Buy me a coffeeWhat is XML to Base64?
XML to Base64 turns readable XML markup into a reversible Base64 string. Encoding XML can make it easier to embed inside JSON fields, message queue attributes, environment variables, legacy SOAP wrappers, or systems that cannot safely carry angle brackets and line breaks.
This tool validates the XML before encoding so malformed tags, broken nesting, or unescaped characters are caught early. It also reports the root element, element count, character count, and byte size before generating the encoded output.
How to Use XML to Base64
Paste XML into the input area
Fix any XML validation error shown by the parser
Enable URL-safe Base64 if the output will be used in a URL or filename
Click Encode XML to Base64
Copy or download the encoded result
Common Use Cases
- Encoding XML request bodies before wrapping them in JSON.
- Preparing XML fixtures for config files or environment variables.
- Moving XML through logs or queues where raw angle brackets are inconvenient.
- Creating test payloads for systems that expect Base64-encoded XML.
- Checking XML validity before handing encoded content to another service.
Example Input and Output
A compact XML order element encoded as Base64 for transport in a text-only field.
<order id="A100"><total>42.50</total></order>PG9yZGVyIGlkPSJBMTAwIj48dG90YWw+NDIuNTA8L3RvdGFsPjwvb3JkZXI+Encoding scope
The output can be decoded back to the original XML. Use encryption or signing separately when confidentiality or tamper resistance matters.
Frequently Asked Questions
Does the tool validate XML before encoding?
Yes. XML must be well-formed before the Base64 output is generated. This catches common issues like unclosed tags, mismatched nesting, and unescaped ampersands.
Is Base64 secure for XML?
No. Base64 is reversible encoding, not encryption. Anyone can decode the XML, so do not treat the output as protected data.
What does URL-safe output change?
URL-safe Base64 replaces + and / with - and _ and removes padding, making the value easier to place in URLs and filenames.
Is my XML uploaded?
No. XML validation and Base64 encoding happen locally in your browser.
