About Find and Replace
Free online find and replace tool. Bulk-replace text with plain-string or regular-expression matching, case-sensitive or not. Supports capture-group backreferences ($1, $2) in the replacement string. Runs entirely in your browser. Find and Replace on 712 Tools runs entirely inside your browser using modern JavaScript APIs — no server ever sees your data. That means instant results, complete privacy, and no upload limits.
Whether you need to bulk find and replace text with regex support for a debugging session, a quick sanity check, or a production incident, this tool is free to use as many times as you need. There are no watermarks, no sign-up, and no ads inside the tool itself.
Frequently asked questions
Can I use regular expressions?
Yes. Toggle 'Regex mode' to interpret the find pattern as a JavaScript regex. Use $1, $2 in the replacement for capture groups.
Is find case-sensitive by default?
Yes. Toggle 'Ignore case' to match regardless of case.
How do I replace only the first occurrence?
Turn off 'Replace all' — only the first match is replaced. Global replacement (all matches) is the default.
Is my text uploaded?
No. All matching and replacement happens locally via the browser's native string and RegExp APIs.
