What is XML Minifier?
Need to shrink your XML file size? XML Minifier removes all unnecessary whitespace, line breaks, and comments from your XML files. Perfect for production environments where smaller file sizes mean faster transfers and lower bandwidth usage.
Minified XML is functionally identical to formatted XML but takes up less space. The minifier preserves all your data and structure while removing everything unnecessary. Great for API responses, config files, or any XML that needs to be compact.
Everything happens in your browser – your XML never leaves your computer. Minify, download, and use your compact XML right away.
What Makes This Tool Different
Whitespace Removal
Removes all unnecessary spaces, tabs, and line breaks. Your XML becomes a single compact line while staying perfectly valid.
Comment Removal
Strips out XML comments () to reduce file size further. Comments aren't needed for XML parsing, so removing them saves space.
Structure Preservation
All your XML structure stays intact. Elements, attributes, and values remain exactly the same – just without the formatting.
File Upload Support
Got a big file? Just upload it. Works great for minifying those massive XML configs or API responses without copy-pasting.
Download Minified XML
One click to download your minified XML file. Perfect for production deployments where smaller files mean better performance.
Syntax Validation
We validate your XML before minifying. Invalid XML gets caught early, so you know the minified version will work correctly.
How It Works
Paste or Upload XML
Paste your XML code into the left editor, or click "Upload" to load a file. You can also click "Sample" to see an example. The tool accepts any valid XML structure.
Automatic Minification
As soon as you paste, the minifier processes your XML and displays the compact version on the right. All whitespace and comments are removed, making it much smaller while staying valid.
Download or Copy
Click "Download" to save the minified XML file, or "Copy" to copy it to your clipboard. The minified XML is ready to use in production or wherever you need compact XML.
When You'd Actually Use This
Production Deployment
Minify XML config files before deploying to production. Smaller files mean faster loading times and reduced bandwidth usage.
API Optimization
Minify XML API responses to reduce payload size. Faster API calls and lower bandwidth costs, especially important for mobile apps or high-traffic APIs.
Storage Efficiency
Save storage space by minifying XML files. Great for archiving large amounts of XML data or when storage costs matter.
Network Transfer
Reduce transfer times by sending minified XML. Smaller files transfer faster, especially over slow connections or when dealing with large datasets.
Common Questions
Is my XML data stored?
Nope. Everything happens right in your browser. Your XML never leaves your computer – we don't even see it.
Does minification break my XML?
No. Minified XML is functionally identical to formatted XML. All elements, attributes, and values stay exactly the same – we just remove whitespace and comments.
How much smaller does it get?
It depends on how much whitespace and comments your XML has. Typically, you'll see 20-50% size reduction, sometimes more for heavily formatted XML with lots of comments.
Can I format it back?
Yep. Use our XML Formatter to make minified XML readable again. Minification is reversible – formatting just adds whitespace back.
What about CDATA sections?
CDATA sections are preserved exactly as they are. We only remove whitespace between elements, not content inside CDATA blocks.
Does it work with large files?
Yep. Since everything happens in your browser, it depends on your device. Small files minify instantly. Very large files (10MB+) might take a few seconds, but they'll still work.
Other XML Tools You Might Need
Minification is just one XML task. Here are other tools that work well together:
