How to Turn Photos Into a PDF on iPhone or Android

By the PdfToolbox team · June 11, 2026

A landlord wants “the signed form as a PDF”, a professor wants homework “as one PDF, not nine photos”. Your phone has the photos; here’s how to get the PDF — including the built-in ways most people never find.

On iPhone: the hidden print trick

  1. Open Photos and select the photo(s).
  2. Tap Share → Print.
  3. On the print preview, pinch outward on the page thumbnail — it silently turns into a PDF.
  4. Share or save that PDF from the preview screen.

It works, but it’s well hidden, gives you no control over page order, and the file is often enormous because the full-resolution photos go in untouched.

On Android: print to PDF

  1. Open the photo in Google Photos.
  2. Tap ⋮ → Print.
  3. Choose Save as PDF as the printer and hit the download button.

Same caveats — one photo at a time on many versions, no reordering, big files.

On both: do it in the browser

For several photos in a specific order, open JPG to PDF in your phone’s browser: add the photos, drag them into order, and download a single PDF with one image per page. PNG screenshots work the same way via PNG to PDF.

Two phone-specific tips:

  • iPhone saves HEIC, not JPG. If a photo won’t load, go to Settings → Camera → Formats → Most Compatible, or share the photo to Files first — iOS converts it to JPG on the way out.
  • Mind the size. A few camera photos make a 20 MB PDF easily. If it’s headed for an email or an upload form, run the result through Compress PDF for email right after.

Why the browser method is also the private one

Photos of forms, IDs and signatures are exactly the things you don’t want sitting on a conversion site’s server. The tools above run in your browser — the photos never leave your phone, which matters when the photo is the document.
