WAV Peak Normalizer
Adjust integer PCM WAV audio to a target peak level and export 16-bit PCM while preserving channels and sample rate.

- Review the format options, then select Convert on server to process the input.
- Check the result and download the output file.
What this tool does
Make a quieter WAV use more of the available sample range or reduce its maximum peak to a chosen level. The converter measures the largest absolute sample, computes one gain value and applies it consistently to every channel. A target below zero dBFS leaves peak headroom. The output uses 16-bit integer PCM at the source sample rate.
Supported formats and limits
Peak normalization is not perceived-loudness normalization, compression, limiting or noise removal. Stereo balance and relative dynamics are kept, while silent input remains silent. Source audio must be mono or stereo RIFF/WAVE integer PCM at 8, 16, 24 or 32 bits. Float, compressed and extensible WAV are unsupported. Quantization to 16 bits can change sample values. Files and output must stay within 4 MiB; listen before replacing an original.
What should I check before using the result?
Peak normalization is not perceived-loudness normalization, compression, limiting or noise removal.
Is input uploaded?
This tool sends input to this site’s conversion API after you select Convert on server. Files use bounded workers and, when needed, private temporary folders deleted after processing or cancellation. No conversion history is saved. The converter does not upload files to a third-party conversion service.
