What is an HTML Viewer?

An HTML Viewer is a free online tool that lets you enter HTML code and instantly see the output in your browser. It works as a live preview, so you don’t need to save files or refresh the page manually.

This tool is very useful for web developers, students, and designers. You can quickly test code snippets, fix errors, and check how your design looks. It gives instant results, helping you find and solve problems faster.

Our HTML Viewer also comes with responsive previews, device testing options, and one-click execution, making your coding workflow faster and smoother.

Test on Multiple Devices

Always check your design on mobile, tablet, and desktop sizes using the device preview feature.

Validate Your Code

Use valid HTML to avoid browser issues. This makes your site more stable and reliable.

External Resources

External images, CSS, or scripts might not always load in the sandbox. Use inline code whenever possible.

Browser Testing

Our viewer shows results in your current browser. Still, always test in multiple browsers for accuracy.

Frequently Asked Questions

Yes, the HTML Viewer runs JavaScript code. However, for security, some advanced features may not work fully. Simple scripts will work without issues.
Yes, you can link external files. But sometimes, the browser’s security rules may block them. For best results, add CSS and JS directly in the code.
Since everything runs in your browser, the limit depends on your device power. Most devices can easily handle files of a few MBs, but very large files may run slowly.
Forms will show correctly but will not submit data because our viewer does not connect to any server. It is only for design and visual testing.
Right now, our tool does not save your projects. You can copy your code and save it in your editor. We may add a save option in the future.
The preview uses your browser’s engine, so it will look almost the same. But small changes may appear in other browsers or devices. Always test before publishing.
