Frequently asked questions
Does it minify HTML too?
This tool focuses on beautifying. For minification, use a dedicated HTML minifier.
Will it break my templates?
It preserves template syntax like {{ }} and <% %> as plain text inside tags.
Is my HTML uploaded?
No — formatting runs entirely in your browser.
Can I configure indentation?
Yes — choose between 2-space and 4-space indenting.
Does it validate HTML?
Validation is separate from formatting; this tool only beautifies. Use a validator for syntax checking.
