The Steam Deck is more than a handheld console. It is your portable gaming world. And like any personal device, it feels better when it looks like you. The good news? Adding custom images to your Steam Deck is easy. You can change backgrounds, artwork, icons, and even boot screens. Let’s walk through it step by step and make your Deck truly yours.
TLDR: You can customize your Steam Deck with custom backgrounds, artwork, boot videos, and icons. Most changes can be done in Desktop Mode using simple file transfers. SteamGridDB and basic image editing tools make it easy. With a few tweaks, your Steam Deck can look totally unique.

It is like putting a custom wallpaper on your phone. Small change. Big difference.
Before You Start
You will need a few things:
- Your Steam Deck
- A Wi-Fi connection
- Images you want to use (PNG or JPG works best)
- Optional: USB drive or cloud storage
Most customization happens in Desktop Mode.
To switch modes:
- Press the Steam button.
- Go to Power.
- Select Switch to Desktop.
Your Steam Deck will now look more like a Linux computer. Do not worry. It is simple.
How to Add Custom Game Artwork
This is one of the most popular tweaks. You can replace the game’s cover art, grid image, and even the hero banner.
Step 1: Get the Right Image Size
For best results, use these sizes:
- Grid image: 600 x 900
- Hero image: 1920 x 620
- Logo: Transparent PNG
- Icon: 512 x 512
You can create your own images. Or download them from community art sites like SteamGridDB.
Step 2: Add Artwork in Gaming Mode
- Return to Gaming Mode.
- Find the game in your library.
- Press the Options button (three dots or menu button).
- Select Manage.
- Choose Set Custom Artwork.
Select your image. Done.
It updates instantly. Your library now looks way better.
How to Change the Background
Want a custom background behind your library?
This requires Desktop Mode.
Step 1: Locate the Steam Folder
Open the file browser (Dolphin). Then go to:
/home/deck/.local/share/Steam/
If you do not see hidden folders, enable them:
- Click the menu.
- Select Show Hidden Files.
Step 2: Add Your Image
You can replace certain library assets manually. Some users install CSS loader tools to fully customize themes.
If you want an easier method, use a Steam Deck plugin manager like Decky Loader.
Using Decky Loader for Easy Customization
Decky Loader is a plugin system. It makes customization simple. No deep coding needed.
With it, you can:
- Install themes
- Change background images
- Add sound effects
- Modify UI colors
How to Install Decky Loader
- Switch to Desktop Mode.
- Open a browser.
- Download Decky Loader from its official site.
- Run the installer.
Once installed, switch back to Gaming Mode. You will see a new plugin icon in the quick access menu.
From there, you can browse themes and apply them instantly.
This is the easiest way to change backgrounds without digging through folders.
Add a Custom Boot Video
This is one of the coolest tricks.
Imagine turning on your Steam Deck and seeing your favorite game intro.
Where Boot Videos Are Stored
Boot videos are located in:
/home/deck/.steam/root/config/uioverrides/movies/
If the folder does not exist, create it.
How to Add the Video
- Format must be WEBM
- Name it appropriately (like deck_startup.webm)
- Place it in the movies folder
You can download ready-made boot animations online. Or create your own using video editing software.
Keep it short. Around 5 seconds works best.
Restart your Steam Deck. Enjoy your custom startup.
Customize Non-Steam Games
Adding emulators or non-Steam games?
They often show blank or ugly artwork by default.
You can fix that.
Step 1: Add Game to Steam
- Open Steam in Desktop Mode.
- Click Add a Game.
- Select Add a Non-Steam Game.
- Choose your app or emulator.
Step 2: Add Custom Art
Right-click the game.
Select Manage.
Apply custom artwork just like any other title.
This makes your emulation library look clean and professional.
Best Image Tips for Clean Results
Bad images ruin good setups. Follow these simple rules:
- Use high resolution images.
- Avoid stretched artwork.
- Match the correct aspect ratio.
- Use transparent PNGs for logos.
- Keep file sizes reasonable.
If your image looks blurry, it is likely too small.
Bigger is better. As long as proportions are correct.
Organizing Your Custom Images
Things can get messy fast.
Create a folder structure like this:
- SteamDeckCustom
- Grid Art
- Hero Images
- Logos
- Boot Videos
This makes future changes easy.
You will thank yourself later.

Boot Video Not Playing?
- Ensure it is WEBM.
