HTML Minifier
Minify, beautify, and compare HTML size
Overview
Minify or beautify HTML code. It also shows a file size comparison before and after compression so you can see the savings at a glance. Useful for optimizing HTML before production deployment or expanding minified HTML for debugging.
Key Features
- HTML minification (remove whitespace, comments, unnecessary attributes)
- HTML beautification (add indentation and line breaks)
- Before / after file size comparison (bytes, %)
- Inline CSS/JS minification option
- Copy and download results
How to Use
- Paste HTML code into the input field.
- Click Minify to compress or Beautify to format.
- Check the size comparison and copy the result.
Tips
- Removing comments alone can reduce file size noticeably, especially for CMS-generated HTML with many auto-comments.
- Minifying inline CSS/JS along with HTML further reduces the total file size.
- Beautify defaults to 2-space indentation. Use it for readable code reviews.
FAQ
- Can minification break the HTML?
- Standard HTML should not break from minification. However, intentional whitespace inside pre or code tags may display differently after compression.
- Does it handle server-side template code?
- Template tags from PHP, Jinja, EJS, etc. may produce unexpected results. It is recommended for pure HTML only.
- How much size reduction can I expect?
- It depends on the HTML structure and amount of comments/whitespace, but typically expect a 10-30% reduction. HTML with many comments or deep indentation benefits the most.
