Guide & best practices

Bitrate drives size: MP4 to MP3 at 192 kb/s is a common voice/music compromise.

Source stays MP4; output is MP3. Processing category: audio. You can queue multiple files when limits allow (see uploader hints).

PulsConv follows a zero-storage policy: files aren’t used to train models, aren’t indexed, and are deleted after delivery. Upload over HTTPS and keep your own backups if the output is business-critical.
