ToolRecipe Texture Atlas Packer review
A free browser utility for straightforward texture atlases and UV-coordinate export.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
ToolRecipe Texture Atlas Packer is a free, browser-based utility for combining images or sprites into a texture atlas. It is aimed at solo users and small teams who need a PNG sheet plus machine-readable image positions and UV coordinates. The browser tool processes files locally and states that images are not uploaded. Its scope is focused: it places images without rotating or resizing them, so it suits basic packing more than workflows that depend on tighter optimization or sprite preparation.
For output and coordinate handling, the packer exports the atlas as PNG and a JSON file with each image’s pixel rectangle and UV coordinates. Users can select glTF or OpenGL UV orientation, adjust padding from 0 to 16 pixels, and enable edge bleed. Atlas maximum-size options are 2048, 4096, or 8192 pixels; power-of-two sizing is optional. The interface also shows atlas fill and estimated uncompressed video memory use, and reports when the selected maximum size is insufficient. These options cover common export needs without extending into more advanced packing controls.
This is a practical choice when the goal is one atlas and straightforward metadata export, especially for a browser-based workflow with no separate installation. It is a weaker fit if a project needs automatic trimming, rotation packing, multiple atlases, or animation support; those capabilities are outside its stated scope. Choose it for basic texture atlases with UV-coordinate export, and look for a broader sprite-sheet tool when packing efficiency or animation workflow matters more than a simple PNG-and-JSON result.
