Free Find and Replace Tool – Search & Replace Text Online

Yes. The tool keeps a full history of changes, so you can click Undo to revert the last replacement and undo multiple times to step back through your entire replacement history. This acts as a safety net when a broad pattern replaces more than you intended, letting you revert and refine.

Whole word matching only finds the search term when it appears as a complete standalone word, not as part of a larger word. For example, searching for 'cat' with whole word enabled will not match 'category', 'concatenate', or 'scattered'. This prevents accidental replacements inside unrelated words.

Yes. Enable the 'Case sensitive' option to match exact capitalization. With it turned on, searching for 'Hello' will not match 'hello' or 'HELLO' — only an exact-case occurrence is found and replaced. This is useful when capitalization carries meaning, such as in code or proper nouns.

There is no fixed limit. The tool can handle documents with thousands of matches and replace them all instantly, because it processes the text entirely in your browser's memory. Very large documents work fine, with the practical limit being your device's available memory rather than any server cap.

Yes, with regex enabled. Use \n for newlines, \t for tabs, \s for any whitespace, and \d for digits in your search pattern. This lets you replace invisible formatting characters that you cannot easily type, such as collapsing multiple blank lines or converting tabs to spaces across an entire document at once.

The match count tells you exactly how many places will change before you commit. If you expected to replace a word a handful of times but see hundreds of matches, your search term is probably too broad or matching inside other words. Reviewing the count first prevents unintended bulk changes.

Yes. All searching and replacing happens locally in your browser using JavaScript. Your text is never uploaded to a server or stored, so it is safe to edit confidential code, contracts, and personal documents.
