Sphere
Free PNG images in the category “Sphere”: 20 files with transparent background, no sign-up.
Round forms of every scale: a magenta sphere built from a fine geodesic mesh, Jupiter with its pale cloud belts, a school globe on a curved metal stand, a scatter of blue water beads with bright highlights. Flat circles ride along too: a watercolour disc, a rough ink ring, a round seascape badge.

Sphere in the Abstract section
Abstract holds pure shapes. Circle is flat, drawn on the page; Sphere has volume, shown by light and shade across a curved surface. Polygon and low poly break the surface into facets, and liquid gives it a surface that moves. In practice the category also picks up planets and globes, because they are spheres too.
Geometry, science, decoration
The geodesic mesh suits technology headers and abstract layouts where a solid ball would look heavy. Jupiter and the globe belong to astronomy and geography, lesson slides and planetarium pages. The water beads work as a fresh texture for cosmetics or drinks, scattered behind a product.
Light direction matters
A sphere shows where the light comes from. When combining several, choose ones lit from the same side, otherwise the arrangement looks pasted together. Glossy highlights are part of the image; on a dark background they read well, on white they can vanish.
