Bulk Conversion Steps

1

Import your bulk listing

Select multiple audio songs at once using Ctrl or Cmd keys, or drag the entire directory into the box.

2

Choose Common Audio Quality

All selected files will be converted into your chosen quality profile (such as 320kbps MP3s).

3

Queue and Download

Our system processes each audio track in sequence. Download them with a single click once done.

Optimizing Bulk Conversions

To make compiling large playlist files optimal, we suggest shutting down redundant memory-heavy browser windows or background gaming apps during processing. This leaves maximum memory addresses free for standard WebAssembly operations, enabling faster conversions.
