What is an HTML viewer and why do I need one?

An HTML viewer lets you preview HTML files as rendered web pages or view the source code without needing a web server or code editor. It's useful for checking saved web pages, previewing email templates, reviewing HTML exports from applications, or inspecting HTML attachments safely - all without installing any software.

Is my HTML file kept private when viewing online?

Absolutely! DocsYogi processes your HTML file entirely in your web browser using JavaScript. Your file is never uploaded to any server - it stays on your device at all times. The HTML is rendered in a sandboxed iframe that's completely isolated from the rest of the browser.

Will JavaScript in my HTML file execute?

No. For security, JavaScript is blocked from executing in the sandboxed preview. This protects you from potentially malicious scripts in untrusted HTML files. If you need to test JavaScript, use a local development environment or browser developer tools.

Why don't images or stylesheets load in my HTML file?

If your HTML references external resources using relative paths (like src='images/logo.png'), those files aren't available since only your HTML file is loaded. Images embedded as data URIs (base64) will display. For full functionality with external resources, open the HTML file directly in your browser or use a local web server.

Can I edit HTML files with this viewer?

DocsYogi is a read-only viewer designed for previewing HTML files. For editing, use a code editor like VS Code, Sublime Text, or online editors like CodePen or JSFiddle. You can copy the source code from DocsYogi's source view and paste it into your preferred editor.

What's the difference between viewing HTML and opening it in a browser?

Opening directly in a browser executes all scripts and loads external resources, which can be a security risk for untrusted files. DocsYogi provides a safe, sandboxed preview that blocks scripts and clearly separates the rendered view from source code view - helpful for inspection without execution.

Can I view HTML emails with this viewer?

Yes! HTML emails are regular HTML files. You can preview how an email template looks (rendered view) or examine the underlying code (source view). Note that images using external URLs may not load if the original server blocks cross-origin requests.

How large can my HTML file be?

You can view HTML files up to 50MB. Most HTML files are much smaller (typically under 1MB). Very large HTML files with many embedded images (as data URIs) or extensive content may take longer to parse and render depending on your device's capabilities.
