Code Image Generator

Code Image Generator turns a snippet of source code into a polished, shareable image card — the kind of syntax-highlighted graphic you see in conference slides, blog posts, and social threads. You paste your code, pick a language and theme, and it renders the result as a clean card with proper highlighting, a title bar, and padding, exporting to both crisp SVG and raster PNG.

The renderer applies a syntax highlighter so keywords, strings, comments, and numbers get distinct colors based on the language you select, then frames the code in a window-style container with optional traffic-light dots, line numbers, and a background. SVG output keeps the text as vectors, so it stays razor-sharp at any zoom and remains editable, while PNG gives you a ready-to-paste bitmap for platforms that don't accept SVG. Because rendering is done locally, your code never gets sent to a server.

The obvious use case is sharing code on social media or in documentation where a screenshot would look amateurish — a themed card reads as intentional and is far more legible. It's also handy for slide decks, README hero images, changelog announcements, and tutorial thumbnails. For terminal output specifically, reach for the Terminal Screenshot Generator, and for visualizing changes between two versions, the Diff Image Generator.

Practical tips: keep snippets short — roughly 10 to 25 lines reads best as an image, since anything longer becomes unreadable when scaled into a feed. Choose a dark theme for social posts and a light theme for printed or light-background docs, and prefer the SVG export when the image may be enlarged on a projector or retina display so the text never pixelates.
