Frequently Asked Questions

Is my text uploaded to a server?

No. ZippyEdit processes everything locally in your web browser using JavaScript. Your text never leaves your device, making it completely private and secure for sensitive data.

How does it handle case sensitivity?

By default, the tool treats "Hello" and "hello" as different lines (case-sensitive). You can toggle case-insensitive mode to treat them as duplicates and keep only one.

Does it preserve the original order of lines?

Yes! The duplicate remover keeps lines in their original order. When duplicates are found, the first occurrence is kept and subsequent duplicates are removed.

Is there a limit on how much text I can process?

There are no artificial limits. Since processing happens in your browser, you can handle large amounts of text limited only by your device's memory.
