How to turn audio into a video
Open an MP3, M4A, WAV, or FLAC, add a picture or pick a background color, and save an MP4 that plays the sound over it. Choose the picture's own shape, landscape for YouTube, square, or portrait for Reels and TikTok. The audio to video converter runs in your browser, so nothing is uploaded.

What to expect
- Supported inputs
- Audio files such as MP3, M4A, WAV, FLAC, and OGG, or a video whose sound you want. Pictures can be PNG, JPEG, or WebP.
- What happens
- The video lasts as long as the sound, with the picture held still throughout. AAC audio, as in M4A files, is copied without re-encoding; other audio is encoded as AAC, or MP3 where the browser has no AAC encoder.
- Limits
- One sound and one picture per video. The picture doesn't move; use Add audio to video to put a sound under moving footage.
