What is a WAV compressor?

A WAV compressor reduces the amount of PCM data stored in a WAV file by lowering its sample rate, bit depth, channel count, or a combination of those settings.

WAV is normally uncompressed, so choosing WAV output does not use an MP3-style bitrate slider. The estimated size comes directly from duration, samples per second, bytes per sample, and the number of channels.

Choose the WAV sample rate

Use 22.05, 32, 44.1, or 48 kHz according to the frequency range and delivery requirement.

Set 16, 24, or 32-bit PCM

Lower bit depth reduces data per sample; higher bit depth preserves more level resolution for production workflows.

Switch stereo to mono

Use one channel for speech or mono sources to reduce size substantially without storing duplicate stereo information.

How to compress a WAV file online

Keep an untouched master when the original WAV may be needed for future editing, mixing, or mastering.

  1. 1

    Upload one or more WAV files

    Add a single WAV or switch to Batch Compress to process up to 10 files with the same settings.

  2. 2

    Keep WAV as the output

    WAV is preselected on this page so the controls focus on PCM sample rate, bit depth, and channels.

  3. 3

    Choose smaller PCM settings

    Lower the sample rate or bit depth, and select Mono when the content does not require stereo.

  4. 4

    Check the estimate and export

    Review the expected size, process locally, compare the result, listen, and download the compressed WAV.

When smaller WAV output is useful

Use configurable WAV when a workflow requires PCM audio but the source settings contain more data than the destination needs.

Speech and transcription

Convert voice recordings to mono and a lower sample rate when the speech system does not require full stereo music bandwidth.

Dataset and application limits

Match a required WAV sample rate, bit depth, and channel layout before importing audio into another system.

Smaller editing proxies

Create lighter WAV copies for review or temporary editing while retaining the full-resolution master separately.

Legacy and embedded playback

Prepare PCM settings that match older hardware, telephony tools, games, or devices with strict audio requirements.

How WAV settings affect file size

For PCM WAV, file size scales directly with sample rate, bit depth, channel count, and duration.

WAV settingsPCM data rateTypical use
48 kHz / 24-bit / Stereo2,304 kbpsProduction, video, and high-resolution editing
44.1 kHz / 16-bit / Stereo1,411 kbpsMusic delivery, CD-quality PCM, and general editing
44.1 kHz / 16-bit / Mono706 kbpsMono music, voice, and compatible speech workflows
22.05 kHz / 16-bit / Mono353 kbpsCompact speech, previews, and limited-bandwidth applications

Lowering sample rate or bit depth discards information. Converting stereo to mono also changes the channel image, so keep the original WAV master.

Frequently Asked Questions

How can I reduce WAV file size and keep WAV output?

Lower the sample rate, bit depth, or channel count. The estimated output size updates before compression so you can compare settings.

PCM WAV stores every sample without perceptual compression. Size is determined by duration multiplied by sample rate, bit depth, and channel count.

Lowering sample rate or bit depth removes information, and changing stereo to mono changes the channel image. Keep the original when it is a master or production source.

Use 44.1 kHz for common music workflows, 48 kHz for video and production, 32 kHz for reduced-bandwidth audio, or 22.05 kHz for compact speech and previews.

Use 16-bit for smaller delivery files and broad compatibility. Use 24-bit when additional level resolution matters during editing or production.

Yes. Add up to 10 files, apply one set of PCM output settings, and download the completed WAV files individually or together as a ZIP.

Yes. Return to the full Audio Compressor and choose MP3, M4A, or OGG when the destination does not require WAV. Lossy output will normally be substantially smaller.
