What is the Online Audio Merger?
The Online Audio Merger lets you combine two or more audio files into a single, continuous track. Upload all your clips, arrange them in the order you want, and the tool stitches them together end-to-end and gives you one file to download.
It runs entirely in your browser using FFmpeg.wasm, so your files are never uploaded to a server. There’s no account, no watermark, and no artificial file size limit tied to a subscription.
How to Merge Audio
- Add files — upload two or more audio files you want to join.
- Reorder — drag files up or down in the list to set the playback sequence.
- Merge — click “Merge Audio Files” and wait a moment for processing.
- Download — save the combined audio file to your device.
Use Cases
Podcast production — stitch together an intro jingle, a recorded interview, and an outro into one clean, ready-to-publish episode.
Voice memos — combine several short recordings made on a phone into a single file that’s easier to manage and share.
Music projects — join backing tracks, verse recordings, and chorus takes to hear a rough arrangement of a song without needing a full DAW.
Audiobook assembly — combine individually recorded chapters into a single long-form audio file for distribution.
Playlist creation — merge multiple songs or clips into one continuous track for a DJ set, workout mix, or presentation background.
Why Use This Tool
Most audio joiners either require desktop software or upload files to a remote server for processing. This tool does neither. Everything happens in your browser tab, which means your audio is private by default and there’s no waiting for files to upload and download from a server.
