Frequently asked questions
Is my text uploaded to a server?
No. Every find-and-replace operation runs entirely in your browser using local JavaScript. Your text never leaves your device and is never sent to or stored on any server, so it stays completely private even for sensitive content.
How do I use regular expressions for find and replace?
Tick the 'Regular expression' checkbox and type a regex pattern in the Find box, such as \d to match any digit. In your replacement you can reference capture groups with $1, $2 and so on. If the pattern is invalid, the tool shows a clear error instead of failing silently.
Can I replace only the first match instead of every occurrence?
Yes. Uncheck the 'Replace all' option and only the first match will be replaced. You can also enable 'Case insensitive' to match text regardless of capitalization, and combine it with regex or literal matching as needed.
