MP3 album art: embedded covers and why they do not show
An MP3 can carry its cover image inside an ID3 attached-picture (APIC) tag. That embedded cover travels with the file; a separate cover.jpg does not. Adding artwork changes metadata, not the audio quality.

Key facts
A JPEG marked as front cover is a practical compatibility starting point. Support for PNG, dimensions and ID3 versions varies by player.
A folder image and an embedded image are different. Some players read cover.jpg; others only read the picture stored inside each MP3.
The picture is copied into each tagged file. A 300 KB cover added to 100 tracks adds roughly 30 MB in total.
Embedded artwork can be present even when a player shows an old image. Music-library caches and device-specific limits can affect display.
Practical decisions
- Use the Add Cover Art tool below: choose your MP3, choose an image you own or may use, process it and download the new copy. The local tool does not upload your media.
- Test the newly downloaded file, not the original MP3. Renaming a file or placing a picture beside it does not embed the cover.
- For an older MP3 player, try one modest square JPEG, for example 500 by 500 pixels, then check its manual. No image size works on every device.
- If the cover remains missing, reopen the downloaded copy in another player and refresh the original player's library. Check the cover-art troubleshooting guide for the next steps.
Measure the source before changing it. Codec, container, duration, channels, and intended playback environment are more useful than choosing a setting from its label alone.
