Did You Know?
HTML minification can reduce document weight by 10-20% depending on the amount of comments and spacing.
Best Practice
Always use a minifier as a build step rather than writing minified code manually to maintain developer productivity.
HTML (HyperText Markup Language) is the standard markup language for documents designed to be displayed in a web browser. It defines the structure and content of web pages using a series of elements and tags. While developers use indentation and comments to make HTML readable, these elements are ignored by browsers during rendering. Minification removes this human-centric formatting to create a compact file that is more efficient for servers to transmit and browsers to parse.
Tip
Combine HTML minification with Gzip or Brotli compression at the server level for the best possible load times.

A: No, minification only removes unnecessary characters like extra whitespace and comments. It does not alter the actual rendering or layout of your page.
Q: Should I minify my source files? A: No, you should always keep your original, formatted HTML for development. Only the files served to users in production should be minified.
Q: Can I minify inline CSS and JavaScript?
A: Many advanced minifiers, including the one used here, can be configured to also compress code inside <style> and <script> tags.
Q: Is it safe to remove HTML comments? A: Generally yes, unless you are using specific server-side directives or IE conditional comments that are still required for your environment.
