Best Free Code Screenshot Tools
Plain-text code in social media posts and presentations looks dull and is hard to read. Code screenshot tools turn your snippets into beautiful, syntax-highlighted images that catch attention and display correctly everywhere. Here are the best free options.
tools.fun Code to Image
The tools.fun code-to-image tool converts code into a clean, syntax-highlighted image with customizable themes, padding, and language selection. Paste your code, pick a theme, adjust the window style, and download as PNG. The tool runs in the browser and supports dozens of programming languages.
The focus is on simplicity and speed. No account required, no watermarks, and the defaults produce good-looking images immediately. For quick code sharing on Twitter, LinkedIn, or Slack, it is the fastest path from code to image.
Carbon — The Original Code Image Tool
Carbon (carbon.now.sh) pioneered the code screenshot genre and remains the most popular option. It supports over 100 languages, dozens of themes (including VS Code themes), adjustable fonts, padding, line numbers, and window chrome styles. The images look polished out of the box.
Carbon also supports direct import from GitHub Gists — paste a Gist URL and the code loads automatically. The export options include PNG, SVG (for scalable images), and direct copy to clipboard. For presentation-quality code images, Carbon offers the most control.
Ray.so — Minimal and Beautiful
Ray.so (by Raycast) produces arguably the most aesthetically pleasing code images. The default gradient backgrounds are eye-catching, the window chrome is sleek, and the overall design feels premium. Customization is more limited than Carbon — fewer themes and no SVG export — but the defaults are so good that most people do not need to change anything.
Ray.so is the best choice when visual impact matters most — for blog hero images, slide decks, and social media content where the code image needs to look like part of a polished design, not just a screenshot.
Snappify — Advanced Features
Snappify goes beyond single code blocks to support multi-file views, animated code transitions (showing code evolution step by step), annotations with arrows and labels, and presentation mode for live coding demos. The free tier includes basic code images; the paid tier unlocks animations and advanced features.
For educational content — tutorials, course materials, blog posts explaining code — Snappify's annotation features save significant time compared to adding arrows and labels in a separate image editor.
Tips for Better Code Images
Choose the right theme: Dark themes (Dracula, One Dark, Night Owl) look better on dark social media backgrounds. Light themes (Solarized Light, GitHub Light) work better in documentation and blog posts.
Show only what matters: Remove import statements, boilerplate, and irrelevant code. The image should highlight the specific technique or pattern you are sharing.
Use comments: A brief comment at the top explaining what the code does makes the image self-contained. Viewers should understand it without reading your post's caption.
Mind the font size: Ensure the code is readable on mobile devices. Preview at 50% zoom before downloading — if you cannot read it at that size, increase the font or reduce the code length.
Alternatives to Code Images
For blog posts and documentation where the code should be copyable, use actual code blocks with syntax highlighting (Prism.js, Highlight.js, or your static site generator's built-in support). Code images are best for social media and presentations where copy-paste is not needed and visual impact matters most.
