About this tool
This is a lightweight tag indenter, not a full HTML parser. It helps with nested markup you already trust.
How it works
Paste HTML, format, and copy. Self-closing tags such as br and img do not increase indent.
indent by opening/closing tags
Examples
Nested divs
Each inner tag is indented two spaces.
FAQ
Will this fix invalid HTML?
No. It only rearranges whitespace around tags.
Is my data uploaded?
No. Formatting, encoding, and generation run in your browser.
Can I use this offline after the page loads?
Yes, as long as the page stays open. Nothing is sent to a SmartKitio API.
