FAQ
Is dedupe case-sensitive?
You can choose. Case-sensitive mode treats ‘Apple’ and ‘apple’ as different; case-insensitive collapses them.
Can I keep the original order?
Yes - sorting is optional, so you can dedupe while preserving the order lines first appeared.
Is Sort & Dedupe free?
Yes. Every tool on docsntools is 100% free with no signup, no watermarks, and no upload limits.
Are my files uploaded to a server?
No. All processing happens entirely in your browser. Your files never leave your device.
Does it work on mobile?
Yes - every tool is responsive and works in modern mobile browsers (Chrome, Safari, Firefox).
