Converting multiple images to a single PDF on iPhone is a common task — combining photos of a document, creating a photo album PDF, or collating receipts into one file. iOS makes this possible through a few different routes, and no extra app is required for the most common scenarios.
How to Convert Multiple Photos to PDF Using the Files App
The Files app on iOS 16 and later can create a PDF from multiple images directly. First, save all your images to a folder in the Files app (or iCloud Drive). Open that folder, tap the three-dot menu in the top-right corner, and select Select. Tap each image you want to include, then tap the three-dot menu again and choose Create PDF. iOS combines the selected images into a single PDF in the same folder, one image per page.
The order of pages in the PDF follows the order you selected the images. If you want a specific sequence, tap the images in that order rather than using Select All.
Converting Photos to PDF From the Photos App
From the Photos app, tap Select in the top-right corner and choose all the images you want. Tap the Share button, then scroll down and tap Print. In the print preview, pinch outward on the preview thumbnail with two fingers to convert it to a PDF view. Tap the Share icon in the top-right corner and select Save to Files to save the combined PDF.
This print-to-PDF method works on any iOS version and doesn't require the files to be in the Files app first. The images appear in the same order they were selected in the Photos grid.
Using an Online Tool for More Control
For more flexibility over page order, image scaling, and page size, use WukongPDF's Image to PDF tool in Safari. Open the tool, tap to upload multiple images at once, drag the thumbnails to set the order, and tap Convert. Download the finished PDF to Files.
The online tool also lets you mix image types in one PDF — JPEG photos alongside PNG screenshots, for example — and handles the file without requiring any app installation. It's particularly useful when you're combining images from different sources rather than a single camera roll selection.
Controlling Page Size and Image Layout
The Files app method and the print-to-PDF method both scale each image to fill the page, which usually looks fine for photos but may add white space around portrait images placed on a landscape page or vice versa. If consistent page sizing matters — for a professional document or client-facing report — the Image to PDF tool gives you options to fit, fill, or center each image.
For scanned documents where you want the images to appear at their actual captured size without scaling, choose the fit option rather than fill — this prevents the tool from stretching smaller images to fill the page unnaturally.
Reducing the Size of the Combined PDF
A PDF made from multiple photos can be large — phone camera images are often 3–5 MB each, so a 10-photo PDF might start at 30–50 MB. If you need to share it by email or upload it somewhere with a file size limit, run it through a PDF Compression tool to bring the size down. Most photo-based PDFs compress well without visible quality loss at normal viewing sizes.
