Image Sheet Slicer
Upload a sheet containing images, icons, symbols or cards. They get detected automatically, or draw the boxes yourself. Export them as uniform squares, shared grid cells or original crops, ready to copy straight into Vector Painter or Pixel Painter, or download the whole set at once. Nothing is uploaded.

{{ boxes.length }} box{{ boxes.length===1?'':'es' }} found. Drag a box to move it, drag a corner or edge to resize, drag on empty space to draw a new one, or click a sliced image below to select and fine-tune it here.
Detection
Higher sensitivity includes faint and low-contrast pixels. It affects automatic boxes only and applies after you pause.
Turn off to preserve a manually drawn box exactly, including its original margins and background.

Result
What this does. Detects separate items on an uploaded image or sprite sheet by isolating shapes against the background, then exports them as uniform squares, shared rectangular grid cells or literal original crops. Detection is a starting point, not a requirement: drag, resize, add or delete boxes by hand at any time, and padding/upscale changes redraw the results immediately.
Everything happens in your browser tab. The sheet you upload is never sent anywhere.
