How to combine photos into a PDF on iPhone with Preview

Prepare the images as a small document

This workflow starts with image files that you can browse in Preview. If your pictures are only in Photos, use its share sheet to save copies to Files first, then find that location in Preview. Keep your originals in place.

Choose the intended sequence before building the PDF. For a small portfolio, you might use an overview, a close detail and a second view. For photographed paperwork, use the original page order. Rename working copies clearly enough that you can distinguish them in the file picker.

This is a document workflow, not an archival image format recommendation. Keep the separate source images if someone will need to edit, print or inspect them independently.

Make the first PDF page

Apple’s Preview documentation describes opening images through Browse or Recents. Open the image intended for page one. Use the actions menu beside the filename, choose Export, and select PDF. Then open the resulting PDF before adding pages.

The instructions here are scoped to Preview on iOS 26. If your software lacks that app or the controls differ, use Apple’s version selector in the linked guide instead of hunting for an identical menu in Photos.

Add and arrange the remaining pictures

1. In the PDF, tap the page count to reveal thumbnails. Apple notes that a pinch gesture can reveal the controls if needed.
2. Touch and hold a page thumbnail, choose Insert from File, and select the next image. Repeat for the pictures you want to include.
3. Inspect the thumbnails after each insertion. To change the sequence, hold a thumbnail until its menu appears, then drag it above or below another page.
4. If a page faces the wrong way, use the rotation controls in Preview. Keep all intended content visible and check the result at readable size.

Check what the recipient will actually receive

Close the document and reopen the saved PDF, rather than judging only the working view. Count the pages. Read the smallest useful detail on each one. Check that a landscape page has not made another page’s text too small for the intended reader.

Try this review on a three-photo example: page one should establish the subject, page two should show the detail you want discussed, and page three should add a different view. If pages two and three are indistinguishable at phone size, choose a tighter source crop or omit one. More pages do not automatically explain more.

Reduce size only after checking readability

Preview’s export dialog also offers a file-size adjustment. Use a separate export when trying a smaller file so you can compare the two versions. Stop reducing size once useful details begin to disappear.

Confirm that the receiving form accepts PDF and note its size limit. If it asks for separate JPEG images, a combined PDF will not satisfy that request. Before sharing, review every page for material you did not mean to include. Do not assume conversion makes sensitive information disappear.
