Frequently Asked Questions
How does audio compression reduce file size?
The tool re-encodes audio as MP3 or OGG at the bitrate you choose. A lower bitrate usually creates a smaller file and can reduce sound quality.
Will the compressed file always be smaller?
Not always. The result depends on the source format, bitrate, and duration. The tool estimates the output before processing and compares actual file sizes afterward.
Which bitrates are available?
Choose 64, 96, 128, 160, or 192 kbps. The available output formats are MP3 and OGG.
Is my audio stored?
No. Your file is processed for this request, and the temporary processing files are deleted when it finishes.
