Does this replace all occurrences, or just the first one?

All occurrences are replaced every time — there's no 'first match only' mode, matching how virtually every find-and-replace tool works by default.

What does the 'Use regex' toggle do?

When on, the 'Find' field is interpreted as a JavaScript regular expression instead of plain text, letting you match patterns (like any sequence of digits) rather than fixed text. The 'Replace' field can then reference capture groups from the pattern using $1, $2, and so on.

What does the 'Whole word' toggle do?

When on, matches are only counted if they fall on a word boundary — for example, searching for 'cat' with 'Whole word' on will match 'cat' but not 'category' or 'concatenate'. It works the same way in both plain text and regex mode.

Is search case-sensitive by default?

No — matching is case-insensitive by default, so searching for 'apple' also matches 'Apple' and 'APPLE'. Turn on 'Case-sensitive' if you need exact-case matching only.

Can I use a literal dollar sign in my replacement text?

Yes — in plain text mode (regex off), a $ in the Replace field is always treated as a literal character. Capture-group references like $1 are only interpreted specially when 'Use regex' is turned on.

What happens if I enter an invalid regex pattern?

The tool shows a clear inline error message describing what's wrong with the pattern (for example, an unclosed parenthesis), and the output stays unchanged rather than the page breaking or showing garbled results.

Is this the same regex flavor as the Regex Tester tool?

Yes — both tools use JavaScript's native RegExp engine, so a pattern that works in one works identically in the other. Use Regex Tester to build and verify a pattern, then bring it here to apply it as a replacement.

Is my text uploaded to a server?

No. All searching and replacing happens locally in your browser using JavaScript. No network request is made, and nothing you type is stored or transmitted.

Find & Replace — Free Online Text Find and Replace Tool

Our Find & Replace tool searches your text for every occurrence of a search term and replaces it with new text, updating live as you type. Turn on 'Use regex' to search with a JavaScript regular expression instead of plain text — including capture-group references like $1 in the replacement — for pattern-based replacements a simple text search can't do. Case-sensitive and whole-word toggles give you precise control over what counts as a match. A live count shows how many replacements were made, and an invalid regex pattern shows a clear inline error instead of breaking the page. Nothing is uploaded — everything runs instantly in your browser.

Quick Answer

A Find & Replace tool searches text for every occurrence of a search term and replaces it with new text instantly, right in your browser. Optional regex mode lets the search term be a pattern with capture-group support, and case-sensitive/whole-word toggles control exactly what counts as a match. Free, and nothing you type is ever uploaded.

How to Use the Find & Replace

1
Paste or type your text into the input box.
2
Type the text (or regex pattern) you want to find into the 'Find' field.
3
Type the replacement text into the 'Replace' field — leave it empty to delete matches.
4
Toggle 'Use regex', 'Case-sensitive', or 'Whole word' as needed; the output and match count update instantly.
5
Click 'Copy' to copy the result.

Why Use Find & Replace?

Renaming a variable across a pasted code snippet, fixing a misspelled word repeated throughout a document, swapping a URL across a list of links, or normalizing inconsistent formatting all come down to the same task: find every occurrence of something and replace it with something else. Doing this by hand with manual select-and-retype is slow and error-prone once there are more than a couple of occurrences. This tool replaces every match instantly and updates live as you adjust your search term, replacement text, or options — no 'Replace All' button to click, no risk of missing an occurrence. For more advanced cases, an optional regex mode turns the Find field into a full JavaScript regular expression, letting you match patterns rather than fixed text and reference captured groups in the replacement (for example, replacing every email at 'example.com' with the same name at 'company.com' using a single pattern with a capture group). Case-sensitive and whole-word toggles apply consistently whether you're doing a plain text search or a regex one, and an invalid regex pattern is caught immediately with a readable error rather than corrupting your text or crashing the page.
