HTML formatters (beautifiers) add proper indentation and structure to make code readable. This is essential when debugging, reviewing, or learning from HTML code.
HTML minifiers do the opposite - they remove all unnecessary whitespace to reduce file size. This is common for production websites where every kilobyte affects load times.

What is HTML formatting?
HTML formatting (also called beautifying) adds proper indentation and line breaks to make the code readable. It helps developers understand the structure of HTML documents, especially when working with generated or minified code.
What is HTML minification?
HTML minification removes unnecessary whitespace, comments, and line breaks to reduce file size. This improves page load times but makes the code unreadable for humans.
Should I use 2 or 4 space indentation?
Both are valid. 2 spaces is more compact and common in web projects (used by Google, jQuery). 4 spaces is more readable and common in Python-influenced codebases. Choose based on your project's conventions.
Does minifying break the HTML?
Proper minification doesn't break HTML - it only removes whitespace that browsers ignore. However, some inline scripts with string literals may be affected, which is why we offer an option to preserve comments.
