About converting MP3 to WAV
Converting MP3 to WAV decodes the audio and re-encodes it to WAV entirely in your browser. MP3 is small and universally playable; WAV is uncompressed and lossless.
Your audio never reaches a server. Converting an already-compressed file to a lossless format can't restore detail that was removed earlier.
Editors, DAWs and samplers often want uncompressed PCM rather than MP3, and WAV is that: this tool decodes your MP3 and writes it as 16-bit PCM WAV. No quality is gained — the audio is the same, just unpacked — and the file grows to roughly 10 MB per stereo minute, which is the price of universal editing compatibility.
Frequently asked questions
How do I convert MP3 to WAV?
Add your MP3 file above and press Convert. FileTinker decodes and re-encodes it to WAV in your browser, then gives you the converted file to download — nothing is uploaded.
Is my audio uploaded to convert MP3 to WAV?
No. The conversion runs entirely in your browser, so your audio never leaves your device and nothing is stored on a server.
Will converting change the audio quality?
WAV is uncompressed and lossless, while MP3 uses efficient compression at a high-quality bitrate. Converting an already-compressed file won't restore detail that was removed earlier.
Can I convert several files?
Convert them one after another — each runs locally and downloads instantly, with no queue, sign-up or file-size limit.
Does converting MP3 to WAV improve the sound?
No — WAV just stores the already-decoded MP3 audio without further compression. Quality lost when the MP3 was made is gone for good. Convert when a program or device insists on WAV, not in the hope of restoring fidelity.
