Minified production code and inconsistently-indented pasted snippets are both hard to read, for opposite reasons. One has no formatting left at all. The other has formatting that doesn't match your own conventions. This beautifies or minifies HTML, CSS and JavaScript with adjustable indentation, entirely client-side.
When you'd use this
Making sense of a minified vendor script or a compressed CSS file you need to read line by line, or cleaning up code copied from somewhere with inconsistent indentation before it goes into your own project.
Common errors
Beautifying code with a syntax error usually still produces some kind of output, though it may not reformat correctly around the broken section. If the formatted result looks wrong in one specific spot, fix the obvious syntax issue first and run it again.
Frequently asked questions
Does minifying change what the code does?
No. Minifying strips whitespace, comments, and other formatting that has no effect on execution. The logic is identical before and after; file size and readability are the only things that change.
