Choose Your Quality
Select output bitrate from 64kbps (voice quality) to 320kbps (maximum quality). For music, 192kbps or 320kbps is recommended. For podcasts and speech, 128kbps is sufficient and produces much smaller files.
Batch Audio Conversion
Convert multiple audio files at once. Upload up to 10 files simultaneously and download all converted audio files as a ZIP archive. Ideal for converting entire music libraries or podcast archives.
