From Terminal to Timeline: The Art of Code Screenshots

Sharing code on social media, documentation, or blog posts as plain text rarely captures attention. A beautifully rendered code image with syntax highlighting, editor chrome, and a curated color palette makes technical content visually engaging and instantly shareable. Code Prettier transforms raw snippets into polished images that stand out in any feed.

The tool runs entirely in your browser. Your code never touches a server. The syntax highlighting engine tokenizes your input using language-specific regular expressions, matching keywords, strings, comments, numbers, functions, and types against each theme's color palette. The result is rendered as styled HTML and captured at 2× resolution using the html2canvas library for crisp output on Retina and high-DPI displays.

Themes Inspired by Real Editors

Each of the 12 themes is handcrafted to match popular code editor aesthetics. Dracula, Monokai, Nord, and One Dark bring their iconic palettes directly into the image. Synthwave and Aurora add creative flair for visually striking social posts. Every theme defines colors for keywords, strings, comments, numbers, functions, types, operators, line numbers, and the window chrome dots.

Privacy-First Architecture

Unlike cloud-based code screenshot tools, Code Prettier never transmits your code. The entire pipeline — from syntax tokenization to canvas rendering — executes in the browser's JavaScript runtime. This makes it safe for proprietary code, internal APIs, environment variables, and any sensitive snippet you need to share visually without exposing the raw text to third-party servers.

Best Practices for Shareable Code Images

For maximum readability, keep code snippets under 25 lines. Use a font size of 14–16px for social media posts and 12–14px for documentation. macOS window chrome adds a familiar, polished feel, while "None" chrome gives a clean, minimal look for technical articles. Choose background gradients that contrast with the theme — dark themes pop against colorful backgrounds like Violet, Sunset, or Emerald.

The 2× resolution export ensures your code stays sharp after social media compression. Twitter, LinkedIn, and Instagram all re-encode uploaded images, but starting at double resolution preserves text clarity. For presentations and slides, use the Transparent background option and overlay the code image directly onto your slide design.
