Paste HTML or upload a file, then capture a beautiful screenshot for social media and docs.
Screenshots are rendered in your browser. Some CSS features may render differently than in a full browser. JavaScript execution is sandboxed for security.
About this tool
Render HTML into a beautiful screenshot, perfect for sharing code. Free, in-browser.
What Is the Code Screenshot?
The Code Screenshot is a free browser-based developer tool that handles HTML screenshot operations entirely on your device without any server round-trips. Built with standard web APIs and JavaScript, it processes your input locally — no code, data, or file content is ever uploaded to a remote server. The tool supports code screenshot standards and handles edge cases like Unicode characters, special encoding modes, and large inputs. Performance is optimized for files up to 10MB+ using streaming parsers where applicable. Unlike online alternatives that require accounts or impose usage limits, this tool is completely free with no caps.
Who Should Use This Tool?
Software developers use this tool daily for HTML screenshot tasks during coding, debugging, and deployment workflows. DevOps engineers rely on it for quick code screenshot conversions when configuring servers or CI/CD pipelines. QA testers validate website screenshot tool outputs against expected values. Students learning web development use it as a reference tool to understand how encoding and formatting actually work. Technical writers format code examples for documentation. The tool is especially valuable in secure environments where corporate policy prohibits pasting code into external websites — everything stays local.
How to Use the Code Screenshot
Paste or type your input into the text area — the tool processes it instantly with no submit button needed. For HTML screenshot operations, select your desired mode or options from the dropdown controls. The output panel shows results in real time with syntax highlighting where applicable. Use the copy button to transfer results to your clipboard. For batch operations, the tool handles multiple inputs separated by newlines. All processing happens in your browser's JavaScript engine — close the tab and your data is gone. Keyboard shortcuts (Ctrl+Enter) trigger the primary action for power users.
Frequently asked
What rendering engine does it use for HTML screenshots?
It renders your HTML and CSS using a headless browser engine, producing pixel-perfect screenshots at 1x or 2x resolution. Supported output: PNG (lossless) and JPEG (adjustable quality 1-100). Ideal for code snippet sharing, bug reports, and documentation—no need to open DevTools or install browser extensions.
Can I customize the screenshot dimensions and background?
Yes. Set custom viewport width (320px to 3840px), height, device pixel ratio, and background color (including transparent PNG). Add padding, rounded corners, and a macOS-style window frame for polished social media images. Export resolution up to 4K for print-quality documentation screenshots.
