Convert MP3 to WAV
Convert MP3 files to uncompressed WAV format directly in your browser. WAV is the standard format for audio editing in DAWs like Audacity, Pro Tools, and Logic Pro — no compression artefacts during further processing. No upload needed.

When to Convert MP3 to WAV
- Converting MP3 tracks to WAV for import into Ableton Live or Logic Pro for remixing without decode-on-playback overhead
- Preparing MP3 voice recordings as WAV for editing in Audacity with no further generational loss
- Converting MP3 samples to WAV for loading into hardware samplers like the MPC Live or Akai Force
- Rendering MP3 podcast episodes to WAV for mastering passes in iZotope RX before final delivery
- Converting MP3 stems to WAV for use in multitrack video editors like Premiere Pro or DaVinci Resolve

How It Works
Drop your MP3 files
Drag and drop or select MP3 files at any bitrate (CBR or VBR) and sample rate. First use loads FFmpeg WASM (~30MB).
FFmpeg decodes MP3
FFmpeg WASM parses the MPEG audio frames and decodes the Huffman-coded data back to raw PCM samples at the source sample rate. Everything runs locally.
Write 16-bit PCM WAV
PCM samples are written as uncompressed 16-bit signed PCM with a RIFF WAV header at the source sample rate (typically 44.1kHz).
Download your WAV files
Your uncompressed WAVs are ready for any DAW, sampler, audio editor, or video editing tool.
// under the hood
MP3 uses MPEG-1/2 Layer 3 lossy compression with psychoacoustic masking and Huffman coding. Our converter uses FFmpeg WASM with the libmp3lame-compatible mpg123 decoder to decompress the MP3 to raw PCM samples at the source sample rate. The samples are then written to a WAV file as uncompressed 16-bit signed little-endian PCM, stereo, with a standard RIFF WAV header. No further quality loss occurs during the WAV write.

Frequently Asked Questions
- Why convert MP3 to WAV?
- DAWs and audio editors work most reliably with uncompressed PCM. Loading an MP3 into Pro Tools, Logic Pro, or Audacity triggers a decode every time you scrub or render — converting to WAV up front gives you a stable, editable file with zero further quality loss during processing.
- Does WAV restore the audio quality?
- No — WAV cannot recover information lost during the original MP3 encoding. The MP3 codec discards inaudible data permanently. Converting to WAV gives you a perfectly preserved decode of the lossy MP3, but the source quality is the ceiling. WAV is about preventing future quality loss, not restoring past loss.
- What's the WAV file size?
- Roughly 10 MB per minute of stereo audio at 44.1kHz/16-bit. A typical 4-minute song becomes a ~40 MB WAV vs a ~4 MB MP3. WAV is uncompressed — every sample is stored at full precision. That's why it's the editing format, not the delivery format.
- What sample rate and bit depth?
- We decode MP3 at its native sample rate (typically 44.1kHz for music, 22.05kHz for some podcasts) and write 16-bit signed PCM stereo WAV. This matches CD quality and is the standard format expected by virtually every audio tool.
- Are my MP3s private?
- Yes. FFmpeg WebAssembly runs entirely in your browser. Your MP3 files never leave your device — no upload, no server, no logging.
