Does HTML minification affect SEO or Google rankings?

Positively! Minified HTML reduces Time to First Byte (TTFB) and Total Blocking Time (TBT), which are key signals in Google PageSpeed and Core Web Vitals metrics.

Is any confidential markup or web page content uploaded?

No. All whitespace compression and AST cleanup take place exclusively inside your browser sandbox with zero external server queries.
