Watch raw AI art become a clean, aligned game tileset.

How it works

From rough sheet to usable tileset.

Tileset Forge handles the practical cleanup work between a beautiful generated image and a real game asset: detection, chroma cleanup, edge repair, grid testing, map preview, and export.

STEP 01

Detect tiles from rough sheets

Upload an AI-generated sheet, concept image, or messy tileset and let Tileset Forge identify connected tile components. It can auto-detect the background color, filter by minimum size and aspect ratio, and build a palette of extracted tiles.

  • Automatic background color detection
  • Connected-component tile detection
  • Minimum size and aspect-ratio filtering
  • Multiple source sheets in one project

STEP 02

Clean edges and align every cell

Clean the pixels that usually make AI tiles unusable: background halos, dark transparent edges, odd crop bounds, and uneven cell sizes. Then fit each tile into a clean target size with anchors, stretch modes, overscale, flips, and rotation.

  • Global or flood chroma key cleanup
  • Edge chroma, edge trim, alpha threshold, and edge expansion
  • Fill, fit-width, fit-height, and original fit modes
  • Anchor, nudge, overscale, rotate, and flip controls

STEP 03

Preview maps and export sheets

Test the tiles in a real grid before you export. Paint, erase, clone, marquee-select, copy, paste, and preview square or diamond maps to catch spacing and edge issues before they reach your game.

  • Stamp, erase, clone, marquee, and grid editing tools
  • Square and diamond map previews
  • Project saves for reopening tile work
  • PNG tileset and optional normal-map export

Pipeline

Everything that makes tiles actually usable.

AI can make beautiful tile art. Tileset Forge makes it aligned, cropped, transparent, padded, testable, and ready to import.

Tileset Forge output is plain PNG-based game art, so it can move into practically any 2D engine or map editor.

Common questions

Everything you might be wondering.

Short answers before you open the tool.

01Does Tileset Forge generate the original art?+
Tileset Forge is focused on turning existing art into usable tilesets. You can start with AI-generated art, hand-made art, or rough tile sheets, then detect, clean, align, preview, and export the tiles.
02Can it remove backgrounds from AI tiles?+
Yes. It includes automatic background detection, global and flood chroma key modes, edge chroma cleanup, edge trimming, alpha cleanup, and edge expansion controls.
03Can I preview the tiles before export?+
Yes. Tileset Forge includes a map preview where you can stamp, erase, clone, marquee-select, copy, paste, and test both square and diamond grids.
04What tile sizes are supported?+
You choose the output tile width and height. The tool can fill, fit width, fit height, keep original fit, anchor, nudge, rotate, flip, and overscale tiles into that cell size.
05What does it export?+
It exports clean PNG tileset sheets and can also generate optional normal maps. Projects can be saved so you can reopen and keep adjusting the tiles.
06Why does edge padding matter?+
Edge padding fills transparent pixels near opaque tile edges with nearby color, which prevents dark outlines or filtering artifacts in engines like Unity, Godot, and Unreal.
