When you share code in slides, blog posts, social media or tutorials, a plain system screenshot often comes out with tiny text, a cluttered background and editor UI mixed in with the code. This generator places your snippet in a clean window frame with syntax highlighting, a gradient background and macOS-style traffic-light buttons, so readers focus on the code that matters.
You can choose between three themes, Monokai, VS Dark and GitHub Light, and five highlighting modes: JavaScript, HTML / XML, CSS, Python and JSON. Padding controls the space between the window and the edge of the background; give social posts generous padding so the composition breathes. Corner radius can be tuned to match your brand. Light themes usually read better on projectors and in print, while dark themes suit screens and social feeds.
The PNG is rendered at 2× resolution, so it stays sharp on Retina displays, when enlarged in a presentation and after social platforms recompress it. For readability, keep one image to about 10–25 lines and roughly 80 characters per line, trim unrelated imports and comments, and shorten long strings with an ellipsis. If people need to copy the code, also share a text version or a Gist link, because images are not indexed by search engines or read aloud by screen readers.
Everything is drawn on an HTML canvas in your browser, and the code you paste is never uploaded, so internal or unreleased code is safe to use. Do double-check that no API keys, passwords, internal URLs or personal data appear in the image before you share it.
The PNG is drawn at twice the on-screen size, which keeps it crisp on Retina screens, in slides and on social media.
JavaScript, HTML / XML, CSS, Python and JSON. You can paste other languages, but they will not get language-specific colouring.
On projectors and in bright rooms, GitHub Light is usually easier to read. For screen sharing or social posts, Monokai or VS Dark look great.
No. The image is generated on a canvas in your browser. Still, check that no secrets or passwords are visible before sharing.
