Frequently asked questions

What does HTML minification do?
Minification removes unnecessary characters without changing functionality: extra whitespace, comments, optional tags, default attributes, and redundant quotes. This reduces file size for faster page loads.
How much can minification save?
Typical savings are 10-30% of file size. Combined with gzip compression (which servers usually apply automatically), total transfer reduction can be 70-90%. Minification helps even with gzip because there\\
Is it safe to minify HTML?
Generally yes for display HTML. Be careful with: whitespace-sensitive elements (pre, textarea, script), inline SVG, and JavaScript that depends on DOM structure. Our minifier preserves content in sensitive areas.
Should I minify during development?
No, keep source HTML readable during development. Minify only for production deployment. Use build tools (Webpack, Gulp) to automatically minify during deployment, keeping source files clean and maintainable.
What about CSS and JavaScript inside HTML?
Inline CSS and JavaScript can also be minified. Our tool optionally minifies inline styles and scripts. For external files, use dedicated CSS/JavaScript minifiers which are more sophisticated for those languages.
