Is my HTML code safe?

Yes. All formatting happens entirely in your browser. Your code is never sent to any server.

What does 'Minify' do to my HTML?

Minification removes unnecessary whitespace, newlines, and comments to reduce file size.

Does it support HTML5?

Yes, the js-beautify library fully supports HTML5 tags, attributes, and custom elements.

What is the maximum file size I can format?

No hard limit, but very large files (over 5MB) may be slow depending on your device.

Can it format embedded CSS and JavaScript?

Yes! js-beautify automatically formats CSS in <style> tags and JavaScript in <script> tags.
