An online HTML viewer is a browser-based tool that turns raw HTML code into a rendered web page. You paste your markup or upload an .html file, and the viewer displays the result as a real browser would — including the CSS and JavaScript inside your code. There is no code editor to set up and nothing to install.
You preview HTML online in three steps: add your code, generate the preview, and share the link. Paste your HTML into the input box or use the Upload HTML file tab to load a document from your computer, then select Generate preview link. The viewer renders your page and gives you a live URL.
A shareable preview link is a standalone URL that displays your rendered HTML page. Instead of sending raw markup that teammates or clients have to open in their own editor, you send one link that shows the finished design in any browser. Anyone with the link views the rendered result directly — no file download and no software required.
Paste the HTML an AI tool produced and generate a shareable preview link. Tools like Claude and ChatGPT output complete HTML for a design, but a client cannot judge raw code. The viewer renders that output into a live page and gives you one URL to send, so the recipient sees the finished design in their browser instead of the markup.
This works with HTML from any AI tool. Copy the generated code, paste it into the input box or upload the exported .html file, and select Generate preview link. The link shows the rendered result exactly as a browser displays it — useful for sending AI-built mockups, landing pages, or email layouts to teammates and clients for review.
An HTML viewer is faster than a code editor when you only need to see and share a result. Editors like VS Code are built for full projects with folder management and version control, which is more than you need to check one block of markup. An online HTML viewer works as a blank slate: drop in your code, generate a preview, and share it on any device.
Developers, designers, and students use an HTML viewer to preview and share markup without a development environment. The most common tasks are reviewing designs, sharing previews with a team, and checking how a snippet renders.
.html file and view the rendered page without installing anything.No. Modern browsers render a stray <div> or <button> on its own, so a fragment previews fine for a quick check. Include the full document structure — <!DOCTYPE html>, <head>, and <body> — when you need to test meta tags or page-level CSS that depends on the document head.
