Merge MP3 files
Merge several MP3s into one MP3, in the order you choose.
Your files stay on your device. Nothing is uploaded.
How to join audio files
- Choose two or more files: MP3, M4A, WAV, FLAC, OGG, or videos whose sound you want.
- Put them in order with the arrows, and pick a crossfade if the songs should blend into each other.
- Press "Join audio" and download the file.
Crossfade or straight cut
Without a crossfade the files play one right after the other: good for chapters of an audiobook or parts of a recording. A crossfade lowers the end of one file while the next one starts, like a DJ mix; the joined file is that much shorter for each join.
Your files stay on your device
Nothing is uploaded. The files are joined in your browser, so recordings stay private.
FAQ
Frequently asked questions
Short answers about how this tool works on your device.
Does merging MP3s lower the quality?
The joined file is encoded again at 192 kbps, which sounds the same as the originals to almost everyone.
Can I join files of different formats?
Yes. An MP3, a WAV and a voice memo can go in one list; they are brought to the same sound settings and saved in the format you pick.
Are my files uploaded?
No. Everything runs in your browser, so your files stay on your device. Nothing is uploaded.
Is Snipmill free?
Yes. Snipmill is free to use and needs no account. You can join up to 10 files at once.
