What Convert Base64 to XML can do:

Convert Base64 to XML lets you decode Base64-encoded XML data back into usable markup. It handles embedded XML often seen in APIs, data URIs, logs, and stored config formats. The tool decodes your input, parses it as XML, and shows you a clean, readable version in real time. It also validates the result to catch malformed Base64 or invalid XML before exporting.

Everything runs in your browser nothing gets uploaded or shared making it ideal for sensitive data, testing, and development work.

Example:

Input Base64:

PD94bWwgdmVyc2lvbj0iMS4wIj8+PG5vdGU+PHRvPlRvdmU8L3RvPjwvbm90ZT4=

Output XML:

<?xml version="1.0"?>
<note>
  <to>Tove</to>
</note>

Common Use Cases:

Use this tool to decode Base64-wrapped XML from APIs, extract embedded metadata from files, review encoded data logs, or verify obfuscated payloads. It’s perfect for developers working with data URIs, webhooks, or services that serialize XML as Base64.

Useful Tools & Suggestions:

Before decoding, you can run Validate XML to check if the result holds up structurally. And if you need a visual check after, try Highlight XML Syntax it makes scanning the decoded output way easier.
