Code to Image

Turn a code snippet into a polished, syntax-highlighted PNG card in your browser, with a theme, gradient or transparent background, and padding — no upload.

Loading tool…

Code to Image — Paste a snippet, pick its language, theme, background and padding, and export a Carbon-style code card as a transparent or gradient-backed PNG. Syntax highlighting and the image capture both run entirely in your browser with Prism and html-to-image, so your code is never uploaded. The preview updates live as you type or switch options.

What is Code to Image?

Code to Image is a free, browser-based tool that turns a code snippet into a shareable picture — a styled, syntax-highlighted code card you can drop into a blog post, slide deck, README, or social post. It is popular with developers, technical writers, and educators who want their code to look intentional instead of pasting a flat screenshot. Choose from JavaScript, TypeScript, JSX, CSS, HTML, JSON, Python, or Bash highlighting, then dress the card with a theme, a gradient or solid background, and your preferred padding. The card renders live as you edit, and a single Download PNG button exports it at 2x resolution.

How to use Code to Image

  1. Paste or type your code into the editor, or connect another tool's text output to the input port in the workspace.
  2. Choose the matching language — JavaScript, TypeScript, JSX, CSS, HTML, JSON, Python, or Bash — so the syntax highlighting is correct.
  3. Open Settings to pick a theme (Midnight, Graphite, or Snow), a background (Aurora, Sunset, Ocean, Slate, or Transparent), and the padding (Cozy, Normal, or Roomy).
  4. Watch the live preview update as you type and change options; click it to enlarge it in the zoom view.
  5. Press Download PNG to save the card as a high-resolution image, or, in the workspace, feed the PNG straight into an image tool downstream.

Examples

A JavaScript function for a blog post

Paste a short JavaScript function, keep the language on JavaScript, pick the Midnight theme with the Aurora gradient background, and download a crisp PNG to embed in an article instead of a flat screenshot.

A transparent CSS snippet for slides

Switch the language to CSS and the background to Transparent so the exported PNG has no backdrop, letting the code card sit cleanly on a colored slide background.

A Bash command card for a README

Select Bash, choose the Snow light theme with the Slate solid background and Roomy padding, and export a clean, readable command card for your project's documentation.

Frequently asked questions

Which languages can it highlight?
It highlights JavaScript, TypeScript, JSX, CSS, HTML, JSON, Python, and Bash. Pick the one that matches your snippet from the language dropdown; if a token cannot be classified it simply falls back to the base text color.
What image format does it export?
It exports a PNG at 2x pixel density for sharp results. If you choose the Transparent background option, the PNG keeps an alpha channel with no backdrop behind the code card.
Can I change the look of the card?
Yes. In Settings you can switch between the Midnight, Graphite, and Snow themes, choose an Aurora, Sunset, Ocean, Slate, or Transparent background, and set Cozy, Normal, or Roomy padding around the code.
Is my code uploaded anywhere?
No. Both the syntax highlighting (Prism) and the image capture (html-to-image) run 100% client-side in your browser. Your code is never uploaded, sent to our servers, or shared, so even proprietary snippets stay on your device.
Why doesn't the image appear until I click Download on the tool page?
On the standalone page the PNG is rendered when you press Download PNG, so typing doesn't re-capture the image on every keystroke. The styled preview still updates live as you edit; in the workspace the PNG also rebuilds automatically so it can flow to the next tool.
