Action

Browser-side processing exports PCM WAV. The size-reduction option converts to mono 22.05 kHz PCM, which can reduce WAV size but is not MP3 encoding. Large files may exceed browser memory.

HOW IT WORKS

Simple, transparent tools

Paste or upload

Check a link's format, extract audio from a video file you provide, or choose local audio files.

Process locally

Extraction and audio editing run in your browser. Your local files are not uploaded to this server.

Download real output

Download appears only after processing succeeds. Output type depends on the selected tool and browser support.

GUIDE

How to use the Audio Compressor

Reduce the size of a WAV file by converting it to mono audio at 22.05 kHz. This trades some quality for a smaller file, and it only makes WAV files smaller — it does not compress MP3 files.

Steps

Choose an audio file you own or are authorised to use (30 MB maximum).
Make sure Reduce WAV size is selected, then select Process audio.
Read the result message, which states the mono 22.05 kHz output plainly.
Preview the result, then download the WAV file and compare its size with your original.

Supported inputs and outputs

Inputs: audio files your browser can decode (MP3, WAV, M4A, and similar).
Output: PCM WAV, one channel (mono), 22.05 kHz sample rate.
The size saving comes from halving the sample rate and dropping to one channel, compared with a full-rate stereo WAV.

Troubleshooting

If the output is larger than your original MP3, that is expected: WAV is uncompressed, while MP3 is compressed. This tool shrinks WAV files, not MP3 files.
If the output sounds duller, that is the mono 22.05 kHz reduction working as designed. It suits voice and simple audio better than music.
A file that will not decode needs a browser-supported format.

Frequently asked questions

Will this make my MP3 file smaller?

No. The output is WAV, which is usually larger than the MP3 you started from. Use this tool to shrink WAV files.

How much smaller will the WAV be?

Compared with a stereo 44.1 kHz WAV of the same audio, roughly a quarter of the size, because the rate is halved and the channels drop from two to one.

Does it affect quality?

Yes, by design. Mono 22.05 kHz keeps speech clear but loses stereo detail and high frequencies.
