Audio to WAV Converter

Convert Audio to WAV Online

Turn almost any audio file into an uncompressed WAV — MP3, AAC, M4A, M4B, FLAC, OGG, Opus, WMA, AC3, AMR, AIFF, AU, OGA, WebA, VOC, DSS, and more all decode to standard PCM WAV. WAV is the format pro tools, DAWs, samplers, and older hardware expect, so this is the conversion you reach for when a file needs to open somewhere rather than stay small. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.

How to Convert Audio to WAV

1. Upload Your Audio File: Drag and drop your file onto the page or click "Add Files." You can queue several files and convert them in one batch.
2. Pick the Audio Codec: WAV defaults to PCM 16-bit Little Endian (CD quality). Open Advanced Options to switch to PCM 24-bit or 32-bit for studio masters, or A-law / mu-law for telephony.
3. Set Channel and Sample Rate (Optional): Leave Audio Channel and Audio Sample Rate on "Original" to copy the source, or force Mono / Stereo and a fixed rate like 44100 Hz or 48000 Hz for a target device.
4. Convert and Download: Click "Convert" and save your WAV. No sign-up, no watermark.

WAV vs. Your Source Format

Frequently Asked Questions

Does converting MP3 to WAV improve the sound quality?

No. MP3, AAC, and Opus are lossy — encoding permanently discards audio data, and that data cannot be rebuilt. Converting to WAV re-wraps the already-reduced audio as uncompressed PCM, so it sounds the same as the MP3, just in a larger, edit-friendly file. WAV is worth it for compatibility and editing, not for a quality boost. To genuinely improve quality you have to go back to a higher-bitrate or lossless original.

Which PCM bit depth should I choose — 16-bit, 24-bit, or 32-bit?

PCM 16-bit Little Endian is CD quality and the safe default for playback and sharing. Choose 24-bit if you're importing into a DAW for mixing and want headroom for processing, which is the studio standard. 32-bit (float) is mainly useful as an intermediate format while editing, where it prevents clipping during gain changes. For a lossy source there's no benefit to going above 16-bit — the extra depth only adds file size, not detail.

Why is my WAV file so much larger than the original?

WAV stores raw, uncompressed PCM samples, so size is fixed by sample rate, bit depth, and channels rather than by the audio content. A 44.1 kHz, 16-bit, stereo file runs about 10 MB per minute regardless of whether it's music or silence. In our testing, a 3-minute 192 kbps MP3 of roughly 4 MB became a ~30 MB WAV. If you need the file small again after editing, convert it to a compressed format with our WAV to MP3 converter or the audio compressor.

What input formats can I convert to WAV here?

The converter accepts AAC, AC3, AIF, AIFC, AIFF, AMR, AU, DSS, FLAC, M4A, M4B, MP3, OGA, OGG, Opus, VOC, WebA, WMA, and WAV itself — 19 formats in all. Whatever audio you have, it decodes to standard PCM WAV. If you want a lossless file that's smaller than WAV, our audio to FLAC converter keeps full quality at roughly half the size.

Will the WAV play on my device and in my software?

Almost certainly. WAV was created by Microsoft and IBM in 1991 and is natively supported on Windows, macOS, iOS, Android, and in Chrome, Firefox, Edge, and Safari, plus virtually every audio editor and DAW. PCM 16-bit is the most universally compatible profile; some very old or embedded players may not read 24-bit or 32-bit PCM, so keep 16-bit if maximum compatibility matters.

Is there a size limit on the WAV I can create?

The WAV format itself caps a single file at just under 4 GB, because the RIFF header stores the file size in a 32-bit field. That's hours of CD-quality stereo, so it rarely matters in practice. The more realistic limit for you is upload size and time — a very long uncompressed file is large to send, so trimming with the built-in Trim option before converting can help.
