Convert MP3 to WAV online
Turn MP3 files into uncompressed WAV audio that every editor and DAW accepts. Convert one file or a whole batch in your browser, with nothing uploaded.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
Why convert MP3 to WAV?
WAV is uncompressed, so editing software can read and cut it without decoding it first. It is the format most video editors, DAWs, broadcast workflows and sample libraries expect, and it will not lose anything more when you export again.
Expect a larger file
A WAV is often around ten times the size of a 128 kbps MP3 because it stores every sample. Choose mono or a lower sample rate if you need to keep the file smaller.
FAQ
Does converting MP3 to WAV improve the sound?
No. A WAV keeps exactly what is in the MP3, but it cannot restore the detail MP3 compression has already removed.
Which sample rate should I pick?
Keep leaves it as it is. Choose 48 kHz for video projects and 44.1 kHz for music.
Is my MP3 uploaded?
No. It is decoded and rewritten inside this browser tab.
What can you do with an audio converter?
Editors turn phone recordings into WAV files that every timeline accepts; podcasters export a small MP3 from a large master; musicians archive takes as lossless FLAC; and anyone stuck with a file a device refuses to play can switch it to a format that works everywhere.
