Is minifying HTML the same as Gzip compression?
No. Minification removes human-readable characters permanently; Gzip is a separate server-side compression layer applied during transfer. They're complementary — use both.

FAQ
Does minifying break my page's functionality or layout?
Not normally — this strips comments and collapses whitespace between tags only, without touching structure or content. Frameworks with whitespace-sensitive rendering are the one edge case worth spot-checking.
How much smaller does my HTML actually get?
Depends on how much whitespace and commenting the original has — often 10-30%. Combined with Gzip on your server, total savings can reach 70-90%.
Should I keep an unminified copy?
Yes — keep your readable source for editing, and minify only the deployed output.
Does minification help SEO or page speed scores?
Indirectly — smaller files load faster, which contributes positively to Core Web Vitals and page speed signals.
Is my HTML uploaded to a server?
No — minification runs entirely in your browser.
