Carbon Code Snippet Image Generator

Carbon is a free online tool for creating and sharing beautiful images of source code, widely used by developers, technical writers, and conference speakers to generate visually appealing code snippets for presentations, blog posts, social media, and documentation. Created by Mike Fix and maintained as an open-source project with over 35,000 GitHub stars, the tool provides a real-time editor where users paste their code and instantly see a rendered preview with syntax highlighting applied through the Prism.js library supporting over 200 programming languages. The customization options include over 50 themes inspired by popular editor color schemes such as Seti, Monokai, Dracula, Night Owl, Solarized, One Dark, and GitHub Light, adjustable window controls including the macOS-style traffic light buttons, customizable background colors and gradient patterns with optional noise texture, configurable padding and margins, drop shadows with adjustable blur and opacity, and font selection from popular programming fonts including Fira Code, JetBrains Mono, Hack, IBM Plex Mono, and Source Code Pro. Export formats include high-resolution PNG suitable for retina displays and print, SVG for scalable web embedding, and direct Twitter posting integration. Advanced features include language auto-detection from pasted code, line number toggling, adjustable line height and font size, window title customization, multi-line selection highlighting, and the ability to save and share snippets via unique URLs. The tool is hosted on Vercel and requires no account for basic usage, with optional GitHub authentication for saving and organizing snippets. Sponsorship from companies like Auth0 and Vercel keeps the service free for the developer community.
