Online HTML Beautifier - Format and Clean HTML Code

Formatting HTML

This tool reformats HTML into a readable shape: indentation is made consistent and line breaks are placed sensibly.

The behaviour of the code does not change. Only its presentation is altered, never its meaning.

How to use it

Paste your HTML into the input field and run the tool, then copy the result.

If the code has a syntax error, formatting may stop at that point — check the syntax first in that case.

What it is useful for

Formatted code is easier to read, review and compare against another version — especially for files that were minified beforehand.

It also helps when adopting a snippet from elsewhere, since consistent indentation makes the structure obvious at a glance.

Frequently asked questions

Does formatting change my output?

No. Only the way the code is written changes; what it does stays the same.

Can I reverse the process?

Formatted code can always be minified again, though comments removed earlier do not come back.

Does my code leave the device?

Processing runs in the browser. Even so, avoid pasting credentials or API keys, which sometimes end up inside code samples.
