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, CAF, OGA, WebA, VOC, and DSS 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 Audio Channel and Sample Rate (Optional): Both default to "Original" so the source is copied exactly; force Mono / Stereo, or a fixed rate such as 44100 Hz or 48000 Hz, only when a target device needs it.
4. Convert and Download: Click "Convert" and save your WAV. No sign-up, no watermark.

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 identical to 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 whether it's music or silence. In our testing, a 3-minute 192 kbps MP3 of roughly 4 MB became a ~30 MB WAV — about seven times larger. If you need the file small again after editing, convert it back with our WAV to MP3 converter or shrink it in the audio compressor.

Should I change the sample rate, or leave it on Original?

Leave Audio Sample Rate on "Original" in almost every case — it copies the source rate exactly and avoids needless resampling. Only set a fixed rate when a target system demands one: 44100 Hz for CD authoring, 48000 Hz for video and most DAWs. Raising the rate above the source (upsampling) never adds detail that wasn't recorded; it just enlarges the file.

Does converting FLAC or ALAC to WAV lose any quality?

No. FLAC and ALAC are lossless, so decoding them to PCM WAV reproduces the original samples bit-for-bit — the WAV is simply the same audio stored without compression, which is why it lands at roughly twice the size. This is the one case where "convert to WAV" gives you a truly full-quality file, because nothing was thrown away to begin with. For a lossless file that stays smaller than WAV, our audio to FLAC converter keeps full quality at about half the size.

What input formats can I convert to WAV here?

The converter accepts AAC, AC3, AIF, AIFC, AIFF, AMR, AU, CAF, DSS, FLAC, M4A, M4B, MP3, OGA, OGG, Opus, VOC, WebA, WMA, and WAV itself — 20 formats in all. Each one decodes to standard PCM WAV, whether the source was lossy or lossless.

What is the difference between WAV and AIFF?

Both are uncompressed PCM containers, so they sound identical at the same bit depth and sample rate. The practical difference is byte order and heritage: WAV stores little-endian samples in a RIFF container (the Microsoft/IBM Windows default), while AIFF stores big-endian samples in an Apple-designed container. Windows software and most DAWs read both, but WAV is the safer pick for cross-platform sharing. Use the audio to AIFF converter instead if your workflow is built around Apple's format.

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

Almost certainly. WAV is natively supported on Windows, macOS, iOS, and Android, in Chrome, Firefox, Edge, and Safari, and in virtually every audio editor and DAW. PCM 16-bit Little Endian 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 file I can create?

The WAV format itself caps a single file at just under 4 GB, because the RIFF header stores the total size in a 32-bit field. That is several hours of CD-quality stereo, so it rarely bites in practice, and the RF64 extension exists for longer recordings. 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.
