Minified production code and inconsistently-indented pasted snippets are both hard to read for different 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 actually read, 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, but it may not reformat correctly around the broken section - worth fixing an obvious syntax issue first if the formatted result looks wrong in one specific spot.
Frequently asked questions
Does minifying change what the code actually does?
No - minifying only removes whitespace, comments, and other formatting that doesn't affect execution. The logic is identical before and after; only the file size and readability change.
