SpriteTailor

Prepare your artwork with precision. SpriteTailor combines edge-alpha blending, individual image adjustments, and editable polygon selections with sprite slicing, trimming, resizing, and texture atlas packing. EDGE-ALPHA BLENDING Control how image edges fade into transparency to prepare tiles and sprites for smoother blending. Adjust edge-alpha settings and feathering to soften boundaries without having to edit every edge by hand. ADJUST INDIVIDUAL SELECTIONS Fine-tune selected images and slices with easy-to-use saturation, brightness, sharpness, and contrast sliders. Adjust individual assets independently, or apply the same adjustments across multiple images for a consistent look. PRECISE POLYGON CUTOUTS Go beyond rectangular slicing. Place polygon points around difficult boundaries, then drag the points to refine your selection before applying it. Isolate tightly packed artwork and remove neighboring fragments that a rectangular crop would include. SLICE AND REFINE Detect sprites in transparent PNG sheets, split connected regions, erase unwanted pixels, restore details, merge pieces, and remove unwanted slices. Export isolated, tightly trimmed PNGs. TRIM, RESIZE, AND PACK Batch-process PNGs with configurable padding and output scales. Build texture atlases with recommended layout settings, then customize dimensions, grids, padding, and alignment. Export PNG atlases, Tiled TSX tilesets, and JSON project data. SAVE YOUR PROGRESS Save editable slicing projects—including unfinished polygon outlines—to continue complex refinements later. Import artwork from your files or Photos and create new outputs without overwriting your original images. Built for game developers and artists on Mac, iPad, and iPhone.
