What is Online HTML Viewer?
It’s a free tool that lets you write, edit, and preview HTML and CSS right in your browser. No setup needed. Just start typing, and you’ll see your code update instantly.
Why We Made It
We were tired of flipping between code editors and browsers just to test a few lines of code. So we built something faster and simpler.
Whether you’re learning or just testing ideas, this tool gives you a clean, easy way to write and view HTML in one place.
What You Can Do
- Write & Edit: Code with syntax highlighting, auto-complete, and error checking.
- Live Preview: See changes instantly—no refresh needed.
- Import & Export: Open your own HTML files or download your work with a timestamp.
- Dark Mode: Easier on your eyes, especially at night.
- Responsive: Works well on any device. Resize panels and test layouts as you go.

How We Built It
We’re a small team of web devs who wanted a smoother way to test HTML online. So we focused on keeping it fast, stable, and easy—even with larger files.
