Audio Merger – Free Online MP3 & WAV Joiner, No Upload Needed

Audio Merger (https://audiomerger.org/) is a free browser-based tool for joining multiple audio files into one track. Add your MP3, WAV or M4A files, arrange them in any order, trim each clip, and fine-tune every joint with a silence gap or a smooth crossfade. You can preview each joint separately before exporting a single MP3 or WAV file. Everything runs locally in your browser using FFmpeg WebAssembly – your files are never uploaded to any server. No account, no signup, completely free. Useful for podcasters, musicians, language learners and students who need a quick, private way to merge audio clips.
