Open tool →About these tools
Every tool here started as a real problem in a real project: a normal map that looked inverted in Unreal, a mask map packed in the wrong order for Unity, a dozen Steam images due the night before a festival, an economy that felt wrong but nobody could say why.
Made for Unreal Engine and Unity
The two engines disagree on many small things: DirectX versus OpenGL normal maps, ORM versus mask maps, centimeters versus meters, Z-up versus Y-up, DataTables versus JSON. Wherever they differ, the tools give you the exact format your engine expects.
Private by design
Calculators and generators run entirely in your browser. File tools marked Cloud process your files on our server in memory and send the result straight back. Nothing is stored, shared or used for anything else.
Free, with no catch
No account, no watermark, no daily limit for normal use. The tools are how we give back to the community and how developers discover our plugins and assets.
