HTML Beautifier
Make compact HTML easier to read with basic indentation.
Make compact HTML readable
Minified or machine-generated HTML — one long line, inconsistent nesting — is hard to read and edit. This beautifier adds basic indentation so the structure of the document becomes visible again, making it far easier to review or modify.
Re-indenting reveals the nesting that minification hides, without changing what the markup renders. Paste compact HTML, get a formatted version, and copy it back into your editor to work with a document you only had in compressed form.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
