MergePNG vs World Labs

MergePNG is a free online tool that combines PNG, JPG, and WebP images into a single file or PDF, all directly in your browser. It prioritizes privacy by processing everything offline on your device, ensuring no uploads, no data leaks, and preserved transparency. Effortlessly drag, reorder, choose from various layouts (stack, side-by-side, grids), and customize with borders or rounded corners. Perfect for creating collages, sprites, or consolidating screenshots without installing any software or worrying about server-side privacy risks.

World Labs is pioneering spatial intelligence through its flagship product, Marble. Move beyond 2D pixels into persistent, high-fidelity 3D worlds generated from text, images, or video, designed for creators to inhabit and edit.
