When a Code Image Beats a Code Block

Most social platforms destroy pasted code — indentation collapses, line breaks vanish, and smart quotes replace the real ones. An image sidesteps all of that and renders identically everywhere, which is why code screenshots became the norm for sharing snippets on X and LinkedIn.

The trade-off is real though: nobody can copy from an image, and screen readers cannot read it. Use an image when the code is being shown, and a gist or fenced code block when it is meant to be used.

Highlighting here is deliberately heuristic rather than language-specific. It detects strings, comments, numbers, function calls, and a keyword set spanning the common languages — accurate enough to read well in a screenshot without shipping a megabyte-scale parser for something that is ultimately decorative.

Frequently Asked Questions

What is this for?

Sharing code where a plain text paste would be mangled — X, LinkedIn, Slack, slides, blog headers, or documentation. An image preserves the formatting and colouring exactly.

Which languages are supported?

Highlighting is heuristic rather than language-specific: it recognises strings, comments, numbers, function calls, and a keyword set covering JavaScript, TypeScript, Python, Go, Rust, Java, C-family, PHP, and SQL. That is accurate enough for a screenshot without shipping a full parser.

Why can I not copy text out of the image?

That is the trade-off with any code screenshot. If readers need to copy the code, share a gist or code block instead — an image is for visual impact, not reuse.

What resolution is the download?

Rendered at twice the preview size so it stays crisp on high-density displays and when scaled down in a feed.

Is my code uploaded?

No. Everything is drawn on a canvas in your browser and the PNG is generated locally. Nothing is sent to a server.
