Questions
Does JavaScript or PHP minify actually produce tiny, single-line output?
No, deliberately. Minify here is conservative: it strips comments and collapses blank lines and indentation, but never joins statements onto one line. A real single-line minifier for JavaScript has to reason about automatic-semicolon-insertion hazards to stay correct, which a hand-written tokenizer without a full parser cannot safely guarantee - so this tool trades maximum compactness for a guarantee that it never changes what your code does.
Will formatting HTML break a <script> or <style> block inside the page?
No. Content inside <script>, <style>, <pre> and <textarea> elements is treated as opaque and copied through untouched - only the surrounding tags are indented. Reformatting code or preformatted whitespace inside those elements would risk corrupting it.
Is my code ever executed to format it?
Never, for any of the seven languages. Every formatter here is a pure text transform built on a hand-written tokenizer that recognises strings, comments and language-specific quoting well enough to move whitespace around safely - nothing is parsed into a runnable form, evaluated, or sent anywhere.
