How to Add a Non-Steam Game to Your Steam Library

Add an installed game or application to your Steam Library as a shortcut on desktop or Steam Deck.

Free tools Windows power users keep installed

One-click scans. No signup required.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

In Steam’s desktop client, open Games > Add a Non-Steam Game to My Library, select an installed game from the list or browse to its application, then click Add Selected Programs. This creates a shortcut in Steam; it does not make Steam deliver the game’s updates or establish that you own it on Steam.

Add a non-Steam game in the desktop client

  1. Launch Steam.
  2. Open the Games menu and choose Add a Non-Steam Game to My Library.
  3. Select the checkbox beside a game shown in the list, or use the browse option to locate the installed game on your computer.
  4. Click Add Selected Programs. The game will appear in your Steam Library as a shortcut.

Steam also identifies the lower-left + ADD A GAME… button as another entry point; choose Add a Non-Steam Game… there. See Steam Support’s instructions for adding non-Steam games.

Add an installed application on Steam Deck

On Steam Deck, add the application from the desktop version of Steam:

  1. Press the Steam button, open Power, and select Switch to Desktop.
  2. Open the Steam client on the desktop and click Add a Game in the lower-left corner.
  3. Choose Add a Non-Steam Game, select the installed application, and add it.
  4. Return to gaming mode using the desktop’s Return to Gaming Mode link. The application should appear in the Library’s non-steam tab.

These Deck steps are documented in Steam’s desktop FAQ for Steam Deck and Steam Machine.

#1 Best Overall

  • Compatible with Windows and Android.

What the shortcut does—and does not do

Adding the entry lets you launch the game or application from Steam’s client. It does not add the game to Steam’s update delivery, and it does not count as proof of ownership for your Steam account. The game or application needs to be installed on the computer or Deck; adding it this way is not a way to download it through Steam.

Launch options are a separate setting

You do not need to set launch options to add a shortcut. If a particular game requires supported launch parameters, open it in the Library, right-click it, choose Properties, then enter them under General > Launch Options. Steam’s documented common options apply to GoldSrc and Source engine games and not to most third-party games; check the game’s own instructions before entering anything. See Steam Support’s launch-options guide.
