Why we built it
The web is full of PDF mergers that ask you to upload your contracts, medical records, and tax returns to a server you'll never see. PDF Merge does the whole job on your phone.
A private utility for people who read the fine print.
Features
Everything the online tools do — without the internet.
Built with Apple's native PDFKit. No third-party libraries, no analytics SDKs, no network calls.
Cherry-pick pages
Switch to the Pages tab and select individual pages from any of your source files. Assemble the exact document you need.
Rotate and reorder
Fix upside-down scans in a single tap. Drag pages into place with fluid, native drag-and-drop.
Built for big files
Tested with PDFs of a thousand pages and more. Nothing to upload, nothing to wait on.
Save, share, send
Export straight to Files, iCloud Drive, Mail, WhatsApp, or any share sheet destination. Rename before you send.
Recent library
Every merge stays one tap away in a Recents view. Preview, rename, or reshare without repeating the whole flow.
Screens
From empty state to finished file.
Five taps between opening the app and having a merged PDF in your Files.
Three steps
The whole workflow.
No account. No cloud sync. Nothing to configure.
01 · Import
Pick your PDFs.
Tap Select PDFs and choose files from Files, iCloud, or a share sheet. Import as many as you like.
02 · Arrange
Reorder, rotate, remove.
Switch between Files and Pages views to organize either whole documents or individual pages exactly how you want them.
03 · Export
Save or share.
Tap Merge, name the result, and send it wherever it needs to go. Every merge is saved to your Recents.

Common questions
Everything else.
Still stuck? Get in touch — we answer every message personally.
Do my PDFs really never leave my phone?
Yes. PDF Merge uses Apple's PDFKit framework to process files locally. The app makes no network calls, has no analytics SDK, and doesn't require an account. You can verify this yourself by putting your phone in airplane mode — the whole app still works.
Is there a page or file-size limit?
No hard limit. The only ceiling is your device's available memory. We've tested with individual PDFs of a thousand pages and merges of a few thousand pages combined without issues on modern iPhones.
What's the difference between the free and Pro versions?
Everyone gets every feature — all the page-editing tools, the Recents library, unlimited imports. Free is limited to merging two PDFs at a time. Pro removes that cap.
Can I cancel Pro?
Anytime, directly from your iPhone's Settings → Apple ID → Subscriptions. The Yearly plan starts with a 3-day free trial you can cancel before being charged. Lifetime is a one-time purchase with no ongoing charge.
Do you sell my data?
No. There is no data to sell. The app doesn't collect it. Our full privacy policy is here.
Which iPhones does it support?
Any iPhone running iOS 17 or later. iPad support is on the roadmap.
Merge PDFs privately.
Free to try. Two taps to your first merged PDF. Nothing to sign up for.
