Features

Add as many find-replace rules as you need. All rules are applied in order with a single click — replace many patterns in one operation.

Enable the .* toggle to use regular expressions. Supports all standard JS regex syntax including capture groups and lookaheads.

Switch to Preview mode to see matches highlighted in red before replacing — giving you confidence before modifying the original text.

Per-rule flags: Aa for case sensitivity, W for whole-word matching. Mix and match per rule for precise text substitution control.

Made a mistake? Click Undo to instantly revert the last Replace All operation and seamlessly restore your original text state.

Every replacement is logged with the search term, replacement, and match count — so you always know what changed and when.
