2. Tap “Tools” at the bottom of the screen, then select “Merge files”.
3. Choose the photos that are already in your Lumin account, or tap “Add files” to upload photos directly from your phone.

Method 2: Use the Photos app’s hidden Print‑to‑PDF trick

You can convert pictures to PDFs directly from the Photos app without installing anything:

1. Open “Photos” and tap “Select” to pick the image(s) you want to convert.
2. Tap the “Share” icon and choose “Print”
3. In the Printer Options screen, pinch out on the thumbnail to open a PDF preview.
4. Tap the “Share” icon again and choose “Save to Files” to keep the PDF on your device or send it via Mail, AirDrop, etc. Selecting multiple photos combines them into a single PDF.

This method is ideal when you’re on the go and want a quick, offline way to convert photos to PDF.

Method 3: Use the Files app’s Quick Actions

If your pictures are in the Files app, or you’re happy to move them there, you can convert them with just a couple of taps:

1. Open “Files” and locate your image.
2. Long‑press the file and choose “Quick Actions” → “Create PDF”. A PDF version appears in the same folder.
3. To convert multiple images at once, tap “Select”, pick the images, then choose “More” (…) → “Create PDF”.

This approach keeps the original dimensions of your picture and works perfectly for documents stored in iCloud Drive or other cloud services.

Method 4: Convert and save with the Books app

The Books app isn’t just for e‑books. You can use it to convert photos to PDFs and store them neatly on your device:

1. In Photos, select the images you want to convert.
2. Tap “Share”, swipe along the app list, and choose “Books”. Your images are instantly converted into a PDF and saved in the Books library.
3. To export the PDF, open Books, tap the “More (…)” button under the document, and choose “Share PDF”.

Books is great for organizing PDFs and making quick annotations, particularly for study materials or long documents.

Method 5: Scan paper documents with the Notes app

When you need to digitise a paper receipt or document, the Notes app’s scanning function creates clean, PDF‑quality scans:

1. Open a new note in Notes and tap the “Attachment” or “Camera” icon → “Scan Documents”.
2. Hold your iPhone over the paper; Notes automatically detects edges, straightens the scan and enhances contrast.
3. Save the scanned pages and tap the “Share” button → “Save to Files” to store the document as a PDF.
