Find and Replace

Find and replace text across a block of text, with case-sensitive, whole-word, and regex matching — instantly in your browser.

About Find and Replace

Find and Replace scans a block of text for every occurrence of a word or phrase and swaps it for something else, with optional case-sensitive, whole-word, and regular-expression matching for more precise control. It's built for cleaning up copy, renaming a term across a document, or fixing a recurring typo without doing it by hand. Everything runs locally in your browser as you type; nothing you paste is ever sent to a server.

How to use it

  1. 1

    Paste your text

    Drop the text you want to edit into the input above.

  2. 2

    Enter what to find and what to replace it with

    Type the text to search for in "Find" and what it should become in "Replace with". Leave "Replace with" empty to delete every match.

  3. 3

    Choose your matching rules

    Turn on "Case sensitive" to require exact letter case, "Whole word" to skip matches inside longer words, or "Use regex" to search with a regular expression pattern.

  4. 4

    Copy the result

    The updated text and match count appear live below — use Copy result to grab it, or Clear to start over.

What it does

FAQ

Can I replace text with nothing to delete it?

Yes. Leave "Replace with" empty and every match of your find term is removed from the text.

What happens if my regex pattern is invalid?

The tool shows an error and leaves your text unchanged until the pattern is fixed — it never crashes or produces partial output.

Does this tool send my text anywhere?

No. All processing happens locally in your browser as you type. Your text is never uploaded, logged, or stored.
