Email Deobfuscator

Decode Any Obfuscated Email

The Email Deobfuscator is the inverse of obfuscation: paste in HTML entities, Base64 strings, [at]/[dot] text, ROT13, reversed text, or a full HTML snippet, and the tool tries every decoding strategy and returns the emails it recovers.

Supported Inputs

• Plain text — [email protected] in any surrounding text.
• HTML — <a href="mailto:..."> snippets, with tags stripped.
• HTML entities — co... or co....
• [at] / [dot] substitutions — contact [at] example (dot) com, user at domain dot com.
• Base64-wrapped — looks for long base64 tokens anywhere in the input and tests whether decoding yields a valid email.
• ROT13 — tries the ROT13 transform on the input.
• Reversed — tries reversing the entire string.

How It Reports Results

Each match is shown with a label of the method that exposed it. The same email may appear more than once under different methods — that's fine; it confirms the decoding is robust.

Common Uses

• Recover contact addresses from copied web pages
• Test that your own obfuscation holds up against simple decoders
• Inspect suspicious messages that try to hide addresses from filters
• Audit scraped datasets for embedded PII

Limitations

• Multi-layer obfuscation (entities inside Base64, for example) is handled when the patterns compose cleanly; unusual stacking may still require a manual step.
• Custom per-site JavaScript decoders are not executed — paste the rendered DOM text if you can, or the raw string fed to the decoder.
