Free Online HTML Beautifier
Turn one-line or messy HTML into an indented, readable document. It gives developers a quick browser-based way to solve a focused html beautifier task before moving the result into a project.
How to use the html beautifier
Paste your code in the box, adjust the options if you want, and press Format. Choose the indent, line width, how attributes wrap and how sensitive whitespace is, then press Format. Pre blocks keep their content as written.
Common mistakes
- Formatting inline text can add whitespace that shows on the page; use the CSS whitespace mode for pages you will ship.
- Unclosed or mismatched tags are reported with a line and column.
Frequently asked questions
What does whitespace sensitivity mean?
In HTML a space between inline elements shows on the page. "Like the browser" keeps those spaces, "Strict" keeps all of them, and "Ignore" lets the formatter add or remove them freely.
Are pre blocks safe?
Yes. The text inside pre and textarea is kept as written.
Is my HTML uploaded?
No. It runs in your browser.
How do I use this html beautifier tool?
Use the interactive controls above; processing stays in your browser and the result is intended as a practical starting point for development work.
