#image

A fast, fully-local SVG generator for mockups and UIs: placeholder images (a sized rectangle with centered text and automatic contrast), initials avatars (with a deterministic colour derived from the name, in a circle or square), and identicon-style symmetric patterns generated deterministically from any seed. Every endpoint returns the JSON envelope or, with raw=1, the raw SVG so the URL can be used directly as an image source. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for prototypes, dashboards, user avatars, empty states and design systems.

Inspect image metadata (dimensions, format, size, colour space, transparency) and resize or convert images between JPEG, PNG, WebP and AVIF straight from a URL. Perfect for thumbnails, format optimisation and on-the-fly image transforms.
