How to use this tool

1. Paste your XML into the input box.
2. Check that the document is well formed before minifying.
3. Click the minify button to remove whitespace between tags.
4. Copy the compact XML output and use it where you need a single-line version.

Step by step, what happens

1. The tool reads your XML text exactly as pasted.
2. It removes line breaks and spaces that appear between tags, while keeping the tag structure intact.
3. It produces a compact XML string that is easier to store, transmit, or embed.
4. You can then copy the result and paste it into your app, test, or build step.

Worked example

Here is a small XML snippet with indentation and line breaks that gets compressed into one line.

Input: <note> <to>Ada</to> <from>Sam</from> </note>

1. The tool receives the indented XML and scans for whitespace between elements.
2. It removes the line breaks and extra spaces around the tags.
3. The text content inside the tags, like Ada and Sam, stays unchanged.

Tips and common mistakes

• This tool removes whitespace between tags, but it does not fix broken XML syntax.
• If your XML has spaces inside text values that matter, check the result carefully before using it.
• Minified XML is harder for people to read, so keep a formatted copy for editing.
• If you paste XML with comments or processing instructions, review the output to make sure it still matches your needs.
