Frequently asked questions
Is my text data stored or sent to a server?
No. All find and replace operations happen entirely in your browser using JavaScript. Your data never leaves your computer, ensuring complete privacy and security.
What is regex mode?
Regex (regular expressions) allows pattern matching with special characters like *, +, ?, etc. for advanced find and replace operations.
How does case sensitivity work?
When enabled, "Hello" and "hello" are treated as different. When disabled, they are treated as the same.
Can I undo a replace operation?
The original text remains in the input box. You can always go back to it or clear and start over.
Does it count how many replacements were made?
The tool shows the result immediately. You can compare input and output to see changes.
Can I use this tool offline?
Yes, once the page loads, the tool works completely offline since all processing happens in your browser.
