Compress WAV online
WAV is an uncompressed audio format: a simple adjustment can’t meaningfully shrink it without changing its structure, unlike MP3.
Accepted source formats
How it works
Drop your WAV file: its size depends directly on its duration and sample rate.
The file is compressed losslessly where possible, with a smaller size reduction than an already-compressed format would allow.
Download the result, still in WAV format.
Common mistakes
- Using a source file of poor quality.

- Overwriting the original file without keeping a copy.
