Find and Replace Text
A fast online find-and-replace tool for any block of text. Replace every occurrence at once with live match counts, toggle case-sensitive matching, limit to whole words, or switch on full regular-expression mode for advanced patterns and capture-group replacements. Invalid regex is handled gracefully, and everything runs locally in your browser — your text is never uploaded.

Frequently Asked Questions
QDoes it replace all occurrences at once?
Yes. Every match is replaced in one pass and the live counter shows exactly how many replacements were made.
QCan I use regular expressions?
Yes. Enable Regex mode to use full JavaScript regular-expression patterns, including capture groups like $1 in the replacement field. Invalid patterns are flagged instead of breaking.
QIs my text sent to a server?
No. All find-and-replace processing happens entirely in your browser; nothing is uploaded.
