Frequently Asked Questions
Common questions about reversing audio files online.
What audio formats can I reverse?
You can reverse MP3, WAV, OGG, AAC, FLAC, and most other common audio formats. The output is saved in the same format as the original file.
Is my audio uploaded to a server?
Never. FFmpeg runs as WebAssembly in your browser. Your audio file never leaves your device — no upload, no server processing, completely private.
Will reversing change the audio quality?
The audio is decoded, reversed, and re-encoded. For lossy formats like MP3, there is a minimal re-encoding step. Use WAV for lossless reversal.
Can I reverse just a portion of an audio file?
Currently the tool reverses the entire audio file. To reverse a specific section, use the Audio Trimmer to cut the segment first, then reverse it here.
