Free Game Dev Tools
The texture chores between your art tool and your engine: pack the sprites, bake the normals, combine the maps, build the skybox.

Sprite Sheet PackerPack loose PNG sprites into one texture atlas with a JSON, XML or Godot coordinate map. Trim, pad and extrude in your browser, with no uploads.
Normal Map GeneratorTurn a height map or any texture into a tangent-space normal map. Adjust strength, pick OpenGL or DirectX and keep it tileable, all in your browser.
Texture Channel PackerCombine metallic, AO, roughness and smoothness maps into the RGBA channels of one texture. Presets for Unity HDRP, URP and ORM. Runs in your browser.
Cubemap Texture GeneratorBuild a Unity skybox cubemap from six face images. Exports strip and cross layouts in your browser.About these tools
Game engines are picky about textures. Unity wants smoothness in the alpha channel of a mask map, Unreal wants a DirectX normal map with roughness in green, Godot wants an ORM texture, and every 2D engine wants its sprites on one sheet with a coordinate file. The art itself is done; what is left is plumbing between formats.
These tools cover that step. The sprite sheet packer turns a folder of PNGs into one atlas with JSON, XML or Godot resources. The normal map generator converts a height map or a plain texture into a tangent-space normal map in either OpenGL or DirectX convention. The channel packer combines metallic, occlusion and roughness maps into a single texture with presets for Unity HDRP, URP and ORM. The cubemap generator assembles six faces into the layouts engines import as a skybox.
Everything runs on your own device. Unreleased art is not uploaded anywhere, there is no file-count limit and no watermark, and the tools work the same for a jam prototype as for a commercial project.
