Beautiful Code Screenshots

Share your code on social media, documentation, or presentations with stunning visuals. This tool renders syntax-highlighted code inside a macOS-style window frame with customizable backgrounds — no screenshots of your IDE needed.

Why Use Code Images?

Code images get 5× more engagement on Twitter/X compared to plain text tweets. They preserve formatting across all platforms, look professional in presentations, and are perfect for tutorials and blog posts.

Code Themes and Customization

The Code Screenshot Generator supports 19+ programming languages including JavaScript, TypeScript, Python, Go, Rust, PHP, Java, C#, C++, Ruby, Swift, SQL, Bash, HTML, CSS, JSON, YAML, Markdown, and plain text. Each language is highlighted using Highlight.js with accurate tokenization for keywords, strings, comments, and functions — no manual formatting required.

Choose from six hand-picked themes: Atom One Dark, GitHub Dark, Monokai, Nord, Dracula, and GitHub Light. Each theme is paired with a matching macOS-style window frame color that adapts automatically — dark themes get dark title bars with a subtle border, while GitHub Light uses a clean white frame for a minimalist feel. The window frame includes traffic-light dots (red, yellow, green) and an editable filename display, giving every snippet a polished screenshot aesthetic that looks native to a code editor.

Beyond the frame, customize the surrounding space with 8 background gradient presets (Purple, Pink, Ocean, Mint, Sunset, Lavender, Dark, and Light) that sit behind the window. Adjust the padding from 16 px to 96 px to control the breathing room around your code, and set the font size between 10 px and 24 px for optimal readability at any display size. These controls let you tailor the output for Instagram stories, Twitter/X cards, slide decks, or documentation pages with minimal effort.

Export and Share Options

Once your code looks just right, you have multiple ways to save and distribute it. The Export PNG button renders the entire screenshot at 2× resolution via html2canvas and downloads a crisp PNG file — ideal for social media, slide decks, blog posts, or documentation. The Copy Image button places the screenshot directly onto your system clipboard as a PNG blob, letting you paste it instantly into Slack, Discord, Notion, Figma, or any image-aware application without saving a file first.

The Share Image button goes a step further by leveraging the Web Share API with a file attachment. On mobile devices (Android and iOS), it attaches the PNG file directly to the native share sheet so you can send it via WhatsApp, Telegram, email, or iMessage in one tap. On desktop, it copies the image to your clipboard and opens the browser's share dialog with a pre-populated link back to ByteBox, making it effortless to spread your snippet across the web while driving traffic to the tool.
