FAQ
What does HTML minification do?
Removes unnecessary whitespace, comments, and optional tags to reduce file size without changing functionality.
Does it break my HTML?
No. Only safe removals: extra whitespace, comments, optional closing tags. Structure and functionality are preserved.
How much size reduction?
Typically 10-30% depending on formatting and comments in the original.
Is my code uploaded?
No. All processing in your browser.
Does it remove comments?
Yes. HTML comments (<!-- -->) are removed. Conditional comments for IE are preserved.
Does it handle inline CSS and JS?
Inline styles and scripts are preserved but whitespace within them is also compressed.
Can I upload a file?
Yes. Upload .html files directly.
Can I download the result?
Yes. Download as .html file.
Does it work with templates?
Yes. Template syntax (JSX, Handlebars, etc.) is treated as text and preserved.
Is there a size limit?
No practical limit.
Does it work on mobile?
Yes.
Can I beautify instead?
This tool minifies. For formatting, paste into a code editor with auto-format.
Does it affect SEO?
No. Minification does not change content visible to search engines.
