Sprite Sheet Cutter

How To Use

Drop a sprite sheet image below, or click to pick a file.
Set Frame W/H. If the sheet isn’t perfectly grid-aligned, enable Trim and tune Alpha.
Align the grid with Grid Offsets or the Pick Origin button in the preview header. Hold Shift while picking origin to set a fine within-frame offset.
Toggle Selection Mode in the preview header to choose frames: - Drag to add; hold Option/Alt (or Cmd) to subtract. - Shift-click selects a range; click toggles a single frame.
Preview controls: Overlay toggles boxes. Zoom slider sits next to the preview; use +/- keys. Hover a box to see index/coords; press C or use Copy to grab the info.
Exports: ZIP (all/selected), Metadata JSON, TexturePacker JSON, and Atlas Repack (PNG+JSON). Use the ZIP option for atlas to get both files together. Filename pattern supports {i}, {row}, {col}, {x}, {y}, {w}, {h}
Modal: Click a frame to preview. Use ←/→ to navigate; Esc to close.
Performance: Fast blank check samples pixels to skip blanks faster on large sheets.
