Split 1-2-3

Split 1-2-3이란?

Split 1-2-3 is a fluid, mosaic-style macOS app for multi-image composition. Start with grid templates and break free from rigid alignments using independent horizontal or vertical split adjustments. Each interactive cell acts as a canvas—drag and drop photos, then scale, pan, and frame fractional slices inside a staggered geometric grid. Perfect for mood boards and graphic art, then export high-resolution compositions directly to disk.
