About this tool

IconVault's Regex Replace is a live find and replace workbench for text. Enter a regex pattern with any JS flags, write a replacement string using $1 backreferences, $&, $$ and friends, and see a highlighted diff of every change update instantly as you type.

It shows the match count, flags pattern errors clearly, and gives you a copyable output in one click. Everything runs 100% in your browser, so large or private text never leaves your device, and it is free with no signup.
