✂️ AI Sprite Cutter

AI detects valid sprite regions and auto-slices character sheets, props, and UI icons for faster 2D asset prep.

How to use

  1. Upload a PNG / WebP / JPEG asset (solid-color backgrounds such as white or green screen work best)
  2. Click Smart detect icons to find non-background regions and generate slice boxes
  3. To remove backgrounds: adjust tolerance and feather in the keying panel, fine-tune with pick color or punch mode, then click Apply keying
  4. Box-select, move, or delete slices on the canvas; use Trim selected or Trim all to crop transparent edges
  5. Download individual PNGs or a slices ZIP from the results panel, or Send to texture packer to build an atlas
  • Scroll wheel to zoom; right-click or hold Space to pan the canvas
  • Drag on empty canvas to add a slice; toggle Auto snap at top-right; Delete removes the selection; Ctrl+Z undoes the last box select or delete
  • Collapse this panel from the header when you no longer need the walkthrough

AI Sprite Cutter — overview

AI Sprite Cutter helps indie devs detect regions in character sheets and UI sprites, then export PNG sequences or send slices to the texture packer—without manual Photoshop boxing.

Why AI helps

Manual frame boxing is slow and error-prone. AI-assisted detection finds valid regions faster so you can focus on gameplay.

Use cases

  • • Split character action sheets
  • • Batch UI icons
  • • White-background detection
  • • Handoff to texture packer

How to improve asset efficiency

  • • Normalize white backgrounds before upload
  • • Fine-tune boxes after smart detection
  • • Send slices to the packer in one flow
  • • Match Unity/Cocos/Godot workflows

Supported formats
