Merge multiple files in your chosen order, set crossfades and download the result.
Up to 20 files, 60 minutes in total.
The file is decoded and measured inside your browser.
Drop two or more files to join them.
The crossfade is applied at the joint before each file. 0 ms is a hard cut; joints are ramped exactly like the cuts in Audio Cutter, so they do not click.
This free online audio joiner merges multiple songs into a single file: you set the merge order, the crossfade length at each join and the output format, then download the result.
Every join is measured and shown before you render, and the whole merge runs locally on your machine — no upload limit, no queue, no watermark.
Drop the audio files you want to merge. They are decoded locally.
Arrange the join order and set the crossfade length between neighbouring files.
Confirm the output format and download the merged file.
