Audio Merger/Joiner
Combine multiple audio files into one, preserving order. Processing happens entirely in this tab — no upload.
Drop audio files here, or click to choose (multiple allowed)
How this works
This tool uses ffmpeg.wasm to run FFmpeg in the browser. It concatenates the input audio files (must be same codec/sample rate or will be re-encoded) and outputs a single file in the format of the first input (or you can specify output format). All processing happens locally — no upload to a server.
Common uses
Combining podcast episodes, joining music tracks, creating audiobooks from chapters, or assembling voice recordings.
