XML Formatter & Beautifier

Paste messy XML to pretty-print it with clean indentation, or minify it down to a single line. Malformed markup is flagged with a precise parse error.

🔒 100% private — nothing is uploaded, it runs entirely in your browser

How it works

Everything happens locally in your browser using the built-in DOMParser and XMLSerializer — there is no server round-trip, so even large or sensitive documents stay on your machine.

1

Beautify

Paste XML and hit Beautify to re-indent every element and node on its own line, making nested structures easy to read.

2

Minify

Minify strips the whitespace between tags to shrink the payload for transport or storage, in one click.

3

Validate

Malformed XML is caught by the parser and reported with the error message and location, so you can fix it fast.

🔒

Private by design. Your XML is parsed and formatted entirely in your browser with native JavaScript. Nothing is ever uploaded, logged, or seen by us.

Frequently Asked Questions

What's the difference between Beautify and Minify?
Beautify re-indents your XML so every element sits on its own line and nested structure is easy to read. Minify strips the whitespace between tags to shrink it down to a compact single line.
Can I choose the indentation?
Yes. Pick 2 spaces, 4 spaces or tabs, and optionally collapse blank lines. Beautify then uses that setting for the formatted output.
What happens if my XML is invalid?
The parser catches malformed markup and shows a clear error message describing what went wrong, so you can find and fix the problem quickly.
Does it keep my comments and CDATA?
Yes. Comments, CDATA sections, processing instructions and any XML declaration are preserved — only the layout changes, not the content.
Can I save the result?
Yes. Copy the formatted XML to your clipboard with one click, or download it as an .xml file.
Is my XML uploaded to a server?
No. Your XML is parsed and formatted entirely in your browser — nothing is ever uploaded, logged or seen by us, so even sensitive documents stay on your machine.
