Audio Compressor
Compress audio dynamics online — even out loud and quiet parts of any recording in your browser. Output is WAV, free, no upload. — free, fast and private.
How to use Audio Compressor
- Choose an audio file (MP3, WAV or any format your browser can play).
- Pick a compression ratio and threshold — higher ratios even out the volume more.
- Click Compress Audio.
- Download the compressed WAV file.
Honest limit: Output is WAV (16-bit PCM) — browsers cannot encode MP3. The tool applies a real dynamics compressor (the same kind used in studios) and then normalises the peak so the result is evenly loud without clipping.
Frequently Asked Questions
Is the audio compressor free?
Yes, it is 100% free with no sign-up. Your audio never leaves your browser.
What format is the output?
WAV (16-bit PCM). Browsers cannot encode MP3, so WAV is the honest output — it plays everywhere and keeps full quality.
What does compression actually do?
It turns down the loudest moments so quiet parts can be heard more clearly, then brings the whole level back up. Great for podcasts, voice notes and uneven recordings.
Will it remove background noise?
No — compression only evens out volume. For noise, use our Noise Remover tool.
