Preformatted content stays intact
Minification removes comments and collapses whitespace-only nodes to one separator after parsing. It does not minify embedded CSS or JavaScript, and parser repairs can alter malformed source.
The parser runs locally with a 500 KiB input cap, 100,000-node and 100-level tree limits, and a 1 MiB output cap. It never fetches URLs, loads resources, uploads source, or saves a preset.
