- The contents of pre, textarea, script and style are processed by HTML minifier on an element-by-element semantic basis.

HTML Minifier Features
Securely compress documents using a proven HTML minifier and protect pre-formatting and inline whitespace semantics. It is suitable for daily development, debugging, data sorting and code optimization scenarios. The processing results can be directly viewed, copied or downloaded.
FAQ
Why can't you just remove all whitespace?
Whitespace between inline elements affects visible text, and pre/textareas are also left blank; global replacement breaks content.
Will the code in script and style be compressed?
The current configuration does not additionally minify inline JS/CSS and just lets the HTML minifier safely handle element boundaries.
Can the compression result directly replace the source code?
Mature tools reduce risks, but complex template syntax may have special constraints; the source code should still be retained and project tests should be run before deployment.
