Frequently Asked Questions
How do I merge two MP3 files into one?
Upload both MP3 files, drag them into the order you want, pick an output bitrate, and click Join. Our free audio joiner stitches them into a single MP3 you can preview and download in seconds.
Can I join more than two MP3 files?
Yes — you can upload as many MP3 files as you like and reorder them before joining. It's perfect for combining multiple songs, podcast segments, or voice notes into one track.
Is the audio joiner free?
Yes. Combining MP3 files online is completely free with no signup, no watermark, and no software to install.
Does joining MP3s re-encode the audio?
The output is re-encoded at the bitrate you pick (128k, 192k, 256k or 320k) so the result is a single clean MP3.
Which bitrate should I pick?
192k is a solid all-round default. Pick 320k for the best quality or 128k for the smallest file.
Can I preview before downloading?
Yes. After joining, an audio player lets you listen to the combined MP3 before saving it.
