Paste code, pick a theme, download a clean PNG - no syntax highlighting gimmicks that get languages wrong, just a crisp, readable snippet.
The snippet is rendered directly onto an HTML canvas: the canvas width is sized by measuring the widest line of code with the 2D context's measureText(), a rounded rectangle is drawn for the card background, three colored dots fake macOS-style window controls, and each line of code is drawn as plain text at a fixed line height — there's no real syntax highlighting, so keywords aren't colored differently from the rest. Downloading calls the canvas's toBlob() method to export the whole thing as a PNG.
