Code to Image

This free code to image tool turns a snippet into a polished, syntax-highlighted picture for X, LinkedIn, blogs and slides. Paste your code, pick a language and theme, and download a 2× PNG with window chrome, line numbers and an optional filename. Highlighting runs locally in your browser — your code is never sent anywhere.

How to use this tool

  1. Paste your code

    Drop the snippet into the editor and pick its language — JavaScript, PHP, Python, HTML, CSS, SQL or JSON.

  2. Pick a theme and style

    Choose one of four themes, toggle line numbers, set the padding and optionally show a filename in the window title bar.

  3. Download the PNG

    Export at 2× resolution or copy the image straight to your clipboard for pasting into a post.

Questions people ask

How do I convert code to an image for free?

Paste the code into the editor, pick the language and a theme, and click Download — no signup, no watermark lock-in (the small credit is a toggle), and no upload of your code.

Which programming languages are supported?

Seven, honestly: JavaScript, PHP, Python, HTML, CSS, SQL and JSON. The highlighter tokenises strings, comments, numbers, keywords and function names for each — we would rather do a handful of languages correctly than claim two hundred.

Is my code uploaded to a server?

No — tokenising and rendering both happen in your browser on a canvas. The page makes zero network requests with your code, which matters if the snippet comes from a private codebase.

Can I get retina-quality exports?

Every download renders at 2× pixel density with a proper monospace stack, so the code stays sharp when X or LinkedIn scales the image in the feed.

What happens to very long lines?

Lines longer than about 110 characters are wrapped before rendering so the export never clips code off the right edge. For social posts, shorter lines read far better anyway.

Can I show a filename on the image?

Yes — type it in the filename field and it appears centred in the macOS-style title bar, which is a nice cue for readers about what they are looking at.
