About HTML Minifier & Beautifier
Minify HTML by removing unnecessary whitespace between tags, stripping HTML comments, and collapsing multiple spaces. Or beautify minified HTML with proper indentation for readability. Shows file size before and after. Useful for optimizing HTML email templates, static pages, and server-rendered HTML before delivery. All processing is client-side.
All processing happens entirely in your browser using modern web APIs. Nothing is uploaded to our servers — your data stays local and private. Free to use forever.
Common use cases
- Minifying HTML templates for slightly faster page delivery
- Beautifying minified HTML from a build output for debugging
- Stripping comments from HTML before publishing
- Formatting HTML email templates for readability during development
- Cleaning up copy-pasted HTML with inconsistent indentation
How it works
Minification uses regex-based processing: collapses whitespace between > and < to a single space (or removes it entirely for block elements), strips HTML comments (<!-- ... -->) except conditional comments (<!--[if IE]>), and collapses multiple spaces within attributes. Beautification uses a tag-by-tag parsing approach that adds indentation based on nesting depth.
