What Is the PNG Cube Generator?
The PNG Cube Generator is a free browser-based tool for building a 3D cube from your own images and exporting it as a single flattened PNG file. It's aimed at designers, teachers, and hobbyists who want a quick way to visualize six related images — like a product from every angle, a set of icons, or a photo collage — as one cohesive cube graphic.
You can upload JPG, PNG, or WebP files for each of the six faces (front, back, left, right, top, bottom). Any face you leave empty can be filled with a randomly generated gradient color instead, so you can start with as few as one image and still get a finished cube.
Because everything runs client-side using the browser's Canvas API, nothing is uploaded to a server. Files are read locally with the FileReader API, composited on an in-memory canvas, and only leave your device when you click download.
Why Trust Web Tools Pro for This Tool?
The tool uses only standard, well-documented browser APIs (FileReader, Canvas, Blob) with no external dependencies, so there's nothing to install and nothing tracking your files. The full logic runs in the page you're looking at right now.

💡 Pro tip: For the best cube result, use images that are roughly square (1:1 ratio) and have similar brightness levels. This helps the cube look balanced when it rotates.
