How to Convert Photos to PDF on iPhone
Last updated
Turning photos into a PDF on an iPhone is something people reach for constantly — a photographed contract, a stack of receipts for an expense claim, both sides of an ID for a form. The job is simple, but there's one iPhone-specific catch that causes most of the frustration: by default, your iPhone saves photos as HEIC, not JPG, and a lot of tools don't read HEIC.
This guide covers two reliable routes. The first uses the free Image to PDF tool in Safari, which works once your photos are in a supported format. The second uses the PDF Editor app, which reads HEIC straight from your camera roll and skips the format dance entirely.
Pick whichever fits the moment — but know the HEIC detail first, because it's the thing that turns a 30-second task into a confusing one.
Step by step
- 1
Decide your photo format
Open Settings → Camera → Formats. "High Efficiency" saves HEIC; "Most Compatible" saves JPG. Switching to Most Compatible makes new photos work everywhere, including browser tools.
- 2
Convert existing HEIC photos if needed
Already shot in HEIC? Either re-export them as JPG (open in Photos, share, choose a JPG-producing option) or skip straight to the app route below, which reads HEIC directly.

Open the Image to PDF tool in Safari
Go to the Image to PDF tool. It accepts JPG, PNG and WebP and runs entirely on your device — nothing is uploaded.
- 4
Add your photos and order them
Tap to choose photos from your library, then use the arrows to sequence them. Page order matters for multi-page documents like a two-page contract.
- 5
Create and save the PDF
Tap Create PDF. When it downloads, use the share icon to save it into the Files app or send it on directly.
- 6
Or use the PDF Editor app for HEIC and scanning
The app reads HEIC photos from your camera roll, turns them into a PDF, and can also capture fresh pages with edge detection — no format conversion required.
Tips
- The single biggest cause of "my photos won't convert" on iPhone is HEIC. Switch to Most Compatible, or use the app, and the problem disappears.
- Crop each photo in the Photos app before converting — the page is sized to the image, so trimming the background gives a tidier document.
- For receipts and IDs, shoot on a dark, flat surface in even light. Glare and shadows are harder to fix than to avoid.
- A photo turned into a PDF is not a searchable scan. If you need to search the text, use the app's scanning feature, which can recognise text.
- If the finished PDF is too big to email, run it through the Compress PDF tool — phone photos make heavy pages.
Try it on your phone
This whole workflow lives on your phone, which is exactly what the PDF Editor app is built for: HEIC straight from the camera roll, on-device conversion with nothing uploaded, plus scanning and signing in the same place. For anything you do more than once, it's the faster route.
