HTML Minifier & Beautifier
HTML minification removes whitespace between tags, line breaks, and comments (except IE conditional comments) to reduce file size by 10-25%. Preserves content in <pre>, <textarea>, <script>, and <style> tags. For example, "<div> <p>Text</p> </div>" becomes "<div><p>Text</p></div>". Use htmlnano, html-minifier-terser, or build tools (Webpack, Vite). Combined with gzip compression, achieves 60-75% total size reduction. Always keep source HTML for development; minified HTML is for production deployment only.
Minify HTML to reduce file size or beautify/format HTML with proper indentation. Remove comments, whitespace while preserving pre, textarea, script, and style content. Real-time processing with syntax highlighting.

Frequently Asked Questions
- What does HTML minification do?
- HTML minification removes unnecessary characters from HTML code without changing how the page displays or functions. This includes removing whitespace between tags, line breaks, HTML comments (except conditional comments like <!--[if IE]-->), and collapsing multiple spaces within text. Content inside <pre>, <textarea>, <script>, and <style> tags is preserved to maintain functionality. Minified HTML files are smaller and load faster.
- Does minifying HTML affect how my webpage looks?
- No, HTML minification does not change how your webpage looks or behaves. The minifier removes only whitespace and comments that browsers ignore during rendering. All HTML tags, attributes, text content, and functionality remain identical. Special tags like <pre> and <textarea> that require whitespace preservation are handled correctly.
- How much can HTML minification reduce file size?
- HTML minification typically saves 5-20% of file size depending on the original formatting and comment density. Well-indented HTML with many comments sees the largest savings. For a 100 KB HTML file, minification might save 5-20 KB. Combined with server-side gzip compression, total file size reduction can reach 70-80%. The bandwidth savings add up across millions of page views.
- Should I minify HTML for production websites?
- Yes, minifying HTML is a standard optimization for production websites. Smaller HTML files mean faster page load times, lower bandwidth costs, and better user experience, especially on slow connections. Modern build tools (Webpack, Vite, Gulp) often include HTML minification in their production builds. Always keep the original formatted HTML source files for development and debugging.
- What is the difference between minify and beautify HTML?
- Minify removes all unnecessary whitespace, line breaks, and comments to create the smallest possible HTML file for production. Beautify (also called formatting or prettifying) adds proper indentation, line breaks, and spacing to make HTML human-readable for development. Both operations preserve the functional structure and rendering of the HTML.
- Can I recover comments from minified HTML?
- No, HTML comments are permanently removed during minification and cannot be recovered. This is why you should always keep your original source HTML files with comments intact for documentation and future edits. Only use the minified HTML for deployment to production servers.
