Frequently asked questions

Can I merge MP3 files for free?
Yes. Add as many MP3 files as you like, arrange them in order, and merge them into one MP3 or WAV at no cost. There is no track limit beyond what your device can hold in memory, and no watermark on the result.
Can I reorder the tracks before merging?
Yes. Each track has up and down controls, so you can arrange them in any sequence before you merge. Preview the merged result before downloading to make sure the order is right.
Do the files need to be the same format?
No. You can mix MP3, WAV, OGG and M4A files in one merge. They are decoded and joined into a single continuous track, which you then export as MP3 or WAV. For the cleanest join, files that share a sample rate work best.
Is it really free, and is there a watermark?
It is free and there is no watermark, no sign-up and no email wall. You get the full-quality file straight back, with nothing added and nothing held behind a paywall.
Is my file uploaded to a server?
No. Everything runs locally in your browser. Your file is read and processed on your own device, nothing is uploaded, and nothing is logged or stored.
