How to add custom art to non-Steam games on Steam Deck

Adding custom Steam games means missing out on artwork, which can make your library look disjointed, but luckily, we show you how to add custom art to non-Steam games on Steam Deck to your entire library look fresh. 

The Steam Deck has made a name for itself for being a multifunctional handheld. Unlike the Nintendo Switch, you aren’t limited to playing Steam games on the device. With some clever tinkering, you can add a ton of non-Steam games, and apps, onto the Steam Deck. Yet, unlike native Steam games, they won’t come with artwork.

Instead, non-Steam games have a gray box, with the app’s title in plain white text by default. To make non-Steam games look more unified with the rest of your library, you can add custom art. We have all you need to know about adding custom art to non-Steam Deck games, to ensure your library looks its best.
