About the Find & Replace Text
This find and replace tool swaps every match of a word or pattern with your replacement text in one step.
Turn on regex to use regular expressions, including capture groups in the replacement, or keep it off to match plain text exactly.
Optional case-insensitive and whole-word modes give you precise control, and the tool reports how many replacements were made.

Frequently asked questions
- Can I use capture groups like $1?
- Yes. In regex mode you can reference capture groups such as $1 in the replacement field to reuse matched parts.
- What does whole word do?
- Whole word only matches your text when it stands alone, so replacing cat will not affect the word category.
- Is my text uploaded anywhere?
- No. Replacement happens entirely in your browser, so your text never leaves your device.
