How to Turn Multiple Photos into One PDF on iPhone

You’ve got five photos of a signed contract, or a dozen receipt photos, and you need them as one PDF, not five separate attachments. iOS has no built-in way to do this. Here’s the honest version: Grabio doesn’t combine multiple photos into one PDF in a single tap, no tool on iPhone genuinely does that on-device. What it does have is two tools that, used one after the other, get you there in a few minutes, still free, still no app to install.

Why This Takes Two Steps, Not One

Grabio’s Photo to PDF action converts one photo into one PDF at a time, that’s what Apple’s on-device Shortcuts actions actually support. To get five photos into a single multi-page PDF, you first turn each photo into its own PDF, then merge those separate PDFs into one file using Grabio’s Merge PDFs tool. Merge PDFs hands off to PDF24 (tools.pdf24.org) because no Shortcuts action can combine PDF files locally on iPhone, that part of the job runs on PDF24’s site, not on your phone.

How to Combine Multiple Photos into One PDF on iPhone with Grabio

1. Add Grabio to your iPhone once, it’s a free Apple Shortcut. Get the free Shortcut here.
2. Stage one, convert each photo. Open the first photo in Photos, tap Share, tap Grabio, choose Photo → PDF. It saves to Files. Repeat for every photo you want in the final document.
3. Stage two, merge the PDFs. Open one of the new PDFs in Files, tap Share, tap Grabio, and this time choose Merge PDFs from the PDF menu.
4. Grabio opens PDF24 in your browser with that first PDF already picked. Tap Choose Files on PDF24 and add the rest of the PDFs you just made, in the order you want them.
5. Tap Merge on PDF24. The combined, multi-page PDF downloads straight to your iPhone.

Is It Private and Free on iPhone?

The Photo to PDF step runs entirely on your iPhone using Apple’s own tools, nothing uploads. The merge step is the one exception in Grabio’s toolkit: it hands your files off to PDF24, a free, ad-light, well-known PDF site, because iOS has no on-device way to combine PDFs. Both stages stay free with no account, no login, and no cap from Grabio’s side.

Multiple Photos to One PDF: FAQ

Can Grabio do this in a single tap instead?

Not currently, and it wouldn’t be honest to claim otherwise. Apple’s Shortcuts actions convert one photo to one PDF, and merging requires a separate step that can’t run on-device. The two-stage process above is the real workflow.

Does the order of my photos matter?

Yes. When you add files on PDF24’s Choose Files screen, they usually merge in the order you add them, so convert and add your photos in the sequence you want the final pages to appear.

Is there a limit to how many photos I can combine?

No cap is set by Grabio. PDF24 handles as many individual PDFs as you add through its file picker, the practical limit is how many photos you’re willing to convert one at a time first.
