Steps
- Choose one audio file from this device.
- Select 22,050 Hz, 44,100 Hz or 48,000 Hz for the target workflow.
- Start the local conversion and wait for output validation.
- Download the resulting .wav file and verify it in the destination editor.

Audio to WAV Converter
Decode audio into uncompressed 16-bit PCM WAV at 22.05, 44.1 or 48 kHz.
Files stay in your browser
The first run loads an approximately 31 MB FFmpeg WebAssembly core from this site. It does not use a CDN or upload your files.
Files are limited to 200 MB total and 20 minutes; mobile devices use an 80 MB limit. Reverse, GIF and boomerang tools have lower duration caps.
At most 60 download files are generated.
Choose files, set the controls, then start.

Practical guide
Create editing-ready 16-bit PCM WAV locally
WAV is useful when an editor, recorder or delivery system needs predictable uncompressed PCM audio. This tool decodes the source and writes signed 16-bit little-endian PCM at the sample rate you choose.
Settings and output
- 22.05 kHz
- Lower-bandwidth voice, previews or workflows that explicitly request it.
- 44.1 kHz
- Common for music-oriented audio and CD-derived workflows.
- 48 kHz
- Common for video, broadcast and many production timelines.

Reproducible example
Example inputAudio file: sample-1.wav
Sample rate = 48,000 HzCreates a probed and validated .wav (audio/wav). Actual method: PCM WAV avoids lossy compression and is useful for editing, at the cost of a much larger file. Output boundary: The output uses signed 16-bit little-endian PCM.
- 1
Choose Audio file sample-1.wav and first confirm that each required audio stream exists.
- 2
Use Sample rate = 48,000 Hz. The actual FFmpeg rule is: PCM WAV avoids lossy compression and is useful for editing, at the cost of a much larger file.
- 3
A download appears only after duration, stream type and .wav container validation. Also check this boundary: The output uses signed 16-bit little-endian PCM.

PCM WAV avoids lossy compression and is useful for editing, at the cost of a much larger file.
How does this tool process my file?
PCM WAV avoids lossy compression and is useful for editing, at the cost of a much larger file. Processing uses single-thread FFmpeg.wasm. The page does not upload, store or inspect file content outside this device. Cancel, error and page close terminate the worker and revoke temporary object URLs.
What limits apply to the output?
The output uses signed 16-bit little-endian PCM. Files are limited to 200 MB total and 20 minutes; mobile devices use an 80 MB limit. Reverse, GIF and boomerang tools have lower duration caps.
