MP3 (see the Audio Joiner for WAV, OGG and FLAC).
A playlist still plays as separate files — gaps, shuffled order, and no way to share it as one thing. Merging produces a single MP3 file you can send, upload, or burn anywhere. That's why merged files win for mixtapes, meditation sequences, event soundtracks and continuous DJ-style sets.
Need WAV or FLAC output, or want to mix formats? Use the full audio joiner. Prefer musical blends between songs? The MP3 joiner preset applies crossfades by default.
Upload your MP3 files above, arrange them in order, and click Merge MP3s. The combined file downloads immediately — free, no account, no watermark.
Quality stays effectively identical. Files are decoded once, joined, and encoded once at a matching bitrate — there are no repeated lossy re-encode cycles.
Yes. Files with different bitrates or sample rates are automatically aligned before joining, so the output plays smoothly from start to finish.
No hard limit — merge two files or twenty. Very large sessions simply take a few more seconds to process.
No. The merger runs entirely in your browser using WebAssembly. Your music never leaves your device.
This page is preset for MP3. For WAV, OGG and FLAC — or for mixing formats in one merge — use the full free audio joiner, which supports all of them.
