Questions
Is it safe for every page?
Whitespace is collapsed, not removed between inline elements, and <pre>/<textarea> content is untouched, so rendering stays the same.
Should I minify by hand?
For a one-off page, yes. For a website, build tools or server compression (gzip/brotli) usually save more automatically.
Are comments removed?
Yes, except conditional comments and ones starting with “!”. You can keep all comments with the option.
