Find & Replace
Find and replace text instantly. Supports case-insensitive matching and regular expressions, free and private, right in your browser.
Paste in text, code, or a list and swap every occurrence of one string for another in one pass, with an optional regex mode for pattern matching, capture groups, and bulk cleanups that plain find-and-replace can't handle.
How to use it
- Paste your text into the input box
- Enter what to find and what to replace it with (enable regex for patterns)
- Copy the updated text or download it
Frequently asked questions
- Can I use regular expressions?
- Yes. Turn on regex mode and use capture groups like (\w+) in your search pattern, then reference them in the replacement with $1, $2, etc.
- Does it replace across a whole file or just what I paste in?
- It works on whatever text you paste or type into the box. Paste in a full document, log file, or CSV and it replaces every match at once.
- Is my text uploaded anywhere?
- No. Everything runs locally in your browser tab, so pasted text, code, or logs never leave your device.
- What's the difference between case-sensitive and case-insensitive matching?
- Case-sensitive mode only matches exact letter casing (e.g. "Cat" won't match "cat"); toggle it off to match regardless of case.

Nothing is uploaded
The file never leaves your device. There is no server to send it to, so there is nothing to leak, log, or subpoena.
