Merge MP3 Files

Merge several MP3s into a single MP3 file: songs for a mix, chapters of an audiobook, or parts of a recording. Put them in order, choose crossfades or gaps, and download. Your files stay on your device.

Works with MP3, M4A, WAV, OGG, FLAC and the sound from videos. Which formats open depends on your browser.

    How to use the Merge MP3 Files

    1. Drop your MP3 files into the box, or click choose files.
    2. Use ↑ ↓ to put them in order.
    3. Pick what goes between them, then click Join clips and Download.

    Why not just stick the files together?

    Some tools merge MP3s by gluing the files end to end. That's quick, but it can leave tiny clicks at the joins, wrong track lengths in some players, and leftover tags from the first file. Here each MP3 is decoded and the audio is joined before encoding one clean MP3, so the joins are seamless and the length is correct.

    Audiobooks and podcasts

    For spoken audio, 128 kbps is plenty and keeps the file small: about 1 MB per minute. Choose Nothing between clips to keep the speech continuous, or a short pause between chapters.

    Frequently asked questions

    Will the merged MP3 keep the song titles?

    No. The result is one new MP3 without the original tags.

    Can I merge other formats into an MP3?

    Yes. M4A, WAV, OGG, FLAC and the sound from videos can all be added, and the result is saved as MP3.
