Overview

Add Preview buttons to HTML code blocks and render the chosen block in a new tab.

HTML One-click Preview removes the repetitive copy-paste step when reviewing HTML shared in chats, documentation, and web-based tools. Click the extension icon on a page to add a Preview button to each detected HTML code block. Choose the exact block you want, and the extension renders it in a full-size new tab. If you select HTML text or focus an editor containing HTML first, the extension previews that content directly. Features: - Detects HTML code blocks without choosing one for you. - Adds an independent Preview button to every matching block. - Supports selected HTML, focused editors, HTML fragments, and complete documents. - Resolves relative styles, scripts, images, and links from the source page URL. - Uses temporary session storage and removes preview data after it is opened. - Runs previewed JavaScript in a manifest-declared sandbox without access to extension APIs or the source tab. - Requests access only after you click the toolbar icon. It does not request permanent access to every website. All HTML detection and preview preparation happen locally in your browser. The extension does not operate a server, collect analytics, sell data, or transmit browsing activity to the developer. Previewed HTML can make its own network requests, just as it would in a normal web page. Only preview code you trust.
