What does XML Minifier do?

XML Minifier removes unnecessary spacing from XML while preserving markup meaning.

  • Primary use: XML Minifier removes unnecessary spacing from XML while preserving markup meaning.
  • Key technical fact: Whitespace can be meaningful in XML text nodes, so XML minification must avoid changing content data.
  • Practical check: Run the formatted or minified output through your parser, tests, or runtime when exact syntax behavior matters.

Compact XML without flattening meaningful text

XML Minifier removes avoidable indentation and line breaks so XML takes less space. It is useful for compact examples, embedded XML strings, request bodies, and generated configuration snippets.

Whitespace inside text nodes can be meaningful in XML, especially in mixed content, preformatted text, CDATA, and signed documents. Minify only when the consumer does not depend on exact whitespace or canonical XML output.

How to use

  1. Paste your XML data into the input editor.
  2. Click Minify XML to remove avoidable formatting whitespace.
  3. The minified XML appears in the output editor as compact markup.
  4. Use Copy for the clipboard, Download for a file, or Clear to reset.

What is XML Minifier?

XML Minifier is a browser-based utility for turning formatted XML into a smaller text representation. It keeps tags, attributes, and element content while reducing presentation whitespace where possible.

Unlike JSON minification, XML minification has more caveats because text nodes and whitespace-only nodes may carry meaning for some applications. Validate the output with the target parser before using it in production workflows.

Input notes

Use well-formed XML and avoid minifying documents where signatures, canonicalization, or exact text spacing matter. Remove copied labels or transport headers before processing.

Example

A simple element tree can be compacted by removing indentation between tags:

--- Formatted Input ---

  John
  30


--- Minified Output ---
John30

MCP integration

MCP (Model Context Protocol) lets AI agents and apps discover and run Coding.Tools utilities for repeatable conversions, formatting, hashing, and generation workflows.

MCP tool name: xml-minifier

MCP endpoint: https://coding.tools/mcp

Call tools/list first. Each tool entry includes inputSchema, outputSchema, and examples so an AI agent or client can build valid arguments without guessing.

For tools/call, read result.content[0].text for the display value and result.structuredContent for machine parsing. Tool-level failures return isError: true; protocol failures return a JSON-RPC error.

Example tools/call request:

curl -s https://coding.tools/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "MCP-Protocol-Version: 2025-06-18" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"xml-minifier","arguments":{"input":"<invoice>\n  <id>1001</id>\n  <total>58.40</total>\n</invoice>"}}}'

Most text and data tools accept an input string plus optional options. Browser-only image tools are listed for discovery and return a web UI link when they need browser image APIs.
