Find & Replace

Find every occurrence of a word or pattern in your text and replace it, with a match count and support for plain-text, whole-word, case-sensitive, and regular-expression modes -- entirely in your browser.

Runs in your browser Private & secure Updated August 10, 2026

Find and replace searches your text for every occurrence of a word or pattern and swaps it for something else — with a match count shown before you commit. It supports plain text, whole-word, case-sensitive, and regular-expression modes, entirely in your browser.

How this works

Type what you’re looking for and what to replace it with, then click Replace. Plain text mode matches the exact characters you type; whole-word mode only matches when your search term isn’t part of a larger word; regular-expression mode lets you match patterns rather than exact text, with capture groups ($1, $2…) available in the replacement. Malformed or dangerously complex regular expressions are rejected with a plain-language explanation rather than a raw error — nothing is ever executed as code, patterns are only ever compiled as regular expressions.

FAQs

Does it replace everything at once?

Yes — clicking Replace swaps every match in one step.

Can I delete text instead of replacing it?

Yes — leave the replacement field empty and every match will be removed.

What is a regular expression?

A regular expression (or "regex") is a pattern that matches text by structure rather than exact characters — for example, matching any sequence of digits instead of one specific number.

What does $1 mean in the replacement field?

In regex mode, parts of your pattern wrapped in parentheses are "capture groups." $1 refers to whatever the first group matched, $2 the second, and so on — letting you rearrange or reuse parts of the matched text.

Is my text uploaded anywhere?

No. This tool runs entirely in your browser — your text is never sent to a server, uploaded, or stored anywhere.
