How to convert audio to MP3
Use this audio to MP3 converter when a player or messaging app does not accept your recording’s format. For a voice note, try 96 or 128 kbps; for music, start at 192 kbps and listen before choosing a larger file. An existing MP3 can also be re-encoded, but another round of compression can lose more detail.
- Audio in
- Common WAV, M4A, FLAC, OGG, and MP3 recordings. Unusual encodings may need a standard export from the original app.
- Audio out
- MP3; 64–320 kbps at 44.1 or 48 kHz. At 16 or 22.05 kHz, the maximum is 128 kbps.
- Sharing
- Choose mono for a voice-only recording when appropriate. Music usually benefits from keeping stereo.
Select audio from your device, or try the WAV sample before using your own recording.
Keep MP3 selected. Choose a bitrate, and change sample rate or channels only if needed.
Convert audio to MP3, listen to the result, and download each finished file.
Listen to a real WAV to MP3 example
This short, synthetic recording says: “The meeting starts at nine. Please bring your notes.” The result below was made with this tool. Compare the sound and size, or try the sample above with your own settings.
The MP3 is smaller than this uncompressed WAV. The original is kept separately. MP3 players may show a slightly different length because of audio padding. These sizes describe this sample only. Duration, source audio, format, and settings change your result; a smaller file is not a measure of better sound.
Audio to MP3 questions
Which bitrate should I choose for audio to MP3?
96 or 128 kbps is a useful starting point for speech. Start at 192 kbps for music, or try 256 or 320 kbps if you prefer a larger file. Listen to the result: the best choice depends on the source and how you will use it.
Does converting audio to MP3 improve its quality?
No. MP3 is lossy. A higher bitrate cannot recover missing detail, and re-encoding an already compressed recording may introduce additional loss. Keep your best original recording.
Can this make an MP3 fit a specific size limit?
A lower bitrate usually reduces size, but this tool does not target an exact file size. Compare the input and output sizes beside the finished file. Remove the finished item and convert the original again at a lower bitrate if needed.
Can I convert several files at once?
Add up to 10 files. They are processed one after another, and you can download each finished result or save the batch in one ZIP. Each file can be up to 100 MB, or 25 MB on touch devices. Use a computer for larger recordings.
Where is my download, and what happens to the original?
Choose Download beside a finished file. Look in your browser’s Downloads or the Files app on your phone; some browsers offer a sharing menu. The original is unchanged. Results are kept only in this tab, so download them before refreshing or leaving.
