HTML Minifier

HTML exported from a page builder or written by hand often carries extra indentation, blank lines, and comments left over from development — none of which a browser needs to render the page correctly. This tool strips that out, reducing the file size of your HTML without changing how it displays.

What this minifier removes

HTML comments (the <!-- ... --> notes developers leave in the markup) are removed entirely. Whitespace between tags — the line breaks and indentation used to make nested HTML readable — is collapsed down to the minimum needed. The visible text content and all actual HTML tags, attributes, and their values are left completely untouched, since only the human-readability formatting is being stripped, not the content itself.

When this is worth doing

Reducing the file size of a static HTML page before uploading it to a server with limited bandwidth or storage. Preparing HTML email templates, where smaller file size can help avoid triggering spam filters that flag unusually large emails. Cleaning up HTML exported from a design tool or page builder that tends to add generous whitespace and auto-generated comments.

Frequently Asked Questions

Will minifying affect how the page looks or works? For well-formed HTML, no — removing whitespace between tags and comments doesn't change the rendered output, since browsers already collapse most whitespace when displaying a page; however, it's worth checking the result if your HTML relies on whitespace-sensitive elements like <pre> tags.

Does this minify inline CSS or JavaScript inside the HTML? No — this tool only processes the HTML structure itself; for CSS or JS embedded in <style> or <script> tags, use the CSS Minifier tool separately on that portion if needed.

Is my HTML code uploaded anywhere? No — minification happens entirely in your browser using JavaScript; nothing is sent to a server.
