Frequently Asked Questions
What regex syntax is supported?▾
The tool uses JavaScript's RegExp engine, which supports character classes, quantifiers, anchors, groups, lookahead/lookbehind, and other standard regex features.
Can I use capture groups in the replacement?▾
Yes. When regex mode is enabled, you can reference capture groups in the replacement string using $1, $2, etc.
Is my text sent to a server?▾
No. All processing happens entirely in your browser. Your text never leaves your device.
What happens if my regex is invalid?▾
The tool displays an error message if the regex pattern is invalid, and no replacements are made until the pattern is corrected.
