XML Minifier: Remove Whitespace and Reduce File Size
XML Minifier removes insignificant whitespace from XML to create a more compact result, while preserving CDATA sections and regions marked with xml:space="preserve". You can choose whether to remove comments and the XML declaration, then compare the original and minified sizes by bytes saved and percentage. Paste or drop XML to produce a smaller version for sharing or compact payloads.
XML Minifier is a browser-based XML minifier that removes insignificant whitespace to create a more compact document. Paste or drop XML into the tool, then review the minified result alongside the bytes saved and percentage reduction. These size figures help you decide whether the smaller output is useful for your situation.
The conversion strips insignificant whitespace while preserving CDATA sections and regions marked with xml:space="preserve". You can also choose whether to remove comments and the XML declaration. These options let you control what stays in the result, and you can copy the compact XML once you have reviewed it.
XML uses tags and attributes to represent structured information, while whitespace, comments, and the XML declaration can also appear in a document. Minifying is useful when you want a more compact XML string for shipping, a URL, a header, or a configuration value. Since comments and the declaration can be removed separately, you can choose how much of that content to retain.
XML Minifier runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server; after the page has loaded, the tool works offline. It is free to use, making it useful for developers and DevOps engineers who want to quickly compact XML and check the size difference without sending the content elsewhere.
Step 1: Paste or drop your XML into the input area. The tool accepts XML content and prepares it for minification.
Step 2: Choose whether to remove comments and the XML declaration. These options let you control whether those parts remain in the compact output.
Step 3: Minify the XML and review the result. Insignificant whitespace is stripped while CDATA and xml:space="preserve" regions are preserved.
Step 4: Compare the original and minified sizes using the bytes-saved and percentage figures. Copy the compact result when it meets your needs.
Use case: Shrink XML before shipping it in an application or service. Removing insignificant whitespace can reduce the payload while preserving its meaning.
Use case: Check whether minification is worthwhile by comparing the original and compact sizes. The bytes-saved and percentage figures make the change easy to assess.
Use case: Create a compact XML payload for a URL, header, or configuration value. Copy the result for use wherever a smaller XML string is useful.
Use case: Prepare XML configuration files for storage or sharing. Choose whether comments and the XML declaration should remain in the output.
Use case: Review how much whitespace contributes to an XML document's size. The before-and-after figures help you make an informed choice about using the minified version.
Use case: Minify XML when you are offline after the page has loaded. The tool processes the input in your browser without sending it to a server.
