How to Use
Simple 4-step process
Step 1
Paste your XML code directly into the input area or upload an XML file (.xml) using the upload button.
Step 2
Choose between Minify or Format mode using the toggle buttons. Click Settings to customize options like comment removal, whitespace collapsing, and indentation size.
Step 3
View the processed XML in real-time. Check the statistics panel (when minifying) to see file size reduction and compression percentage. Use side-by-side or tabbed view modes for comparison.
Step 4
Copy the processed XML to your clipboard with one click, or download it as a new XML file. The tool automatically generates optimized or formatted XML.
Frequently Asked Questions
Everything you need to know about our process, pricing, and technical capabilities.
See Full FAQXML minification removes unnecessary characters (whitespace, comments) to reduce file size, while formatting adds proper indentation and structure for readability. Both are important because: Minification reduces file size for faster data transfer and API responses Formatting improves code readability and maintainability Both help optimize XML-based applications and web services Reduces bandwidth usage and storage costs
No, our XML minifier preserves all XML structure and functionality while removing only unnecessary characters. The minified XML will behave exactly the same as your original XML, just with a smaller file size. However, we recommend testing the minified XML in your development environment before deploying to production.
The tool offers two modes: Minify: Removes whitespace, comments, and unnecessary characters to reduce file size Format: Adds proper indentation, line breaks, and structure to improve readability You can switch between modes at any time to suit your needs.
Yes! In Format mode, you can adjust the indentation size (1-8 spaces) in the Settings panel. This allows you to customize the formatting to match your project's coding style preferences.
The tool processes XML and will show errors if the XML structure is invalid. However, for production use, we recommend using a dedicated XML validator to ensure your XML conforms to specific schemas or DTDs.
File size reduction varies depending on your XML. Typically, you can expect 20-50% reduction with standard minification. The actual reduction depends on factors like the amount of whitespace, comments, and formatting in your original XML.
Yes! The tool handles XML with namespaces, attributes, and complex nested structures. Both minification and formatting preserve namespace declarations and all XML features.
Yes, the processed XML is production-ready and can be used directly in your applications. However, we always recommend keeping a backup of your original XML file and testing the processed version thoroughly before deploying to ensure everything works as expected.
