Configure your multi-monitor setup, upload a panoramic image, and download pixel-perfect PNGs — cropped precisely to each screen. No accounts. No servers.
Your images never leave your device
Define any number of monitors with exact pixel dimensions, positions, and DPI scale factors. Supports mixed-resolution setups.
See exactly how your wallpaper will map across your virtual desktop in real time. Drag monitors to reposition them on the fly.
Get all your monitor slices in a single ZIP archive — clearly labeled monitor-1.png, monitor-2.png, and so on.
Choose between Fill (crop to cover, no letterboxing) or Fit (letterbox to preserve the full image).
Instantly load common configurations: Dual 1080p, Dual 4K, Triple 1080p. Or build a completely custom layout from scratch.
All image processing happens on your machine using the Canvas API. Your wallpapers are never uploaded anywhere — not even temporarily.
Enter each monitor's resolution and position. Use a preset or drag to arrange them to match your physical desk.
Drop a JPEG, PNG, or WebP. The live preview instantly shows how it maps across your virtual desktop.
Hit the button — the app crops each monitor's slice in the browser and packages them into a ZIP in seconds.
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.
No sign-up. No install. Just open and go.
