Best Practice
Always minify your HTML as part of your build process rather than manually editing your source files.
Did You Know?
HTML minification can significantly improve Core Web Vitals, specifically Largest Contentful Paint (LCP).
HTML (HyperText Markup Language) is the standard language used to create the structure of web pages. It defines elements like headings, paragraphs, and links using a system of tags. While human-readable code is great for development, production environments benefit from minified HTML because browsers ignore the whitespace that developers use to make code readable.
Tip
Use the HTML Formatter to make minified code readable again if you lose your original source files.
html-minifier-terser during the build step.Q: Does minifying HTML break my website? A: No, a standard HTML minifier only removes whitespace and comments that do not affect the rendering of the DOM.
Q: Should I minify HTML during development? A: No, keep your source code readable during development and only minify during the build or deployment phase.
Q: How much size can I save? A: Depending on how many comments and spaces you use, you can typically see a reduction of 5% to 20% in file size.
Q: Can I still view the source code in the browser? A: Yes, browsers can still display minified source code, but it is much harder for humans to read without a formatter.

Removing HTML comments alone can sometimes reduce page size by several kilobytes on content-heavy sites.
