Find & Replace
Find and replace text — plain or regex, live as you type.
Your replaced text appears here
Paste text on the left, type what to find and what to replace it with, and the result updates live in your browser — with nothing sent to a server.
Runs entirely in your browserFind and replace text, locally
Paste any text, type what you want to find, and type its replacement — the result updates live and shows how many matches were replaced. Turn on case-insensitive matching to ignore capitalization, whole-word mode so a search for "cat" does not touch "category", or regex mode to use patterns and capture groups like $1. An invalid regular expression is reported gently instead of breaking the page. Everything runs in your browser tab, so your text never leaves your device and nothing is stored.
Common questions
Does it replace every occurrence or just the first?
Every occurrence. The replacement is applied globally across the whole text, and the match count shows exactly how many were changed.
How does regex mode work?
Turn on the regex option and your find field is treated as a JavaScript regular expression. You can use patterns, character classes, and capture groups — reference a group in the replacement with $1, $2, and so on. An invalid pattern is flagged rather than applied.
What does whole-word mode do?
It only matches your search term when it stands alone as a word, using word boundaries. Searching for "cat" with whole-word on will not match inside "category" or "scatter".
Can I replace text with nothing to delete it?
Yes. Leave the replacement field empty and every match is removed from the text.
Is my text uploaded anywhere?
No. All searching and replacing happens in your browser as you type. Your text never leaves your device and nothing is saved.
