Add Audio to Video

What is Add Audio to Video?

Add Audio to Video lets you merge a separate audio file with a video. Replace the original audio track entirely or mix a new track on top — ideal for adding music, voiceovers, or sound effects to silent footage or replacing low-quality recorded audio.

How to use

1. Upload your video file (MP4, WebM, MOV) and the audio file (MP3, WAV, OGG) you want to add.
2. Choose whether to replace the existing audio or mix the new audio with the original. Set volume levels and audio offset timing.
3. Process the video and download the result with the new audio track embedded.

Result

A content creator uploads a drone footage MP4 with wind noise and an MP3 background music track, sets 'replace audio' mode, and downloads the final video with clean music instead of wind noise.
