Frequently Asked Questions

Is HTML cleaning safe for my website?

Yes, HTML cleaning is completely safe when using the right options. It only removes unnecessary elements like comments and whitespace without altering the actual content or structure of your HTML. Always keep a backup of your original code for reference.

How much can I reduce my HTML file size?

Typical savings range from 15% to 40% of the original file size, depending on how much formatting and comments your HTML contains. Well-commented and properly formatted HTML will see the highest compression ratios. Some highly optimized sites might see smaller gains.

Can I clean multiple HTML files at once?

Currently, the tool processes one file at a time. However, you can use the file upload feature to quickly load and clean individual HTML files. For batch processing, we recommend using our API or command-line version for enterprise users.

Will cleaning HTML affect my CSS and JavaScript?

No, the HTML cleaner preserves all functional code including CSS and JavaScript. When you enable minification options, it only removes whitespace and comments from inline scripts and styles, which doesn't affect functionality but reduces file size.

Is my data secure when using this tool?

Yes! All processing happens locally in your browser. Your HTML code is never uploaded to any server, ensuring complete privacy and security for your sensitive data. You can even use this tool offline after the initial page load.
