ImageSlicer

What it does

Automatically detects and isolates individual elements from an image — letters, icons, sprites, or any collection of shapes on a solid background. Supports both gap-scan (whitespace detection) and connected components (blob detection) modes.

How to use it
  1. Drop or open an image (PNG, JPG, WEBP)
  2. Choose Components for touching elements (letters, icons), or Rows/Columns/Grid for whitespace-separated content
  3. Adjust brightness threshold, merge distance, and padding
  4. Download individual slices or all at once as a ZIP
Features
  • Adjustable brightness threshold (what counts as "empty")
  • Connected Components mode — finds isolated blobs even when touching
  • Merge distance — fuses interior holes (B, D, O, P, etc.) into one component
  • Minimum blob area filter to remove noise/dust
  • Horizontal, vertical, or 2D grid slicing (gap-scan modes)
  • Live preview with cut-lines and bounding box overlay
  • Per-slice download + download all as ZIP
  • Optional padding around each slice
