Mac

Smart-select tiles from a sheet, trim and erase as needed, then export PNGs or atlas+JSON. Local Mac tool for game and anime art pipelines. A Mac tool for atlas / sprite-sheet splitting: turn one source image into ready-to-use tiles. Open an atlas, then auto-frame clear sprites; clean edges with the eraser; Trim to Content to fit opaque pixels; remove backgrounds with the wand; or use the grid when tiles are evenly laid out. Check Image Properties when you need them, or save a Freehand region on its own. Export locally and drop the results into your project. What you can do • Auto Frame: click the background to frame clearly separated sprites • Eraser: hard square brush (1–16 px) clears alpha; undo supported • Trim to Content: tighten the selection to opaque pixels • Remove background: wand selection, then make transparent • Grid split: cell size, columns/rows, margin, and spacing • Freehand frames: draw boxes for irregular layouts • Crop leftover edges, or pad with transparency • Filename templates—rename, then batch export • Export loose tiles as PNG / JPG / BMP to a folder • Or export an atlas image plus JSON frame data • Save a sprite/region to disk • No account, no upload—everything stays on your Mac Built for game and animation work, UI / icon sheets, pixel and 2D asset cleanup, and anyone who needs a fast local “one image → many tiles” export on Mac.A lightweight local tool for fast slicing and light cleanup—not a full drawing app. Auto Frame works best on transparent backgrounds with clearly separated sprites. If sprites touch or the background is noisy, switch to Freehand, the eraser, or the wand.
