MP3 to WAV
Convert an MP3 audio file to WAV format without additional quality loss.
How to convert MP3 to WAV online and free
Upload your MP3 file
Drag and drop your MP3 file, or click to select it from your computer or mobile device.
Wait for the conversion
The first time, your browser downloads the conversion engine (a few extra seconds); then the audio converts directly on your device, with nothing uploaded to a server.
Download your WAV file
Press the conversion button and download the resulting WAV file directly to your device.
Why convert MP3 to WAV on PDFDocks?
WAV is an uncompressed audio format, widely used in professional audio editing and in programs that don't directly support MP3. PDFDocks converts your file directly in your browser, without uploading it to any server.
Is it safe to convert MP3 to WAV online with PDFDocks?
+
Yes. Your audio file is never uploaded to a server: the conversion happens directly in your browser.
Why does the first conversion take longer than the following ones?
+
The first time you use this tool, your browser has to download the conversion engine (a component of several megabytes). Once downloaded, your browser caches it and subsequent conversions are faster.
Does audio quality increase when converting to WAV?
+
No. WAV has no compression, but it cannot "recover" information that was already lost when creating the original MP3 — it simply stores the same audio uncompressed.
Do I need to install any software?
+
No, there's no need to install anything. It works directly from your browser, although you'll need to download the conversion engine the first time you use it.
Is there a file size limit?
+
We haven't set any artificial limits. The only real constraint is your device's memory and processing power — very large files may take longer to convert.
Does it work on mobile?
+
Yes, though on mobile devices with less memory the conversion may be slower than on a computer.
