HTML / CSS Beautifier
Re-indent messy HTML or CSS markup for quick readability, locally.
Private by design. Every tool runs 100% in your browser — your code, text, and tokens never leave your device. Nothing is uploaded or stored.
Basic tag/brace indentation for quick readability. It does not validate; for strict formatting use a dedicated HTML/CSS formatter in your build.

Frequently Asked Questions
Will re-indenting break my markup?
No. Whitespace between block elements rarely changes rendering, and the beautifier preserves significant inline whitespace. The result is the same DOM, just readable.
Why indent CSS at all?
Readable CSS makes cascade and specificity bugs easier to spot. The beautifier applies consistent nesting and spacing so you can audit rules quickly.
Does it validate my HTML?
It formats, it does not validate. Malformed tags still need a validator; beautifying just makes them easier to find.
