XML Minifier Online
Remove unnecessary whitespace between XML tags.
Compact XML markup while preserving element and attribute content. Paste the input, make the change, then read the result before you copy it elsewhere.
Whitespace inside text nodes can be meaningful.
Ready — input is processed locally.
This utility runs on the current device for the supported workflow. Kaazo does not need the pasted input to calculate the result.
XML Minifier: what the result contains
Compact XML markup while preserving element and attribute content.
Whitespace can be cosmetic — until mixed text content uses it
Most machine-oriented XML tolerates formatting changes around elements, but documents that mix text and child elements can treat spaces as meaningful content.
Keep a formatted copy for editing.
reduce example payload size
One straightforward use is to reduce example payload size. Another is to compact configuration snippets. The common thread is that the input already contains the information the tool needs.
Where XML Minifier stops
Don’t minify XML blindly when whitespace inside text nodes is significant to the application consuming it.
Example and result checks
An XML configuration may contain indentation solely for readability. In a paragraph-like element, however, spaces between text and nested tags can be part of the intended sentence. Compare the structured result before and after compaction, and do not strip spaces from fields that carry human-readable content.
Check that declarations, namespaces, CDATA and attribute values survive exactly as required by the receiving application. A minifier is not a schema validator: an XML document can be compact and well-formed yet still violate the rules of the software consuming it. Keep a formatted source copy.
FAQ
What does XML Minifier actually do?
Compact XML markup while preserving element and attribute content.
What limitation matters most?
Most machine-oriented XML tolerates formatting changes around elements, but documents that mix text and child elements can treat spaces as meaningful content. Keep a formatted copy for editing.
Does formatted or converted output prove the data is valid for my application?
No. XML Minifier can perform the syntax or data operation described here, but your application can still impose its own schema, business rules, encoding or security requirements.
