Does minifying XML change its meaning?

No. Minification only removes insignificant whitespace and line breaks between elements. The element structure, attributes, and text content stay exactly the same, so the document remains well-formed and equivalent.

Is my XML data uploaded to a server?

No. All minifying and formatting runs entirely in your browser. Your XML never leaves your device, which makes the tool safe for sensitive or proprietary data.

How much smaller is minified XML?

It depends on how heavily your XML is indented, but removing indentation and line breaks from a deeply nested document commonly reduces its size by 20 to 50 percent, lowering bandwidth and speeding up transfers.

Can I reformat XML that has already been minified?

Yes. Paste minified XML into the input and click Format to re-add consistent indentation and line breaks, making the markup readable again for debugging and reviews.
