Code to Image
Paste code, pick a theme and background, and download a shareable screenshot card as a high-resolution PNG.
Rendered on your device — your code is never uploaded.
Options
How it works
- Paste your code into the editor and choose its language so keywords, strings, and comments get colored.
- Pick a theme and a background, add an optional window title, and adjust font size, padding, and line numbers under Options.
- Check the live preview and click Download PNG to save the card at 2x resolution.
Frequently asked questions
- How does the syntax highlighting work, and how accurate is it?
- The tool uses lightweight regex tokenizers that recognize keywords, strings, comments, and numbers for JavaScript, TypeScript, Python, HTML, CSS, and JSON. It is deliberately approximate — a full parser would be overkill for a screenshot — so rare constructs like nested template literals may be colored imperfectly. For a shareable image the result is indistinguishable from editor highlighting in almost all cases.
- Is my code uploaded anywhere when I generate the image?
- No. The card is drawn on an HTML canvas entirely inside your browser, and the PNG is assembled locally when you click download. Nothing is transmitted or stored on a server, so the tool is safe to use with proprietary or unpublished code.
- What resolution is the downloaded PNG, and does it have a watermark?
- The image is rendered at 2x pixel density, so text stays sharp when the card is zoomed, embedded in slides, or viewed on high-DPI screens. There is no watermark, logo, or attribution added anywhere on the image — the card contains only your code and the chrome you configured.
- Can I make the background transparent instead of a color or gradient?
- Yes. Choose the transparent option in the background selector and the PNG will keep an alpha channel outside the code card. That lets you drop the card onto any slide, document, or website background without a visible rectangle around it.
- What is this useful for compared to a normal screenshot?
- A plain screenshot inherits your editor’s window size, cursor, and UI clutter, and it is often blurry after cropping. This generator produces a clean, consistently padded card at exact 2x sharpness, which works better for social media posts, blog thumbnails, documentation, slides, and code review discussions.
About this tool
Code to Image turns a pasted snippet into a polished screenshot card: a rounded window with traffic-light dots, an optional title, syntax-highlighted code, and a background of your choice. It replaces the usual workflow of arranging an editor window, taking a screenshot, cropping it, and hoping the result is sharp enough — instead you get a consistent, watermark-free PNG in a few seconds.
Everything happens client-side. Your code is tokenized with small regex-based highlighters for JavaScript, TypeScript, Python, HTML, CSS, and JSON, then drawn onto a canvas element at 2x pixel density. Because no parser or server is involved, the preview updates live as you type, and the code itself never leaves your device — a real consideration when sharing snippets from private repositories. The highlighting is intentionally approximate: it colors keywords, strings, comments, and numbers reliably, which is what the eye reads on a card, without attempting full language analysis.
Typical uses include posting a snippet on social media where plain text loses formatting, creating thumbnails for programming articles and videos, embedding readable examples in slide decks, and sharing a bug or a neat trick in a chat where an image travels better than a gist link. The transparent background option is handy for slides and dark-mode websites, while the gradient backgrounds give standalone posts some visual weight.
A few practical tips: keep snippets under roughly 25 lines so the text stays large enough to read on a phone timeline; use a light theme when the image will sit on white documentation pages; and set the window title to a filename such as app.ts to give viewers instant context. If a line is very long, the card widens to fit it, so breaking long lines before generating produces a more compact, more legible image.
