  • Paste, type, or drag a code file onto the canvas. The language is detected automatically from the file extension.
  • Style it with the control panel: theme, background, font, size, padding, window chrome, and title.
  • Add line numbers, highlight specific lines (e.g. 3,7-9), trim to a line range, or show a diff — manual marks or a computed GitHub-style diff against an original.
  • Export PNG (1x, 2x, or 3x) or true-vector SVG. Free exports carry a small watermark.
  • Use "Copy link" to share — the full snippet state is compressed into the URL.
