About Find & Replace
Find and replace across a whole block of text, with optional regular-expression mode. Switch on regex to use patterns and capture-group references ($1, $2) in the replacement, toggle case-insensitive matching, and enable dotall so '.' spans line breaks.
A live match count tells you how many replacements were made, and invalid patterns are reported instead of failing silently.
What people use it for
Bulk-rename a term throughout pasted text or code.
Use a regex with capture groups to reformat dates, names or IDs.
Strip or swap a repeated token case-insensitively.
Frequently asked questions
Does it support regular expressions?
Yes — toggle regex mode for full pattern matching, including $1/$2 group references in the replacement.
Can I ignore case?
Yes, with the ignore-case toggle, plus a 'dot matches newline' option for multi-line patterns.
Is it private?
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
