Convert images, documents, video and audio in your browser. Your files stay on your device.
Go from MP3 to WAV without installing software: the conversion runs on your device and the files aren’t uploaded anywhere.
Drag one or more MP3 files onto the dashed area, or tap it to pick them from your device.
WAV is already selected: you can adjust bitrate, channels and volume, and trim the track.
Press “Convert to WAV”. When it’s done, download the files one by one or all together in a ZIP archive.
Good to know. Converting a compressed file to a lossless format won’t bring back lost quality, but it avoids further losses when you edit it later.
Source format
MPEG-1 Audio Layer III
The audio format that changed music: a four-minute song weighs a few megabytes. Any player, car stereo or phone built in the last twenty years plays it.
Target format
Waveform Audio File Format
Uncompressed audio: every sample is stored as it is. It’s the working format of recording studios and editing software, perfect for editing but very heavy.
Audio and video use WebCodecs: they work in up-to-date Chrome, Edge, Opera and Samsung Internet, in Firefox 130+ and Safari 17+ (with a few limits on the formats they can create). If your browser can’t create the chosen format, we tell you before you start.
No. The conversion from MP3 to WAV happens entirely in your browser, using your device’s computing power. Files aren’t sent or stored anywhere: when you close the page they’re gone from memory too.
Up to 100 files at a time. There’s no fixed size limit: it depends on your device’s memory. On smartphones it’s best to work in smaller batches with heavy files such as videos.
Yes, with up-to-date Safari, Chrome, Firefox, Edge and Samsung Internet. On phones, converted files end up in the Downloads folder or the Files app.
Only to open the page (and, the first time, to download the components needed for that type of file). After that the conversion keeps working even if the connection drops.
