Frequently Asked Questions
How do I convert MP3 to WAV?
Load your MP3 file, click Export, and choose WAV as the output format. The file is decoded and saved as uncompressed WAV audio without any upload - everything happens in your browser.
How do I convert WAV to MP3?
Load your WAV file, click Export, choose MP3, and pick a bitrate (128-320 kbps). At 320 kbps the result is virtually indistinguishable from the original for most listeners.
Which formats can I convert from?
You can load MP3, WAV, OGG, AAC, FLAC and M4A files. Output can be MP3 or WAV, so you can convert any of these formats to either.
MP3 or WAV - which should I choose?
Choose WAV for maximum quality and further editing (it is uncompressed). Choose MP3 for smaller files that are easy to share and play everywhere, for example on phones or in messaging apps.
Is my audio uploaded to a server?
No. The conversion runs entirely in your browser using JavaScript. Your files never leave your device, so even long recordings convert quickly and privately.
Can I cut only part of the file?
This page converts entire files. If you want to extract just a segment of a song or recording, use the main audio cutter on the homepage - it supports the same formats and also exports MP3 and WAV.
