Find and Replace Text

What this tool does

Find and Replace Text scans whatever you paste and swaps every match of your search term for a replacement — all at once. It is the same idea as the find-and-replace box in a word processor, but stripped down, instant, and completely private. Your text never leaves your browser: there is no upload, no server, and nothing is stored. Close the tab and it is gone.

Three switches let you tighten or loosen how matching works. Case-insensitive treats "Fox", "fox", and "FOX" as the same word. Whole word only stops "cat" from matching inside "category" or "scatter". And Regular expression unlocks full pattern power — use \d+ to catch any run of digits, \s+ to collapse whitespace, or capture groups referenced as $1 in your replacement.

How to use it

1. Paste or type your text into the first box.
2. Type the word or phrase you want to find in the Find field.
3. Type what it should become in the Replace with field (leave it blank to delete matches).
4. Optionally tick Case-insensitive, Whole word only, or Regular expression.
5. Read the count of how many occurrences were replaced, then click Copy result to grab the output.

FAQ

Does it replace every match or just the first?

Every match in the text is replaced in a single pass, and the tally below the buttons tells you exactly how many were changed.

Can I use regular expressions?

Yes. Tick Regular expression and your Find field is read as a regex pattern. You can reference capture groups like $1 in the replacement. Invalid patterns show a friendly error instead of breaking.

Is my text uploaded anywhere?

No. Everything runs in your browser with JavaScript. Nothing is sent over the network, logged, or saved.

Why did "cat" not match inside "category"?

You likely have Whole word only enabled, which requires a word boundary on both sides. Untick it to match anywhere, including inside longer words.
