Key Features
Browser-Based Processing
Replace the audio track in a video locally in your browser, so your source files stay on your device.
Multi-Format Support
Use MP4, MOV, MKV, and WebM videos with MP3 or WAV audio. MP4, MOV, and WebM are the most reliable across browsers.
High-Quality Output
The video stays as it was - only the soundtrack is swapped for your new audio.
Privacy First
Your media is processed locally. It is not uploaded to DojoClip for this tool.
Easy to Use
Add your video, add the new audio, and download - one video, one track, done.
Fast Processing
Most swaps finish in seconds to a couple of minutes, depending on file size and your device.
Supported Formats
Works with common browser-friendly formats:
MP4MOVMKVWEBMMP3WAV
Best for
Use the audio replacer when a video needs cleaner music, a revised voiceover, or a new soundtrack without opening a full editor. It is designed for straightforward one-video, one-audio replacement.
Practical notes
Choose an audio file that is close to the video length when possible. If the new track is much shorter or longer, trim it first so the final clip ends cleanly.
Getting your audio ready
Need to pull a track from another video first? Use the audio extractor. To strip the current sound before adding a new one, try the audio remover. For a fuller mix with music and captions, build it in the AI Video Editor.
FAQ
Is Audio Replacer free?
Yes. Audio Replacer is available as a free browser tool for quick media work.
Are my files uploaded?
No. This workflow is designed to run locally in your browser, so your source file stays on your device.
Which formats are supported?
Use common video files like MP4, MOV, MKV, and WebM with an MP3 or WAV audio track. MP4, MOV, and WebM are the safest inputs across browsers.
When should I use a browser tool instead of desktop software?
Use it for focused edits when speed and privacy matter. A full editor is still better for complex timelines, color work, or large batch production.
