How do I merge PDFs on iPhone for free?

Merging PDFs on iPhone in 2026 doesn't require any third-party apps. Apple added native PDF tools in iOS 17 and expanded them in iOS 26. Here are the three free methods.

Method 1: Files app native (fastest, iOS 17+)

• Open Files.
• Navigate to the folder containing your PDFs.
• Tap Select in the top-right.
• Tap each PDF you want to merge (in the order you want them combined).
• Tap the More button (three dots) at the bottom → Create PDF.
• A new merged PDF appears in the same folder. Rename it.

Limitation: order is based on selection sequence — there's no way to drag-rearrange before merging.

Method 2: Shortcuts app (more control, free)

The Shortcuts app has a "Combine PDFs" action that lets you select multiple files and choose order.

• Open Shortcuts → tap + to create a new shortcut.
• Add the action Get File (set to "iCloud Drive" or wherever your PDFs are).
• Add the action Combine PDFs.
• Add the action Save File to choose where to save the merged PDF.
• Tap the shortcut to run it. Select files in the order you want them.

Once created, the shortcut sits on your home screen for one-tap merging.

Method 3: Apple Books (with annotation support)

• Open Books → Library.
• Long-press the first PDF → Share → Print.
• In the Print preview, pinch-zoom out on the page thumbnail to expand it.
• Tap the share button → Save to Files.
• This converts the PDF; repeat for each one.
• Then use Method 1 to merge.

This is more useful for converting annotated PDFs into a merged final.

Method 4: Quick Look multi-select (iOS 18+)

• In Files, select multiple PDFs.
• Tap and hold to open Quick Look on all of them simultaneously.
• From Quick Look, tap the share button → Create PDF.

What about third-party apps?

There are dozens of "PDF merger" apps in the App Store, but most are:

• Free with ads + push notifications.
• Free trial that demands subscription after 3 uses.
• Free but upload your PDFs to the developer's server (privacy issue).

The built-in iOS tools handle 95% of merging needs without any of these trade-offs.

For frequent users:

If you merge PDFs often (legal, academic, real estate), a dedicated PDF organizer like Némos handles this plus OCR, search, and folder organization. Free tier covers basic merging; paid tier adds bulk operations.

One pro tip:

If you're scanning physical documents to combine into a single PDF, use Notes' built-in scanner (Notes → new note → camera icon → Scan Documents). It handles multi-page scanning natively, then you can share the result as a single PDF. No merging step needed.
