String Replacer
Find & replace text
String Replacer: Find & replace text. A free, browser-based tool from DevToolbox that runs entirely on your own device: no upload, no account, no tracking.
About the String Replacer
Free online string replacer. Find and replace text with regex support, case sensitivity, whole word matching, and match highlighting. It is one of the string tools tools on DevToolbox, and like all of them it runs entirely in your browser.
Text is handled as Unicode throughout, so counts, transformations and comparisons behave correctly for accented characters, emoji and scripts beyond ASCII rather than assuming one byte per character.

- Paste the text you want to work on.

Questions
- Is my data uploaded anywhere?
- No. The tool is JavaScript that runs in the tab you already have open, and DevToolbox has no backend to send anything to. You can open the network tab and watch: after the page and its script load, nothing is sent while you work.
- Does it work offline?
- Once the page has loaded, yes. The tool needs no network access to do its job, so it keeps working if your connection drops. Reloading the page does need the network unless your browser has it cached.
- Is it free, and do I need an account?
- It is free and there is no account, no sign-in and no usage limit. There is nothing to register because there is no server keeping track of anything.
