The audio merger tool combines several files into one, respecting the order you choose — perfect for joining several voice notes, merging audiobook chapters, stitching together recording segments, or creating a single file from several songs. You can mix different formats with each other (for example an MP3 with a WAV) without any issue, because each file is decoded separately before being merged. The result downloads as a single MP3. The whole process runs with FFmpeg compiled to WebAssembly, inside your own browser.
