Frequently Asked Questions
What is Aggressive Mode?
Aggressive Mode goes a step further by removing spaces around HTML attributes (e.g., class="box" becomes class=box where safe) to squeeze out every last byte. Use it carefully and always test your layout.
Will minification affect my design?
No. Standard HTML minification only removes unnecessary structural whitespace. Your website will look exactly the same but load much faster.
Is my code uploaded to your servers?
Absolutely not. The entire minification and SEO analysis process runs locally inside your browser using JavaScript. It is 100% private and secure.
