How do I convert an audio file?
- 01
Choose your file
Add audio from your device. Each file can be up to 40 MB and 10 minutes long. Only use files you have permission to convert.
- 02
Set your export
Choose MP3, WAV, OGG, FLAC, M4A or AAC. MP3 and AAC offer bitrates from 128 to 320 kbps.
- 03
Save your audio
Wait for processing to finish, then download your file. Conversion uses your device, so keep this tab open.
Your audio stays on your device
Conversion runs in your browser. Your file is not uploaded to MyBeatz, published or added to a library. The engine downloads on first use, which can take a moment. No account or MyBeatz credits are required.
Choose your audio export settings
Choose MP3 to share your sounds, WAV to import them into music software, or FLAC for compatible audio archives. Exports use stereo at 44.1 kHz; WAV and FLAC use 16-bit audio. Tags and cover art are not retained. Keep your original file for future projects.

Frequently asked questions
Why choose AAC?
AAC is a lossy codec. This export produces an ADTS file rather than an M4A container, at 128, 192 or 320 kbps. If your application needs M4A, use the M4A converter instead of renaming an AAC file.
Does this really convert the audio?
Yes. The signal is decoded and encoded into the selected format. The tool does not simply change the file extension.
Why convert MP3 to WAV?
WAV is widely supported by music production and audio editing software. Convert your MP3 to WAV to prepare a track for your session, with a 16-bit stereo PCM export at 44.1 kHz.
Why is conversion slower on my phone?
Processing uses your device’s CPU and memory. Close other tabs, keep this one in the foreground and try a shorter file if necessary. Processing stops after three minutes.
Can I convert a Spotify or YouTube link?
No. This tool accepts local files only. It does not download music from platforms or remove DRM protections.
