What is Code to Image Converter?

Code to Image Converter is a free online tool that transforms your code snippets into beautiful, shareable images. With syntax highlighting from highlight.js, multiple themes, customizable backgrounds, and optional window chrome, you can create professional-looking code images for social media, documentation, presentations, and blog posts.

Sharing code as images has become a standard practice on platforms like Twitter, LinkedIn, and Instagram where proper code formatting is not supported. This tool makes it easy to create visually appealing code screenshots that capture attention and convey your message effectively.

How to Use the Code to Image Converter?

Converting code to images is simple:

  1. Paste your code - Enter or paste your code into the code editor area.
  2. Select language - Choose the programming language for accurate syntax highlighting.
  3. Pick a theme - Select from dark, light, monokai, nord, or GitHub themes to match your preference.
  4. Customize appearance - Adjust font size, padding, toggle line numbers and window bar, and set the window title.
  5. Download the image - Click the Download PNG button to save your code snippet as a high-quality PNG image.

Features

The tool supports 18 programming languages, 5 professionally designed themes, configurable font sizes from 10 to 32 pixels, adjustable padding, line number display, and a macOS-style window bar with custom titles. Images are rendered at 2x resolution for crisp, retina-quality output that looks great on all devices.

Frequently Asked Questions

What languages are supported?

The tool supports JavaScript, TypeScript, HTML, CSS, PHP, Python, Java, C, C++, C#, Go, Rust, SQL, JSON, XML, YAML, Markdown, and Bash with syntax highlighting powered by highlight.js.

How is the image generated?

The code is rendered in a preview area with syntax highlighting, then converted to a PNG image using html2canvas, which captures the HTML content as a canvas element and exports it as a high-resolution PNG.

Can I change the background color?

Yes, you can select from preset themes (dark, light, monokai, nord, github) that automatically set appropriate background and text colors, or choose a custom background for unique branding.

Is the code processing done locally?

Yes, all code processing, syntax highlighting, and image generation happen entirely in your browser. No code is uploaded to any server, ensuring your code remains private and secure.

What image format is used?

The tool generates PNG images with a transparent or solid background at 2x resolution for retina displays. PNG is the preferred format for code snippets as it preserves sharp text and colors without compression artifacts.
