About Audio converter
The audio converter turns an audio file into a different format on your own device. Open any file your browser can play, such as MP3, AAC, M4A, Ogg, Opus, FLAC or WAV, check its details, and save it again in the format you need.
WAV export works in every modern browser and gives uncompressed 16-bit audio at the sample rate you choose, in stereo or mixed down to mono. Compressed formats use the browser’s built-in recorder, so the choices you see depend on your browser.
How to use it
- Choose or drop an audio file of up to 50 MB and 20 minutes.
- Pick the output format. For WAV, choose a sample rate and whether to mix it to mono.
- Press Convert, then preview and download the result.
Good to know
- Input is limited to 50 MB and 20 minutes. Files the browser cannot decode, such as some ALAC or WMA files, cannot be opened.
- MP3 export is not available. WebM and Ogg (Opus) or M4A (AAC) appear only when your browser can record them.
- Compressed formats are recorded in real time, so converting a 4-minute song to WebM takes about 4 minutes. WAV export is much faster.
- Tags such as title, artist and cover art are not copied to the new file.
Questions and answers
Which output formats can I use?
16-bit PCM WAV always works. Chrome and Edge usually offer WebM (Opus), Firefox offers Ogg and WebM (Opus), and Safari offers M4A (AAC). The format menu lists only what your browser supports.
What sample rate should I pick?
44.1 kHz suits music and CDs, 48 kHz suits video, and 16 kHz is common for speech tools and transcription. Going higher than the original does not add detail.
Why is the WAV file so large?
WAV is uncompressed: one minute of 44.1 kHz stereo is about 10 MB. Choose mono or a lower sample rate for smaller files, or a compressed format if your browser offers one.
