Remove Duplicate Lines on iPhone
How Remove Duplicate Lines runs in mobile Safari — works offline once loaded. Browser-based, free, no signup, runs entirely on your device.
One reason people install third-party apps on their phone is that they don't realise the same tool runs perfectly in mobile browsers. Remove Duplicate Lines is browser-only — no app store, no install — and it works exactly the same on iPhone as it does on a laptop.
Launch the tool: Remove Duplicate Lines — Browser-only. Nothing is sent to a server.
Step-by-step on iPhone
- Open Safari and go to Remove Duplicate Lines.
- Tap "Choose file" (or drag from the Files app if you're in split-screen on iPad).
- Pick the text from Photos, iCloud Drive, or Files — they all work.
- Set your options (sizes, quality, output format). Tap "Run" or whatever the equivalent button is for Remove Duplicate Lines.
- Save the result. Safari downloads to the iCloud Drive Downloads folder by default; tap the result and choose "Save to Files" if you need it somewhere specific.
- AirDrop or share it straight from the Files share menu — useful if the text is going to a Mac next.
Useful iOS-specific tricks
- Add Remove Duplicate Lines to your home screen to make it feel like a native app: tap the share button in Safari, scroll to "Add to Home Screen." It launches in its own window, no browser chrome.
- Use the Files app for batch input — select multiple texts in Files, tap Share → Open in Safari, and Remove Duplicate Lines picks them all up at once.
- Photos library access works the same as any iOS app, but with no permissions to grant separately.

Browser-only. Nothing is sent to a server.
Why a browser tool beats most native apps for this
Native apps that work with texts are almost all just wrappers around browser-class libraries. They usually upload your file to their server, which is slower, less private, and sometimes paywalled. Remove Duplicate Lines does the work directly in your phone's browser engine — same code path that would run if you were on a desktop, no upload, no signup, no daily limit.
Frequently asked questions
Does it work on older iPhones?
Anything from the last five years handles Remove Duplicate Lines comfortably. Older devices may take longer for big files, but the underlying APIs (WebAssembly, FileReader) have been stable for years.
Can Remove Duplicate Lines access my iCloud Photos?
Only when you pick a file through the standard system file-picker. The browser sandbox prevents any app — including Remove Duplicate Lines — from reading your library without an explicit selection.
Is my text private when I use a browser tool?
Yes — more private than most apps, because nothing is uploaded. The text is processed entirely inside the browser tab and is gone the moment you close it.
Why isn't there a "Remove Duplicate Lines" app on the App Store?
Because there doesn't need to be. Mobile browsers run the same WebAssembly the desktop site uses. Shipping a native app would mean maintaining two codebases for the same feature.
