Question 1

How does the View Any File HTML Viewer & Renderer work?

Accepted Answer

This tool allows you to upload an .html or .htm file. The content of the file is then rendered inside a sandboxed `iframe` directly in your browser, allowing you to see how the HTML page looks.

Question 2

Is it safe to view HTML files with this tool?

Accepted Answer

Yes, the HTML content is rendered within a sandboxed `iframe`. This helps to prevent potentially malicious scripts within the HTML from affecting the main page or accessing sensitive information. However, always be cautious with files from untrusted sources.

Question 3

Can I view HTML files with external CSS or JavaScript?

Accepted Answer

The HTML viewer primarily focuses on rendering the HTML structure and inline styles/scripts. External resources like CSS files, JavaScript files, or images linked with relative paths within the HTML might not load or function correctly, as the HTML is rendered in isolation. For full project testing, use a local development server.

Question 4

Does this viewer execute JavaScript in the HTML file?

Accepted Answer

The `iframe` is sandboxed with `allow-scripts`, so JavaScript within the uploaded HTML file will be allowed to run within the confines of that iframe. Be aware of this if opening HTML files from untrusted sources.

Question 5

What are .htm files?

Accepted Answer

.htm is simply an older, shorter version of the .html file extension. They are functionally the same, and this viewer supports both.
