XML Minifier & Compressor Online

Use this online minifier and compressor to reduce XML file size and speed up transfers. Write, paste or upload your .xml file and choose the options below. This online tool removes non essential characters and can preserve nodes or paths you mark while keeping the XML structure intact.

Core Features

  • Minify XML by removing redundant whitespace
  • Compress by collapsing attributes and inline text where safe
  • Preserve selected nodes using Exclude Nodes
  • Skip compression in specific nested fields with Ignore Paths
  • Runs entirely in the browser so your files never leave your machine

How to use the XML compressor

  1. Write, paste or upload your XML file into the editor
  2. Use Exclude Nodes or Ignore Paths to protect parts of the document if needed
  3. Click Minify XML to run the tool
  4. Copy the minified output or download it as a .xml file

Why Minify XML

  • Smaller XML files reduces transfer time for APIs and integrations
  • Minified files are useful for constrained devices and embedded systems
  • Compression lowers bandwidth and storage needs
  • Keep readable source files for development and use minified builds in production
