How to use Add Cover Art to MP3

  1. 1

    Choose an MP3 already on your device. Keep the original as a backup.

  2. 2

    Under Cover image, select a JPEG or PNG you own or have permission to use. A modest square image is a useful starting point; check your player's requirements.

  3. 3

    Select Add Cover Art to MP3 and keep the tab open while the image is embedded.

  4. 4

    Download the new MP3, open that copy in your player, and refresh its library if the old artwork still appears.

What this tool changes

The tool copies the MP3 audio stream and embeds your JPEG or PNG as the front cover without re-encoding either. Choose JPEG if your player requires it. It does not search for artwork, restore audio quality, or change the original file.

Example: choose your own recording.mp3 and cover.jpg, run the tool, then download the resulting MP3. The picture travels inside the downloaded file, but display still depends on the player.
