Frequently Asked Questions
What is HTML minification?
HTML minification is the process of removing unnecessary characters (whitespace, comments, line breaks) from HTML code without changing its functionality. This reduces file size and improves page load times.
What is HTML beautification?
HTML beautification (or formatting) adds proper indentation, line breaks, and spacing to HTML code to make it more readable and easier to maintain.
Should I remove comments when minifying?
For production websites, yes - removing comments reduces file size. However, keep comments if you need them for documentation or if they contain important information like license notices.
How much can I reduce file size?
Typical HTML minification can reduce file size by 10-30%, depending on how much whitespace and comments are in the original code. The tool shows exact reduction percentage.
Is my HTML code secure?
Yes! All processing happens entirely in your browser. Your HTML code is never sent to any server and never leaves your device.
Can I use this for production websites?
While this tool is great for quick minification, for production websites we recommend using build tools like webpack, gulp, or grunt that integrate minification into your deployment process.
