Base64 to XML Converter

The Base64 to XML Converter is an online tool that converts Base64 encoded data to XML format and vice versa. This tool is essential for developers working with encoded XML data, API integrations, data transmission, and systems that store XML in Base64 format.

What is this tool for?

Our Base64 to XML Converter tool is perfect for developers, system administrators, and anyone working with encoded XML data. Whether you're decoding Base64-encoded XML from APIs, converting XML to Base64 for transmission, or working with encoded configuration files, this tool simplifies the conversion process.

Common use cases include:

Decoding Base64-encoded XML from web APIs and services
Converting XML data to Base64 for safe transmission
Working with encoded XML in databases and configuration files
Debugging Base64-encoded XML responses
Converting XML to Base64 for embedding in JSON or other formats
Processing encoded XML in data pipelines

How to Use the Tool

Select Conversion Mode: Choose between "Base64 → XML" (decode) or "XML → Base64" (encode) using the swap button.
Enter Input:
- For Decoding: Paste your Base64 encoded string in the input field
- For Encoding: Paste your XML data in the input field
Upload File (Optional): Use the file upload button to load data from a file.
View Output: The converted output appears automatically in the output panel.
Copy or Download: Use the copy button to copy the result, or download it as a file.

Understanding Base64 Encoding

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data for transmission over text-based protocols or to store binary data in text formats like JSON or XML.

Encoding: Converts binary data (or text) into a Base64 string
Decoding: Converts a Base64 string back to its original format
Character Set: Uses A-Z, a-z, 0-9, +, /, and = for padding
Size Increase: Base64 encoding increases data size by approximately 33%

Example

Base64 Input:

PD94bWwgdmVyc2lvbj0iMS4wIj8+PHJvb3Q+PGhlbGxvPldvcmxkPC9oZWxsbz48L3Jvb3Q+

Decoded XML Output:

<?xml version="1.0"?>
<root>
  <hello>World</hello>
</root>

Frequently Asked Questions

What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format using 64 characters (A-Z, a-z, 0-9, +, /). It's commonly used to encode data for transmission over text-based protocols or to store binary data in text formats.

Can I convert XML to Base64 as well?

Yes! The tool supports bidirectional conversion. Use the swap button to switch between "Base64 → XML" (decode) and "XML → Base64" (encode) modes. You can convert in either direction.

What if my Base64 string contains whitespace?

The tool automatically removes whitespace from Base64 input before processing, so you can paste Base64 strings with or without spaces, newlines, or other whitespace characters.

Does the tool validate the decoded XML?

Yes, the tool attempts to parse the decoded content as XML. If the decoded content is not valid XML, it will still display the decoded text but may show a warning. The tool will format valid XML for better readability.

Can I upload files for conversion?

Yes! You can upload files containing Base64 data or XML content using the file upload button. The tool will automatically load the file content and convert it.

Is my data safe?

Yes, all conversions are performed locally in your browser. Your data is never sent to any server, ensuring complete privacy and security. You can safely convert sensitive or proprietary data.

What happens if I enter invalid Base64?

The tool validates Base64 format before decoding. If the input is invalid, you'll receive an error message explaining the issue. Make sure your Base64 string contains only valid Base64 characters (A-Z, a-z, 0-9, +, /, =).
