FAQ
How do I find and replace using a regex?
Enable the regex option, type your pattern in the search field, then the replacement text. You can use capture groups and reference them in the replacement with $1, $2, and so on.
Is the search case-sensitive?
By default the search is case-sensitive, but you can make it case-insensitive via the dedicated option (or the i flag in regex mode) so uppercase and lowercase are treated the same.
Is my data sent to a server?
No. The entire find-and-replace runs locally in your browser. Your text is never transmitted, so you can safely process sensitive content.
