HTML Minifier & Prettifier

HTML minification removes unnecessary whitespace, comments, and redundant code from HTML files to reduce file size. This improves website loading speed, reduces bandwidth usage, and enhances user experience, especially on mobile devices and slow connections.

Minifying removes all unnecessary whitespace and formatting to create the smallest possible file size. Prettifying adds proper indentation, line breaks, and spacing to make HTML code readable and easier to debug or maintain.

No, minifying HTML only removes whitespace and formatting that browsers ignore. The visual appearance and functionality of your website remains exactly the same, but the file loads faster due to reduced size.

Minification removes unnecessary whitespace, line breaks, tab characters, comments, and redundant spaces between attributes. It preserves all essential HTML structure, content, and functionality while reducing file size.

Yes, this tool can handle HTML files with inline CSS and JavaScript. However, for optimal results, consider using specialized CSS and JavaScript minifiers for those sections, as they can provide more aggressive optimization.

Yes, all processing happens entirely in your browser using client-side JavaScript. No HTML content is sent to servers, so your code remains completely private and secure throughout the minification or prettification process.

File size reduction varies depending on the original HTML structure. Typically, you can expect 10-30% reduction in file size. HTML with lots of whitespace and comments will see greater reduction than already compact code.

Yes, the tool can handle large HTML files, but very large files (several MB) might take a moment to process and may affect browser performance. For extremely large files, consider using command-line tools or build process integration.

No, prettifying only formats existing HTML with proper indentation and spacing. It doesn't fix syntax errors, missing tags, or invalid HTML structure. The tool will format your HTML as-is, preserving any existing issues.

You can choose between 2 or 4 spaces for indentation when prettifying HTML. The choice depends on your coding standards or team preferences. Most web development teams use either 2 or 4 spaces consistently.

Once HTML is minified, you cannot perfectly restore the original formatting since whitespace information is lost. However, you can use the prettify feature to add readable formatting to minified HTML, though it won't match the original structure exactly.

Yes, minifying HTML for production is a web performance best practice. It reduces load times and bandwidth usage. Keep unminified versions for development and debugging, and use minified versions for live websites.
