Common questions
Are my files uploaded anywhere?
No. The music is mixed in inside your browser. Your video and song are never sent to a server.
Can I keep the original sound too?
Yes. Use the Original sound slider: 0% replaces it with the music, higher values mix both. The mix is turned down automatically if it would distort.
What if the song is shorter or longer than the video?
A shorter song repeats (you can turn that off), a longer one is cut to the video's length, with a gentle fade-out at the end.
Is Add Music to Video free?
Yes, completely free, with no sign-up and no watermark. It works for videos up to 15 minutes. Only use music you have the rights to.
