Convert Audio to WAV Online
Decode a supported audio recording and export a standard PCM WAV. Choose output settings for a speech workflow, audio editor or application that requires WAV rather than a compressed input format.

Add a file, adjust settings, and export a standard WAV audio file.
WAV output only. Input format support depends on what your browser can decode. Renaming a file is not conversion.

How to use Convert Audio to WAV Online
- Select one mono or stereo audio file. The browser determines whether its codec can be decoded.
- Choose the decoded-source or a specific sample rate, channel layout and 8-bit or 16-bit PCM.
- Create the WAV, check its duration and format summary, preview it and download the new file.
When to use this editor
Prepare a compatible WAV for a desktop editor, speech workflow or application that requires PCM audio. Decoding depends on the browser and source codec; conversion cannot restore missing audio detail.
A file extension is not a codec guarantee
MP3, M4A, Ogg and other containers can use different audio encodings. Decoding support depends on the browser and operating system. The decoder produces floating-point samples at its context rate; the decoded-source rate option preserves that decoded rate, not a promise about original container metadata. WAV export uses unsigned 8-bit or signed little-endian 16-bit PCM.
Worked example
A supported MP3 can become 44,100 Hz, stereo, 16-bit PCM WAV.
WAV payload bytes = frames x channels x bytes per sample.
Renaming an MP3 to .wav does not perform this conversion.Match explicit WAV settings instead of renaming a file
| Control | Choose | Why |
|---|---|---|
| Sample rate | 48 kHz | Use the explicit rate when the destination requires it. |
| Channels | Stereo | Choose deliberately; converting a mono source does not recreate a recorded stereo scene. |
| PCM depth | 16-bit | Matches this example specification; it is not a recovery of lost source detail. |
- Select a compatible mono or stereo audio file. Wait for decoding and inspect the displayed decoded-source information.
- Enter the destination's actual settings. Keep decoded-source rate uses the browser-decoded buffer's rate; do not infer the original compressed file's rate solely from that option.
- Create the WAV and review the output details and sound. Changing the extension from MP3 to WAV would not perform decoding or PCM encoding.
- Download and check the file in the receiving application. Retain the original for its tags, artwork and original encoded audio, which this WAV conversion does not preserve.
This is a settings exercise, not a converted-file demonstration. Output remains WAV only. Use Reduce WAV File Size when PCM size reduction is the task, or Audio Editor Studio for its separate supported export options.
Formats and limits
Output is WAV only. This tool does not encode MP3, AAC, FLAC or Opus, retain source tags/artwork, or recover quality lost to a lossy input codec. Mono/stereo sources are supported; surround inputs are rejected with an explanation.
Up to 50 MiB per file, 20 merge tracks and 30 million channel samples for decoded input and rendered output. Compressed files expand during decoding; available device memory can impose a smaller practical limit. Cancellation terminates WAV encoding; an in-flight browser decode/render may finish internally before controls are released.
Audio processing uses built-in browser APIs and a local worker. These editors do not upload your audio or load external processing libraries. A WAV export creates a new file; your original is not modified.

Frequently asked questions
Can I convert MP3 to WAV?
Yes, when your browser can decode the selected MP3. The result contains decoded and re-encoded PCM audio, not the original compressed bytes.
Can I convert WAV to MP3?
No. The output encoder in this editor creates PCM WAV only.
Does converting to 16-bit WAV improve a lossy source?
It creates a compatible PCM representation. It cannot restore detail already discarded by the original encoder.
Prepare a PCM file for another editor
Open a supported audio source and choose the rate, channels and PCM depth required by the destination. Create the WAV and inspect its duration and sound.
Before choosing the output
This focused tool does not encode MP3, AAC, FLAC or Opus. Uncompressed WAV can be larger than its compressed source and cannot recover detail already lost.
