Merge MP3 files

Upload audio files, arrange them in the order you want, and merge them into a single MP3 file.

How merging MP3 files works

Drop in two or more MP3s, arrange them in the order you want, and the tool joins them into a single MP3 file. Everything runs locally in your browser, so even a 40-chapter audiobook merges without uploading a byte.

What people merge

Audiobook chapters into one file for players that lack playlist support. Podcast intro, interview, and outro segments into a finished episode. Lecture recordings split by a recorder into one continuous file. DJ sets and mixtapes assembled from individual tracks.
