Free Online Audio Merger — Join MP3 & More

Have a handful of separate clips that should really be one file? Our free audio merger joins two or more tracks into a single, seamless recording. Just add your files, drag them into the order you want, pick an output format and download the finished piece. There is no software to install, no account to create and no watermark on the result.

Merging audio is one of those small jobs that comes up all the time. Podcasters use it to stitch an intro, the main interview and an outro into one episode. Audiobook listeners join separate chapters into a single file for easier listening in the car. DJs and music fans build one continuous mix out of several tracks. Teachers and students combine recorded notes, and anyone with a phone full of voice memos can merge them into one tidy file instead of scrolling through dozens of clips.

You do not have to worry about matching formats first. Drop an MP3, a WAV and an M4A together and the joiner re-encodes everything into one consistent output, so there are no jarring jumps in volume or format between sections. The order is fully in your hands — use the up and down arrows to arrange the clips exactly how they should play, and the tool plays them back to back with no awkward gaps.

Everything happens right inside your browser using WebAssembly, which means your audio is never uploaded to a server. Your recordings stay private on your own device, and the merge is fast because nothing has to travel to the cloud and back. It accepts MP3, WAV, FLAC, M4A and OGG files and works on both desktop and mobile, so you can pull a finished file together wherever you are.

Frequently asked questions

Can I merge files in different formats?▾
Yes. Mix MP3, WAV, FLAC, M4A and OGG freely — they are all re-encoded into a single, consistent output file with no gaps between them.
Will the files play back to back without gaps?▾
Yes. The clips are joined end to end in the order you set, so the result plays as one continuous track with no silent breaks between sections.
Can I change the order after adding files?▾
Absolutely. Use the up and down arrows next to each file to rearrange them as many times as you like before you merge.
How many files can I combine?▾
Up to 12 files at a time. On phones, fewer and smaller files work best, because everything is processed in your device's memory.
Are my files uploaded?▾
No. Merging runs entirely in your browser with WebAssembly, so nothing ever leaves your device.
What format is the merged file?▾
You choose the output format before merging, so you can save the combined track as an MP3 for easy sharing or another format that suits your needs.
