About This Tool

What Is an Audio Merger?

An audio merger is a tool that combines two or more audio files into a single continuous track. Our free browser-based merger works with MP3, WAV, OGG, M4A, and FLAC files — no software to install, no file size limits, and no privacy concerns since everything runs locally.

Perfect for creators joining podcast segments, musicians assembling multi-part compositions, video editors prepping soundtracks, or anyone needing to stitch audio clips together quickly.

How to Merge Audio Files

Simply drop your audio files onto the zone above, drag them into the order you want, optionally set a silence gap between each track, then hit Merge. Your browser combines them in seconds and gives you a download link — no waiting, no queues, no limits.
