Frequently Asked Questions
How does the HTML Viewer work? +
You paste your HTML code or upload an .html file. The tool uses your browser's rendering engine to display a live preview with formatted source. Everything stays on your device.
Is it really free? Are there limits? +
Yes, completely free. No limits on usage, no sign‑up, no hidden fees. Use it as much as you need.
Can I upload files other than .html? +
The tool is optimised for .html and .htm files. You can also copy and paste code from any source. For other text files, just copy the content.
Is my code stored or shared? +
No. All operations happen in your browser – no code is sent to any server. Once you close the page, everything is gone.
Does it support external CSS/JavaScript? +
Yes. The preview behaves like a regular browser – it will load external resources (like stylesheets or scripts) if they are linked correctly. For security, some third‑party resources may be blocked.
Can I test mobile responsiveness? +
Absolutely. You can resize the preview panel or choose preset device dimensions to see how your HTML renders on different screens.
