Free online XML minifier. Strip whitespace, comments, and CDATA from XML for production use. Fast, browser-based, no upload required.
Ready to minify
Paste XML and click MinifyPaste your XML document into the input panel on the left.
Toggle which elements to strip: comments, CDATA, or the XML declaration.
Click Minify XML, then copy the compressed output or download it as a file.
The XML Minifier removes unnecessary whitespace, newlines, and comments from XML documents — shrinking file size without changing the data structure. Ideal for production deployments, API payloads, and CI/CD pipelines.
No. All minification is handled server-side on our own infrastructure — your XML is processed instantly and never stored, logged, or shared with third parties.
No. The minifier only removes insignificant whitespace between tags and optional constructs like comments. The structure, element names, attribute values, and text content are fully preserved.
CDATA sections wrap raw character data that shouldn't be parsed as XML markup. Stripping them removes the CDATA wrapper and its contents. Only enable this if you're sure the CDATA content isn't needed in your output.
Yes! SVG files are valid XML. Paste your SVG markup into the input field and the minifier will compress it. For deeper SVG optimization (path simplification, etc.), try our SVG Optimizer tool.
The tool works well for XML documents up to several hundred KB when pasted directly. For very large files (MB+), consider a local CLI tool like xmllint with the --noblanks flag.
The XML declaration (<?xml version="1.0" encoding="UTF-8"?>) identifies the document as XML and specifies its encoding. It's optional in XML 1.0 — strip it if your consumer doesn't need it, but keep it when encoding matters.
An XML minifier is a tool that compresses XML documents by removing human-readable formatting that serves no functional purpose in production environments. When developers write XML, they naturally indent nested elements, add blank lines between sections, and leave descriptive comments throughout. These additions improve readability but add bytes that bloat file size and slow down network transfers.
An XML minifier strips all of this away — collapsing multiple lines of indented markup into a single continuous string with no gaps. The resulting document contains exactly the same data as the original, with identical element hierarchy, attribute values, and text content, but in the most compact representation possible.

At its core, XML minification applies a series of text transformations to an XML document:
</item>\n <item> becomes </item><item>.<!-- ... -->) carry no runtime meaning and can be safely stripped. They often contain developer notes, TODOs, or disabled markup that adds zero value to a production consumer.<?xml version="1.0"?>) is optional in many contexts. Some parsers and consumers don't require it, so removing it can shave additional bytes.XML is used extensively across the web and enterprise software — in configuration files, SOAP web services, RSS/Atom feeds, SVG graphics, Android layouts, Maven POM files, Spring configurations, and dozens of other contexts. In all of these, the cost of verbose XML adds up quickly:
These tools are opposites. An XML formatter (also called XML beautifier or pretty-printer) takes compact or unformatted XML and adds indentation, newlines, and structure — making it easy for developers to read and edit. An XML minifier does the reverse: it takes nicely formatted XML and strips all that formatting away for efficient production use.
A typical workflow: receive raw XML from an API → format it with our XML Formatter to read and understand the structure → make edits → minify the result with this tool before deploying.
SVG (Scalable Vector Graphics) files are XML documents. Paste any SVG into this tool and it will compress the markup by removing whitespace and comments. This is a quick first pass — for deeper SVG optimization that also simplifies path data and removes redundant attributes, pair this tool with a dedicated SVG optimizer.
Many design tools export SVG with extensive comments, metadata, and formatting that inflates file size by 30–60% beyond the essential markup. Minification alone can make a significant dent in that overhead.
SOAP web services exchange XML messages that can become very large when formatted. Stripping whitespace from SOAP envelopes before transmission reduces payload size and can meaningfully improve throughput in high-volume integrations. Similarly, RSS and Atom feeds served to many subscribers benefit from minification to reduce egress bandwidth.
For teams building automated workflows, XML minification fits naturally into CI/CD pipelines. Tools like xmllint --noblanks, Python's lxml library, or Node.js XML packages can automate minification during build steps. This tool serves as a quick browser-based option for one-off minification tasks, prototyping, or verifying output before scripting the process.
