | 64 kbps |

WAV, M4A, AAC, OGG, OPUS, OGA, FLAC, WMA, AMR, AIFF, CAF and WebM audio, plus the sound of a video file.
MP3 is lossy, so it is not a bit-for-bit copy. At 192 kbps most people cannot hear a difference on speech or popular music. Keep the WAV if you will edit or master the audio.
