Frequently Asked Questions

Q: Does compressing audio reduce sound quality?

A: We use advanced perceptual audio encoding (VBR/CBR) to remove frequencies inaudible to human ears, keeping your podcasts, music, and voice notes crisp while shrinking file size.

Q: Are my audio files uploaded to any server?

A: Never. All audio compression is executed directly in your browser using local WebAssembly (FFmpeg WASM). Your voice recordings and tracks remain 100% private.

Q: Which audio formats are supported for compression?

A: You can compress MP3, WAV, AAC, M4A, FLAC, and OGG files easily without installing any software or plugins.
