Find and Replace Text Online

Literal mode matches your exact text, so a dot only matches a dot and special characters lose their meaning. Regex mode compiles the find field as a JavaScript regular expression, so you can match digits, word boundaries, or repeated characters.

When 'Case sensitive' is on, the default, 'Apple' and 'apple' are treated as different strings. Untick it and the search adds the ignore-case flag, so a word matches regardless of how it is capitalized.

Yes. Untick 'Replace all' to change just the first occurrence in the text. Leave it ticked, the default, to replace every match. The counter reflects whichever mode you choose.

Standard JavaScript regex works. For example \d+ matches runs of digits, \s+ matches whitespace, and \bword\b matches a whole word. Anchors, character classes, and quantifiers are all supported.

Yes. In regex mode, parentheses in the find field create groups you can reuse with $1, $2 and so on in the replacement. Finding (\w+) (\w+) and replacing with $2 $1 swaps two words around.

Nothing changes. An empty find string returns your text untouched with a count of zero, so you never accidentally flood the output with the replacement value.

If the pattern cannot be compiled, the tool shows an 'Invalid regular expression' message in red and leaves your text unchanged, so a typo in a pattern never mangles the input.

There is no fixed cap. Because the work happens in your browser, the practical limit is your device memory. Very large regex patterns with heavy backtracking can be slow, but ordinary find and replace stays instant.

Yes. Everything runs locally in your browser and nothing is uploaded to a server, so confidential text and the terms you search for never leave your device.
