Cleaning up markup scraped from another website, or shrinking a page's HTML before deployment, are two very different needs served by the same tool. This formatter prettifies HTML with consistent, configurable indentation for readability, or minifies it into a single compact block to reduce file size, giving developers a quick way to tidy or compress markup without a full build pipeline.

No, formatting only adjusts whitespace and indentation in the source code, it does not alter the DOM structure or how the page looks when rendered.

Minification typically strips unnecessary whitespace and can remove comments, which shrinks file size but also removes any inline notes for other developers.

Basic indentation is applied around these blocks, but the JavaScript or CSS content itself is not deeply reformatted, use the dedicated JS or CSS formatter for that.

No, it focuses on formatting rather than checking for invalid or deprecated HTML, use a dedicated validator if you need standards compliance checking.

Pro tips
  • ·Formatting only touches whitespace and indentation, it will not fix invalid or deprecated markup, so pair it with a validator if standards compliance matters.
  • ·Use the dedicated JS or CSS formatter for the contents of <script> and <style> blocks, this tool only lightly indents around them.
  • ·Minifying strips comments along with whitespace, so keep an unminified copy if you rely on inline notes for other developers.
