How it works
How to use the HTML Pretty Print
Paste HTML
A full page or a fragment.
Choose indentation
And line wrapping or attribute layout.
Copy the result
Or switch to Minify.
What gets formatted
Tags are indented by nesting depth, long lines are wrapped, and inline <style> and <script> blocks are formatted too. Whitespace-sensitive elements stay untouched.
Built for developers
Why developers use it
Private by design
Runs 100% in your browser. Nothing you paste is uploaded, logged or stored on a server.
Instant results
Output updates as you type, with precise error locations when something is wrong.
Works offline
Once loaded, the tool keeps working without a connection. Install it as an app if you like.
Free, no sign-up
No accounts, no limits, no watermarks.
FAQ
Frequently asked questions
Will my page look different?
Almost never — only whitespace between tags changes.
Is my data uploaded anywhere?
No. Everything runs locally in your browser — nothing you paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
