Plinko

Plinko is a private offline tool for cutting sprite sheets into production-ready PNG frames.

Import a sheet, build an automatic grid, fine-tune every cell, preview the animation, then export frames plus a JSON descriptor — all on device, with no account and no internet permission.

• Import PNG, JPEG, WebP and other Android-supported images via the system picker
• Create, rename, duplicate, favorite, search, sort and filter projects
• Build grids by row/column count or exact frame size
• Set source-pixel margins and spacing
• Zoom, pan and select frames on a precise canvas
• Manually adjust left, top, right and bottom bounds
• Include or exclude individual frames from export
• Undo/redo editing history with automatic save
• Preview animation from 1–60 FPS
• Export numbered PNG frames and sprites.json
• Local metadata backup and restore
• Light, dark and system themes
• English and Russian UI

Designed for pixel artists and game developers who want a focused workbench without cloud lock-in. Source images stay on your device; the app never requests broad storage or network access.
