MP3 to video

Turn an MP3 into a video with a picture, a color, or a visualizer, for YouTube or social posts. Processing stays on your device.

Files stay on your device

Drop an MP3

Then add a picture or a color, and bars that move with the sound if you like. Nothing is uploaded.

MP3, M4A, WAV, FLAC, and other audio, or a video with sound.

How to convert MP3 to video online

Open an MP3, add a cover image or a background color, and save an MP4 video that plays the song. Add a visualizer if you want something that moves. The MP3 to video converter runs in your browser, so nothing is uploaded.

  1. Step 1

    Choose your MP3
    Pick a file or drop it into the converter above.

  2. Step 2

    Add a picture
    Add an image or a color, and a visualizer if you like.

  3. Step 3

    Download the video
    Save an MP4 that plays your song.

What to expect

Supported inputs
MP3 files, and any other audio or video with sound this browser can read. Pictures can be PNG, JPEG, or WebP.
What happens
The video lasts as long as the MP3. The sound is encoded as AAC (MP3 where the browser has no AAC encoder), which every player and site reads.
Limits
One MP3 at a time. Use Add audio to video to put a song under moving footage.

Questions

Add a cover image, keep the landscape shape, and save the MP4. Upload it to YouTube like any other video.

Yes. The video shows the background color you choose, with a visualizer if you add one.

Yes, as AAC at 192 kb/s. At that rate, the difference from the MP3 is very hard to hear.
