One-Stop Shop: How to Add Non-Steam Games to Your Steam Library (2024)

There are many places to buy video games, but Steam is easily the most popular among them. Not only is it a one-stop shop for PC games, but you can also add games you bought elsewhere. Whether you purchased a game through EA, the Epic Games Store, GOG, or itch.io, you can add it to Steam as long as it's installed on your computer. Here's how to add non-Steam games to the Steam app and the Steam Deck handheld.

First, open Steam and click Games > Add a Non-Steam Game to My Library. You can also click Add a Game in the bottom-left corner and select Add a Non-Steam Game. A pop-up will appear with all the software installed in your programs folder. If your game isn’t listed (and it likely won’t be), hit Browse. Go to the folder where the game is installed, click the game’s executable, and hit Open.

Take note that the game's page in your library won’t have any information beyond the name of the game and a button to launch it. however, you can still take screenshots through Steam. You can also change the name of the game by right-clicking on the game in the sidebar, clicking on Properties, and entering a new name.

If you followed the steps above, the game should also appear in your Steam Deck library. However, if you want to install a non-Steam game directly on the handheld, you must follow a more complicated process. First, hit the Steam button and go to Power > Switch to Desktop on the Steam Deck to open desktop mode.

Make sure the game you want to put on Steam is downloaded onto the Steam Deck, either on internal storage or the SD card, if you have one. Once it’s downloaded, open the Steam application on the desktop. The process is the same as if you were on a PC.
