Will minifying my HTML change how the page looks?

No. Minification only removes characters the browser ignores when rendering, such as indentation, line breaks between tags, and comments. The visible page is identical, because the tool preserves the meaningful spaces inside text and inside whitespace-sensitive elements like and .

How much smaller will my file get?

Typically 10 to 40 percent of the raw, uncompressed size, depending on how heavily formatted and commented your source is. If your server already uses gzip or Brotli, the net saving over the wire is smaller, because compression already shrinks repeated whitespace, but minify-then-compress is still the smallest result.

Does it remove Internet Explorer conditional comments like [if IE]?

Conditional comments such as are functional in old IE versions even though they look like comments. The minifier treats them carefully rather than stripping every comment indiscriminately, so legacy fallbacks are not silently removed.

Is it safe to minify HTML that contains inline CSS or JavaScript?

Yes. The tool leaves the contents of and blocks intact instead of crushing their line breaks, which avoids breaking JavaScript that depends on automatic semicolon insertion. For maximum savings, minify your CSS and JS separately with dedicated tools first.

Is my HTML uploaded anywhere?

No. All processing happens locally in your browser using JavaScript. Your markup is never sent to a server, logged, or stored, so it is safe to use with private or unreleased pages.
