URL-decode XML

Percent-encoded XML arrives via URLs, redirects and API query strings — but it is unusable until decoded. URL-decode XML reverses the encoding, restoring the original document from its %XX sequences.

Decoding handles query-string conventions (optional + to space), tolerates malformed sequences in lenient mode, and can validate the result as well-formed XML. All of it happens locally in your browser.

• Standard percent-decoding: %XX sequences are converted back to UTF-8 text.
• Plus-to-space option: decode HTML form-style input correctly.
• Lenient mode: malformed sequences are preserved rather than causing failure.
• Optional XML validation: confirm the decoded result is well-formed.
• Live updates: decode as you type with the live toggle.
• Copy, download or print: the decoded XML is a click from your clipboard.
• Round-trip friendly: pair with the URL-encode tool to verify fidelity.
• Private by design: nothing leaves your browser.

1. Paste the percent-encoded text or load it from a file.
2. Enable plus-to-space if the input came from an HTML form or query string.
3. Turn on lenient mode for dirty input that a strict decoder rejects.
4. Toggle XML validation to confirm the result is well-formed.
5. Copy or download the decoded XML.

Example 1 — URL analysis. Decode an XML fragment embedded in a URL parameter to see exactly what the server received.

Example 2 — Form payloads. Percent-encoded XML from HTML forms decodes correctly with plus-to-space enabled.

Example 3 — Log forensics. Decode encoded payloads captured in logs to reconstruct the original documents and validate them.

• Reconstructs originals — encoded XML back to readable text.
• Handles real-world input — plus handling and lenient mode.
• Validated output — confirm well-formedness at decode time.
• Instant and free — paste, decode, copy, done.
• Private by design — local decoding, nothing uploaded.
