Upload multiple files, set a target bitrate (e.g. 128 kbps), and all files are compressed to MP3 with that bitrate sequentially.
128 kbps is a good balance for most uses. 96 kbps for voice content. 192-256 kbps for music that needs better quality.
Yes. Batch compression outputs all files as MP3 for maximum compatibility and smallest file size.
