About Merge Audio

Combine several audio files into a single continuous MP3. Add your clips, drag them into the right order, and ffmpeg.wasm joins them end to end — ideal for stitching together podcast segments, voice memos, or song parts into one track.

Merging runs entirely in your browser with no upload and no signup, and it works offline. Your audio files never leave your device.
