Add audio to video easily online
Have you ever wanted to easily add audio to your video online? This website helps you do exactly that! Just upload your video, upload your MP3 sound file, and merge them together for a new MP4 with the updated soundtrack. Kapwing supports many different file formats for both audio and video, including MP3, MP4, AVI, MOV, 3GP, and more.
You can use our straightforward editor to merge your audio with your video's soundtrack online. Perfect for creating a music video or adding voiceover, sound effects, or an accompanying score.
