XML Minify
Minify your XML by removing unnecessary whitespace and line breaks
I know that staring at XML full of spaces and line breaks can feel like leafing through a phone book. This XML Minify tool will help you strip all the extra whitespace so your markup is lean and mean.
What is an XML Minify?
XML Minify is a browser-based utility that compresses your XML by removing all spaces, tabs, and line breaks that serve only formatting purposes. It preserves the structure and data of your XML while making it as compact as possible. This makes transmission faster and reduces payload size without altering any element content or attributes.
What Does Our XML Minify Do?
When you paste valid XML into the input field and click Minify XML the tool uses a simple JavaScript function to collapse any whitespace between tags. It detects occurrences of “> <” and replaces them with “><” then removes all newline characters. The result is a single-line or tightly packed XML string in the output area. If you need to clear both fields you can click Clear All. All operations occur locally in your browser so your data remains private.
What to Expect When Using This Tool
On page load you will see two text areas side by side labeled XML Input and Minified Output. On mobile devices they stack vertically for easy use. Paste your XML into the left pane, click Minify XML, and view the compacted version in the right pane. The interface is straightforward with only two buttons: Minify XML and Clear All.
Common Use Cases
- Reducing network payload for XML-based APIs
- Embedding XML in HTML or scripts with minimal overhead
- Preparing RSS or Atom feeds for efficient delivery
- Cleaning up SOAP requests before sending
- Minimizing configuration files in XML format
Input and Output Examples
Example 1
Input:
<note>
<to>Alice</to>
<from>Bob</from>
<body>
Remember our meeting at 3pm today.
</body>
</note>
Output:
<note><to>Alice</to><from>Bob</from><body>Remember our meeting at 3pm today.</body></note>
Example 2
Input:
<items>
<item id="1">
<name>Item One</name>
<price>19.99</price>
</item>
<item id="2">
<name>Item Two</name>
<price>29.99</price>
</item>
</items>
Output:
<items><item id="1"><name>Item One</name><price>19.99</price></item><item id="2"><name>Item Two</name><price>29.99</price></item></items>
Frequently Asked Questions (FAQs)
What if my XML is not valid?
The tool will still remove whitespace but it does not validate or correct XML syntax. You should ensure your XML is well-formed before minifying.
Will it remove spaces inside text nodes?
The tool only targets whitespace between tags. Spaces inside element content or attribute values remain intact.
Can I use this tool on my phone?
Yes. The responsive layout ensures the text areas stack vertically for a smooth experience on small screens.
Does my XML leave my device?
No. All processing happens in your browser. Your data never goes to a server.
Can I adjust the minification rules?
At present the tool uses a fixed approach to collapse whitespace between tags. Custom rules are not supported.
How do I copy the output?
Select the Minified Output area and use your device’s copy command or context menu.
Can it handle large XML files?
It manages moderate-size XML content well. Very large files may affect performance depending on your browser.
Is there an undo option?
You can keep a copy of your original XML or use an XML formatter tool to re-beautify if needed.
Does it preserve attribute order?
Yes. The tool only removes whitespace and does not alter element or attribute order.
Benefits of Using Minified XML
- Faster transmission over network
- Reduced bandwidth usage
- Smaller file size for storage or embedding
- Cleaner embed in HTML or script tags
- Preserved data integrity without manual editing
Best Practices
- Validate XML syntax before minifying
- Keep a prettified copy for development and debugging
- Minify only for production or deployment
- Integrate minification into your build or deployment pipeline
- Avoid editing minified XML directly—work with the source
Getting Started
- Paste your XML into the XML Input box
- Click the Minify XML button
- Copy the compact XML from the Minified Output box
- Click Clear All to reset both fields
- Use the minified XML in your API calls or embeds
- Enjoy faster loads and leaner XML payloads!
