How to use Compress Audio
- 1
Choose an MP3, WAV, M4A/AAC, FLAC, OGG or Opus file and inspect the source codec, bitrate, duration and size.
- 2
Select Light, Balanced, Strong, Maximum or Custom compression. The interface shows the exact target bitrate behind the preset.
- 3
Choose MP3, M4A/AAC, OGG, Opus or Same as source when that lossy source is compatible, then review the estimated size and any efficiency warning.
- 4
Click Compress Audio and use Original and Compressed to compare the source with the real encoded output. Review the actual bytes saved before downloading.
Frequently asked questions
About Compress Audio
Large audio files are inconvenient for messaging, web publishing and limited storage, but simply choosing a low number without context can damage intelligibility or music detail. Compress Audio connects each named preset to a visible codec bitrate and also offers Custom values, allowing the size-versus-quality decision to be made deliberately.
Before encoding begins, the estimate combines track duration, target bitrate and a small allowance for the container. It is guidance rather than a promise: a file that is already compact may have little room to shrink, and the workspace says so. After compression, the displayed comparison uses the actual result size, not the earlier estimate.
The A/B player is equally important. Original plays the uploaded source, while Compressed plays the exact file prepared for download, so artifacts can be judged before saving. The job runs only after Compress Audio is selected and stays on the device throughout inspection, encoding and preview.
