💡

A common scenario

You have three PDF receipts saved to the Files app on your iPhone and need to email them as one attachment instead of three.

🔒

Why privacy matters here

Free iPhone PDF apps often upload to a server or require a subscription. DukPdf keeps the merge inside the browser tab on your iPhone, so the receipts never leave the device.

Merge PDF on iPhone — questions

Can I merge PDFs on iPhone without downloading an app?

Yes. DukPdf runs in Safari, Chrome, and any modern mobile browser on iOS. Open the Merge PDF page, choose files from the Files picker, and download the combined PDF.

Where do the merged files save on iPhone?

After you tap download, iOS offers to save the file to the Files app or share it via Mail, Messages, AirDrop, or any other app that accepts PDFs.

Can I reorder pages on a small screen?

Yes. Pages appear as large touch-friendly thumbnails. Tap and hold a thumbnail to start dragging, then drop it in the new position. The interface is designed for touch.

Are the files uploaded anywhere?

No. The merge runs locally in the browser tab. You can confirm by opening a desktop-class browser inspector view, or simply by checking that you do not need an internet connection once the page has loaded.
