Convert Base64 to XML

Base64 is how XML sneaks through email, JSON, URLs and databases. Convert Base64 to XML reverses the trip: it accepts raw or line-wrapped Base64 (and data URL prefixes), decodes the UTF-8 bytes, and hands back the original document.

An optional validation step parses the decoded text as XML, so you know immediately whether the payload you received is well-formed — or exactly what is wrong with it. Decoding happens entirely in your browser.

• Handles common formats: plain Base64, wrapped lines and data URL prefixes are accepted.
• UTF-8 decoding: international text and symbols are restored byte-exactly.
• Optional XML validation: parses the result and reports errors when it is not well-formed.
• Clear error reporting: invalid characters and padding are flagged with the reason.
• Live updates: decode as you type with the live toggle.
• Copy, download or print: the decoded XML is a click from your clipboard.
• Instant stats: see the decoded size and character count.
• Round-trip friendly: pair with the XML to Base64 tool to verify fidelity.
• Private by design: decoding runs locally, nothing uploaded.

1. Paste your Base64 or load it from a file.
2. Toggle XML validation if you want the result checked for well-formedness.
3. Review the decoded document in the output panel.
4. Copy or download the XML, or print it to PDF.

Example 1 — API responses. An API returns XML payloads as base64 strings. Decode to inspect the actual document, with validation on to catch malformed responses immediately.

Example 2 — Email debugging. Base64-encoded XML from MIME bodies decodes to the original file, ready for review or re-saving.

Example 3 — Database recovery. XML stored as base64 in legacy columns decodes back to readable documents for migration.

Example 4 — Verifying encoders. Decode output from any Base64 encoder and validate it as XML to confirm the pipeline is byte-faithful.

• Instant recovery — Base64 back to readable XML.
• Format-tolerant — wraps and data URLs handled automatically.
• Validated output — catch malformed XML at decode time.
• Round-trip proof — pair with the encoder to verify fidelity.
• Free and private — local decoding, nothing uploaded.
