convert mp3 to wav
Drop the MP3, pick WAV and select 16, 24 or 32 bits. The estimated size shows before converting. The MP3 sample rate is kept, with no resampling to the sound card rate, and the result is written as plain PCM.

Input is whatever your browser can decode: MP3, WAV, OGG, OPUS, FLAC, M4A, AAC and WEBM audio, plus the audio track of MP4 and WEBM videos. Output is MP3, WAV, FLAC, OGG Opus and M4A (AAC). The last two depend on the browser's encoder, and the screen tells you when one is missing.
No. It reproduces exactly what the MP3 decodes to, without recovering what was discarded. The advantage is that you can edit and save again without adding a new lossy compression.
For listening or delivering, 16 bits. To keep editing, 24 bits give more headroom. 32-bit float is well supported in professional editors, but some simple programs do not open it.
Because resampling without need only adds processing. The tool reads the rate from the header and keeps it. If you need another, for example 48 kHz for video, choose it under Sample rate and the audio is resampled by a sinc filter.
MP3 is written at a constant bitrate (CBR), the same across the whole file.
Conversion happens in your browser. No file is sent to a server.
