How it works & tips

VectorDeck draws every wallpaper from scratch in your browser. Here's how to go from a blank screen to a wallpaper on your handheld, plus a few tips for getting results you'll actually want to keep.

Making a wallpaper, step by step

  1. Pick your device. The tabs at the top of the generator set the canvas to your screen's native resolution, so the image fits without cropping or scaling.
  2. Choose a style. There are 13 styles, from soft gradients to circuit boards. On desktop, hover over a style to see a short description.
  3. Set the colors. Start from one of the 6 palettes, then fine-tune individual colors with the custom color pickers.
  4. Adjust complexity. This slider controls how dense the pattern is: more shapes, lines or detail as you slide it up.
  5. Reroll until it clicks. Randomize keeps your style and colors but generates a new layout. Surprise Me picks a random style, palette and complexity all at once.
  6. Save or download. Save adds it to your Favorites, and Download exports it as PNG, WebP or SVG.

The styles

  • Aurora Gradient: Soft blended color blobs, like a futuristic aurora.
  • Mandala: Radially symmetric kaleidoscope patterns.
  • Lightcycle: Procedural PCB-style traces with glowing nodes, Tron lightcycle grid vibes.
  • Flow Field: Organic noise-driven flow lines.
  • Galaxy: Swirling spiral arms, a glowing core, scattered stars, and the odd planet.
  • Orbs: Scattered translucent circles, rings, and connecting lines in a molecular-diagram look.
  • Lightning: Branching electric bolts with a glowing charge.
  • Carbon Fiber: A woven carbon-fiber weave, diagonal threads with a tinted sheen.
  • Hive: A symmetrical honeycomb of evenly sized cells. Complexity sets the cell size.
  • Silicon Chip: Rectilinear die blocks with fanned-out bus traces for a defined, chip-die look.
  • Matrix: Falling columns of letters, numbers, symbols, and katakana with a glowing lead character per stream.
  • Waves: A smooth vertical gradient crossed by soft wave lines, each its own wavelength.
  • Abstract Shards: A faceted mesh of low-poly triangle shards, each catching the light a little differently.

Some styles have extra options that appear next to the palettes, like the number of mirror segments in Mandala, the trace style in Lightcycle, or the cell shape in Hive. It's worth trying each one, because they change the look far more than a reroll does.

Tips for a better wallpaper

  • Leave room for your icons. Home screens draw menus, icons and text on top of the wallpaper. A lower complexity setting keeps the background calmer and the menus easier to read.
  • Keep the base color dark. Every built-in palette starts with a deep background color. On small, bright handheld screens, a dark base makes the accent colors pop and is easier on the eyes at night.
  • Pick accents that contrast. When customizing colors, pair a warm accent with a cool one (pink with cyan, gold with blue) rather than two similar shades. The glow and line effects stand out much more.
  • Reroll before you retune. If a design is almost right, hit Randomize a few times before changing colors or complexity. A new seed often fixes an awkward layout on its own.
  • Start from the gallery. The Gallery has ready-made designs for every device. Hit Edit on one to load its exact settings into the generator and make your own variation.
  • Save the ones you like. A saved favorite remembers its exact settings, so you can come back later and download it for a different device or format.

Choosing the right format

Use PNG if you're unsure; it's lossless and supported almost everywhere, including the PSP and Miyoo Mini. WebP gives a smaller file with the same look, which is handy for Android-based handhelds like the Logitech G Cloud. SVG is a vector file that stays sharp at any size, so it's the pick for large monitors or further editing, though most handhelds can't set it as a wallpaper directly.

Setting it as your wallpaper

Download the wallpaper for your device's tab, then:

  • PSP (480×272): connect the PSP over USB (or put the Memory Stick in a card reader) and copy the PNG into the PICTURE folder at the root of the stick. On the PSP, open it under Photo, press △ and choose Set as Wallpaper.
  • Steam Deck: in Desktop Mode, right-click the desktop and choose Configure Desktop and Wallpaper. Changing the Game Mode background isn't supported natively, but plugin loaders such as Decky Loader offer community plugins that can.
  • ROG Ally: it runs Windows, so right-click the downloaded image and choose Set as desktop background, or go to Settings → Personalization → Background.
  • Miyoo Mini: with a custom firmware like Onion OS, themes live in the Themes folder on the SD card. Replace a theme's skin/background.png with your 640×480 PNG, then select that theme on the device.
  • Logitech G Cloud: it runs Android, so open the image in your gallery or photo app and use Set as wallpaper, or long-press the home screen and choose Wallpapers.

Keeping your designs safe

Favorites live only in the browser you saved them in. Every so often, use Export JSON on the Favorites page to back them up. You can import that file on any device, or use Download All (ZIP) to save every favorite as an image. More answers are in the FAQ.
