Regex Obfuscator
Obfuscate regular expression patterns using 6 different techniques: convert character classes to alternation groups, expand shorthand escapes (\\d → [0-9], \\w → [a-zA-Z0-9_]), convert quantifiers to verbose forms (+ → {1,}), convert escape sequences (\\t → \\x09), inject redundant non-capturing groups with empty group anchors, or apply full multi-layer obfuscation. Each technique produces an equivalent regex with identical matching behavior. Includes live test validation against sample strings, per-method size impact analysis, and one-click copy. Free, private, and no signup required.

Enter a regex pattern above to obfuscate it using 6 different techniques. Choose from character class → alternation, shorthand expansion, quantifier conversion, escape sequence conversion, redundant groups, or full multi-layer obfuscation. Click any example pattern to get started, then use the test panel to verify that obfuscated patterns still match correctly.
