About JSON Minifier
Minifying JSON removes the whitespace that only exists to make it readable - indentation, line breaks and the spaces after colons and commas. The data is identical; it is the same object parsed the same way, just smaller on the wire.
The saving is worth having on anything you ship: API responses, config bundled into a page, JSON embedded in HTML. On heavily indented files it commonly cuts 20-30% of the bytes before compression even starts.
