Frequently asked questions

What is the difference between muting and replacing audio?

Muting removes the original audio entirely, leaving a silent video you can add sound to later. Replacing swaps the original audio for a new MP3 track, which is best for YouTube or Facebook.

Will muting or replacing audio reduce my video quality?

No. The video stream is kept lossless — only the audio track is changed — so the picture stays exactly as it was.

How do I avoid copyright (DMCA) problems?

Use CC0 music or music you own the rights to. Free CC0 tracks, such as those from Pixabay, are safe, while songs from Spotify or YouTube Music are not allowed.

What formats and file size are supported?

You can upload an MP4 video up to 500 MB, and for the Replace option you add a new MP3 audio file.

Is it free and is my file kept private?

Yes, it is free with no watermark and no signup. Uploaded files are processed and then automatically deleted after 10 minutes.
