How to use this tool

  1. Drop or select an audio file (MP3, WAV, AAC, OGG, FLAC, or M4A).

  2. Choose a quick preset (High Quality, Balanced, or Extreme Compact) or pick a custom bitrate (from 64 kbps to 320 kbps).

  3. Optionally check Convert Stereo to Mono to drastically halve file size for speech, voice memos, and podcasts.

  4. Select your target compressed container format (MP3, M4A, or OGG).

  5. Click Compress Audio to encode the track locally via WebAssembly.

  6. Listen to the compressed playback in the preview player and download your lightweight audio file.

Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

The compressor re-encodes the audio track using advanced psychoacoustic codecs (like MP3 LAME or AAC) at an optimal target bitrate. It removes inaudible acoustic frequencies, dramatically shrinking the number of bytes required per second.
For rich music soundtracks, 192 kbps or 128 kbps delivers a great balance of clarity and file size reduction. For podcasts, voice notes, audiobooks, and interviews, 64 kbps or 96 kbps provides massive space savings while keeping speech fully legible.
Stereo audio records two separate channels (left and right). For voice recordings, lectures, and speech where directional audio is not required, downmixing to mono cuts channel data by 50% immediately.
Yes! You can compress large uncompressed WAV or FLAC masters (often 50–100MB) down to a compact 3–5MB MP3 or M4A file in seconds.
Zero. Everything runs 100% locally on your computer inside your browser's WebAssembly sandbox. Your audio tracks are never transmitted over the internet.
