Welcome to the HTML Viewer! Paste your HTML code below and see how it renders instantly. It's a quick and easy way to test and preview your HTML output.
Why Use an Online HTML Viewer
Testing a snippet of HTML — a widget embed, a piece of markup from a tutorial, or code you're unsure about — usually means saving a file and opening it in a browser just to see the result. This tool skips that step entirely: paste your code, click the button, and see the rendered output immediately, right on this page.
- Testing embed codes: check that a third-party widget, tracking script, or iframe renders correctly before adding it to your site.
- Debugging markup: spot a broken layout or unclosed tag by seeing the visual result instantly.
- Learning HTML: experiment with tags and see exactly how each change affects the output.
- Extracting visual text: use "Copy Visual Text" to grab the rendered content with all HTML attributes stripped out — handy when you want just the plain structure, not the styling.
How to Use the HTML Viewer
Paste your HTML into the box above and click "Tampilkan HTML" to render it in the preview panel below. If your code includes inline CSS or JavaScript, both run as part of the live preview. Click "Copy Visual Text" to copy the rendered output with attributes removed, ready to paste elsewhere as clean markup.
Built with a Safety Sandbox
Since this tool renders whatever code you paste — including any JavaScript inside it — the preview runs inside a sandboxed iframe. This is the same safety practice used by established code-preview tools: scripts in the pasted code can still run so interactive widgets work, but the preview is isolated from the rest of the page, so a pasted snippet can't reach outside its own preview box.
Frequently Asked Questions
Can I preview HTML with embedded CSS and JavaScript?
Yes. Both inline styles and scripts inside your pasted code run as part of the live preview, so a complete single-file page renders the way it would in a real browser.
Is it safe to paste code I got from somewhere I don't fully trust?
The preview runs in a sandboxed iframe, which isolates it from the rest of the page. That said, treat any code from an unknown source with the same caution you would anywhere else online — sandboxing limits what the preview can reach, but it isn't a reason to paste something you wouldn't otherwise run.
What does "Copy Visual Text" actually copy?
It copies the rendered content from the preview with all HTML attributes (classes, styles, ids, etc.) stripped out — useful when you want the plain structural markup without the original styling.
Is my code uploaded or saved anywhere?
No. Everything — the rendering and the copy function — runs directly in your browser. Nothing you paste is sent to a server or stored after you leave the page.
Does this replace testing on a real staging site before going live?
Not entirely. It's excellent for quick checks of markup and layout, but final testing on an actual staging environment is still worthwhile for anything going to production, especially for scripts that depend on your site's specific environment.
