About Github Html Preview
Want to see how an HTML file on GitHub actually renders — instead of the raw code?
Github Html Preview shows you a safe preview in one click, without downloading the file or pasting your code into some online renderer.
🔐 Safe, and instant
• HTML renders inside an isolated sandbox — kept separate from the GitHub page you're viewing and your logged-in session
• Zero server, zero login, zero data collection — everything happens inside your browser
• Your code is never uploaded anywhere (unlike third-party online preview sites)
• Only activates on github.com and raw.githubusercontent.com
✅ Key Features
• Injects an [HTML Preview] button right next to GitHub's Raw button on any .html page
• One click renders the HTML in a new tab
• Paste any HTML snippet into the popup for an instant preview
• Handles GitHub's SPA navigation: keeps working after clicking between files
