HTML Minifier

Minify HTML by removing comments and unnecessary whitespace while preserving valid markup.

About HTML Minifier

HTML Minifier helps you shrink HTML markup for production, embeds, and templates without changing the page structure. It removes regular comments, collapses excessive whitespace in text nodes, and strips line breaks between tags for compact output. Conditional comments are preserved so compatibility blocks stay intact.

Why use HTML Minifier

  • Reduce HTML payload size for faster pages and smaller snippets.
  • Keep output compact while preserving structural validity.
  • Control case handling for stricter template conventions.

How to use HTML Minifier

  1. Paste HTML into the input panel.
  2. Toggle comment removal, whitespace collapse, and preserve-case options.
  3. Click Minify and review output size.
  4. Copy or clear output as needed.

When to use HTML Minifier

  • Before publishing static or server-rendered HTML.
  • When embedding HTML in scripts, JSON, or templates.
  • When cleaning editor-exported markup quickly.
