MP3 to WAV Converter
Convert MP3 to uncompressed WAV for editing in a DAW or audio tool, free and entirely in your browser.
What is MP3?
MP3 is a lossy, compressed audio format — great for playback and sharing, but the compression is a one-way trip; some audio detail is permanently discarded when it’s encoded. It’s rarely the format professional audio tools expect as input.
Why convert MP3 to WAV?
WAV is the uncompressed format most audio editors, DAWs (Audacity, Pro Tools, Logic), and some hardware samplers expect, since it avoids re-compression artifacts during editing and decodes instantly without CPU overhead. Converting MP3 to WAV is the standard prep step before editing, mixing, or importing audio into professional software.
How to convert MP3 to WAV
- Drop your MP3 file. Drag and drop a MP3 file, or click to browse. First use loads the ffmpeg.wasm engine (~31 MB, cached in your browser after).
- Confirm output is WAV. This page pre-selects WAV as the output format — change it in the format picker if you’d rather export something else.
- Set quality and convert. Pick a quality or bitrate preset, then click Convert. Processing runs locally on your device and typically finishes in well under a minute for short files.
- Download. Click Download to save your WAV file. Nothing was ever uploaded to a server.
Your file never leaves your browser — conversion runs locally via ffmpeg.wasm, not on a server.
Use Cases
- Import an MP3 track into a DAW or audio editor that expects WAV
