WAV Converter

Convert MP3, FLAC, OGG, M4A, AAC, MP4, or MOV to uncompressed WAV — or export WAV to a compressed format for sharing. Runs in your browser. No upload.

About the WAV Format

WAV (Waveform Audio File Format) stores uncompressed PCM audio — raw digital samples taken directly from an analog-to-digital converter, with nothing encoded or discarded. Developed by Microsoft and IBM in 1991, it has been the editing standard in professional audio ever since. Every DAW on every platform accepts it without conversion or plugins.

At 16-bit, 44.1 kHz, a WAV file is CD quality and runs about 10 MB per minute. At 24-bit, 48 kHz — broadcast standard — expect roughly 17 MB per minute. The trade-off is file size: a 4-minute song that is 4 MB as an MP3 becomes 40–70 MB as WAV. That is the price of having every sample intact.

WAV is the right choice when you are editing (import into your DAW, apply effects, export), archiving a high-fidelity recording, or burning to CD. For sharing or streaming, compress to MP3 or FLAC — but keep the WAV as your working master.

When WAV Is the Right Choice

Importing into a DAW

Pro Tools, Logic Pro, Ableton Live, Reaper, and FL Studio all accept WAV natively. It is the universal currency of professional audio.

CD burning

Red Book CD standard requires uncompressed PCM at 44.1 kHz — exactly what WAV provides. MP3 cannot be burned directly to an audio CD.

Re-processing audio

Applying EQ, compression, or normalization to a lossy file re-encodes it, compounding artifacts. Work from WAV to avoid generation loss.

Sound design and game audio

Unity, Unreal Engine, and most game engines default to WAV for in-game audio assets. Game audio middleware (FMOD, Wwise) also expects WAV as the source.

Mastering and stem delivery

Mastering engineers and distributors request 24-bit WAV or AIFF stems. Export your tracks as WAV before sending for professional mastering.

Why Use AudioUtils for WAV Conversion

AudioUtils runs FFmpeg compiled to WebAssembly directly in your browser — your audio files never leave your device, which matters when you are working with unreleased music, client recordings, or anything you would not want passing through a third-party server. There are no upload queues or file-size limits on speed: conversion starts the moment you select a file. The core converter is free with no account required; Pro unlocks full-length output for $9/month.

Frequently Asked Questions

Is the WAV output lossless?

It depends on your source. Converting FLAC or WAV to WAV is fully lossless. Converting MP3 to WAV produces an uncompressed PCM file, but the audio quality is still limited by the original MP3 — lossy data cannot be recovered by changing the container.

What sample rate and bit depth does the WAV output use?

16-bit PCM at the source file's sample rate — typically 44.1 kHz for music and 48 kHz for video audio. This matches CD quality and is what every DAW expects by default.

Is this WAV converter free?

Yes, free with no account required. The free tier outputs a 30-second preview. Pro ($9/month) unlocks full-length conversions and files up to 500 MB.

Do my files get uploaded to a server?

No. AudioUtils runs FFmpeg compiled to WebAssembly entirely in your browser. Your files never leave your device — we never see them, store them, or log them.

Which DAWs accept the WAV output?

All of them: Pro Tools, Logic Pro, Ableton Live, Reaper, FL Studio, GarageBand, Audacity, Adobe Audition — standard RIFF WAV with PCM data is the universal DAW format.
