How to use this text tool

  • Paste HTML into the input box.
  • Choose safe or aggressive mode.
  • Decide whether comments should be removed.
  • Run the minifier and copy or download the compressed HTML.

What this tool does

This HTML minifier reduces markup size for production pages while showing saved bytes, compression percentage, tag counts, and safe-minification notes.

Processing logic: protect pre, textarea, script, and style blocks; remove optional comments; collapse whitespace between tags; and calculate reduction metrics.

Aggressive minification may affect whitespace-sensitive layouts. Use safe mode unless you know the markup is not whitespace-sensitive.

Example

Try the sample input, run minify html, and compare the before-and-after structure in the result panel.

Use cases

  • Clean code before review or sharing.
  • Prepare structured text for documentation, snippets, or production workflows.
  • Check size, line count, structure, and quality before exporting.

Tips for better output

  • Minify CSS and JavaScript separately for better control.
  • Do not remove conditional comments if supporting legacy environments.
  • Keep source HTML formatted for maintenance.

FAQ

Does HTML minification improve page speed?

HTML minification can reduce transfer size, which may improve load time slightly, especially on large pages.

Can HTML comments be removed safely?

Most comments are safe to remove, but conditional comments, template comments, or build markers may need to stay.

Will browsers read compressed HTML correctly?

Browsers can read minified HTML because HTML generally ignores unnecessary whitespace between tags.

How much space can HTML minification save?

Savings vary, but pages with many comments, indentation, and blank lines usually compress more than compact pages.

Is HTML minification reversible?

A formatter can make minified HTML readable again, but removed comments and original spacing choices cannot be restored.
