Frequently asked questions
Is the audio joiner free?
Yes. Merging costs nothing, the download has no watermark and there is no signup.
How many files can I merge?
Up to 10 files in one go, each up to 100 MB. They are joined in the order you add them.
Can I mix different formats?
Yes. You can join MP3, WAV, FLAC, M4A and OGG files together — they are decoded, merged and re-encoded to the single output format you choose.
What is a crossfade?
A crossfade smoothly blends the end of one clip into the start of the next so there is no hard cut between them. Set it to zero for a straight join.
Can I change the order of the clips?
Yes — the clips are merged in the order they appear in the list, so arrange them before you process.
Do my files stay private?
Your files are processed on our own servers and deleted automatically, and nobody else sees them. The download link is unguessable and is never listed or shared anywhere.

Perfect even with opera, jazz, etc. It's like a dream...🥹
Perfect même avec de l'opéra , Jazz etc... Comme un rêve ...🥹
It's a bit annoying that I have to select the conversion type every time, and my initial selection doesn't stick. Other than that, everything's fine.
קצת מעצבן שכל פעם צריך לבחור סוג המרה ולא נשאר מה שבחרתי ראשון חוץ מזה הכל טוב
If you want to analyze everything from the individual instruments to the vocal arrangements in a song, VocalRemover is exactly what you need. You can listen to every component of your song in detail. I don’t usually leave comments, but I decided to leave one here because I imagine that if someone has made it this far and has doubts or needs encouragement to use VocalRemover, they should go ahead and do it—they won’t regret it!!
Si buscás estudiar desde cada uno de los instrumentos hasta cada arreglo vocal de una canción, vocalremover es lo que buscás. Podés escuchar cada componente de tu canción al detalle. No suelo dejar comentarios, pero decidí dejar uno acá porque imagino que si alguien llegó hasta acá y tiene dudas y necesita ánimo para usar vocalremover que lo haga tranquilo, no se va a arrepentir !!
Really great—the best of the best
