How to Reduce Your Audio File Size in 3 Simple Steps

Step 1: Upload Your Audio File

To get started, drop your music or audio file into the upload area, or click "Select File" and browse your device. The audio compressor can handle:

• MP3, WAV, and all other popular formats - whether you are looking to compress a MP3 file, or upload a WAV file, we can handle it.
• Files up to 100MB in size (basically you won't have to worry about exceeding this limit in any normal circumstance - always perfect for compressed full albums or high-quality recordings).
• Batch upload - compress multiple audio files to save time.
• No signup - just press upload to start compressing.

A tip for you: Although our sound compressor does an amazing job maintaining the audio quality you are likely to notice, it's never a bad idea to hold onto your original file.
