Drop MP3 files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Save the WAV, or download everything as one ZIP if you converted several files.
The MP3 to WAV converter is part of this page and runs inside your browser. Your audio files are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
Some audio editors, samplers, phone-system and broadcast tools, and CD-burning software want WAV. Converting gives them a file they accept. It does not restore what MP3 compression removed: the WAV is the same sound in a container about ten times larger.
The defaults suit most files. Under Options you can trim the start and end.
The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine.
MP3 is the audio format everything plays. It shrinks audio to roughly a tenth of its uncompressed size by discarding sound most listeners cannot hear. Newer codecs are more efficient, but nothing matches its compatibility.

No. The detail MP3 discarded is gone. The WAV is an exact, uncompressed copy of what the MP3 plays.
No. The MP3 to WAV conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Nothing more is lost: WAV is uncompressed, written as 16-bit audio, the same as a CD. It cannot restore what MP3 compression already discarded, and the file will be larger.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MP3 file, press Convert and save the WAV. There is nothing to install.
Yes. Files up to 2 GB are accepted. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
