Texture Atlas Packer

TEX2ATL

Pack loose textures into optimized atlases with engine-ready metadata.

About

Drag in a pile of textures (or a whole folder) and it bin-packs them into a tight power-of-two atlas, then exports the sheet plus coordinate data for your engine.

Key features

MaxRects packing — automatic best-fit sizing for high occupancy and minimal wasted space.
Auto-split — spills into multiple sheets when everything won't fit.
Edge extrude / gutter — kills texture bleeding at atlas seams.
Metadata for every pipeline — generic JSON (pixel + normalized UVs for 3D UV-remapping), Unity & Unreal (TexturePacker JSON), and Godot (.tres AtlasTexture).
Live preview — pan and zoom, hover to inspect any sprite's name and dimensions.
Broad format support — PNG, JPG, WebP, and TGA, with recursive folder import.

How it works

Drop textures, pick a metadata format, and export the atlas plus data file.
