What to expect
- Supported inputs
- M4A files, and any other audio or video with sound this browser can read. Pictures can be PNG, JPEG, or WebP.
- What happens
- The sound plays over a still picture for its full length. AAC audio is copied without re-encoding; other audio is encoded as AAC, or MP3 where the browser has no AAC encoder.
- Limits
- One sound file at a time. The picture stays the same for the whole video; use Add audio to video to put a song under moving footage.
Your files stay on your device
Your computer does the work, so the file never has to be uploaded, and that’s also why it’s free: there’s no server time for us to pay for. You don’t need an account, and nothing you make gets a watermark.
