Everything you need,
nothing you don't

Multi-monitor aware

Define any number of monitors with exact pixel dimensions, positions, and DPI scale factors. Supports mixed-resolution setups.

Live canvas preview

See exactly how your wallpaper will map across your virtual desktop in real time. Drag monitors to reposition them on the fly.

ZIP download

Get all your monitor slices in a single ZIP archive — clearly labeled monitor-1.png, monitor-2.png, and so on.

Fill or Fit modes

Choose between Fill (crop to cover, no letterboxing) or Fit (letterbox to preserve the full image).

Quick-add presets

Instantly load common configurations: Dual 1080p, Dual 4K, Triple 1080p. Or build a completely custom layout from scratch.

Completely private

All image processing happens on your machine using the Canvas API. Your wallpapers are never uploaded anywhere — not even temporarily.

Three steps to a perfect setup

1

Configure your monitors

Enter each monitor's resolution and position. Use a preset or drag to arrange them to match your physical desk.

2

Upload your wallpaper

Drop a JPEG, PNG, or WebP. The live preview instantly shows how it maps across your virtual desktop.

3

Split & download

Hit the button — the app crops each monitor's slice in the browser and packages them into a ZIP in seconds.

Your images stay on your machine

SliceScreen is a purely client-side app. All cropping happens in the browser via the Canvas API — no files are ever transmitted to any server. There's no backend, no storage, and no account required.
