Sharing a raw code snippet in a tweet or a slide looks flat. A styled screenshot with a window chrome and syntax coloring reads much better — this generates one entirely in your browser, no account or upload required.
What Is Code Screenshot?
Code Screenshot is one of the tools in WebdevToolbox’s Generators category — a Carbon.sh-style tool that renders your pasted code onto a styled canvas with a macOS-style title bar and downloads it as a PNG.
How to Use It
- Open the tool at /tools/code-screenshot.
- Paste your code snippet.
- Pick a theme (Dark, Light, Dracula, Ocean) and set a window title.
- Click “Download PNG” to save the image.
Key Features
- Four built-in themes — each with its own background, keyword, string, and comment colors.
- Auto-sized canvas — width and height scale to fit your code, so short snippets don’t get an oversized blank frame.
- Lightweight heuristic highlighting — comments, quoted strings, and common keywords are colored without needing a full language parser.
- Fully client-side rendering — the image is built on an HTML canvas; your code never leaves your browser.
When to Use Code Screenshot
- Sharing a snippet on social media or Slack in a more polished format than a plain code block.
- Adding a visual to a blog post or slide deck without a design tool.
- Highlighting a bug or a fix in a bug report or PR comment.
