Add Audio to Video Online for Free 

How to add audio to video online

An audio to video editor in the browser can add music to video clips, voice tracks, and other audio layers without desktop software. MP4 and other common video formats are supported. Audio can be placed over video and adjusted before export.

Follow these three simple steps:

Step 1. Upload your video and audio

Click Add file and select the video file. Then add an MP3 track or another audio file. Both files appear in the workspace and are ready for editing.

Step 2. Sync your sound

Place the audio over video and line it up with the needed part of the clip. Change the volume and trim audio fragmets if the track is longer than the video.

Step 3. Save your creation

Sounds just right? Export the video without watermark. The finished file can be downloaded for free.
