HTML Formatter and Beautifier

What this tool does

undefined

How it works

Formatting re-indents HTML with your chosen indent size for readability; minifying strips it down to the smallest valid form. Both run entirely client-side - nothing is uploaded.

Frequently asked questions

Does formatting validate my HTML?
Formatting will surface a readable error if the input cannot be parsed, so a successful format is a good sign your syntax is valid.

Is this the same as the existing HTML Minify tool?
No - the existing minifier only compacts code. This tool adds beautify/pretty-print (with adjustable indentation) as well as minify, for the opposite direction.
