Questions
Can I mix MP3, WAV and M4A?
Yes. Each file is decoded by your browser and joined at the same quality, then saved in the format you pick.
What does “Smooth joins” do?
It adds a tiny 30 millisecond fade at each join so you do not hear a click where two files meet.
Is there a limit?
Up to a few hours of audio in total, depending on your device’s memory.
Is my data private?
Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.
Is it free?
Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
