How to Convert Image to PDF on iPhone: Complete 2025 Guide

Why Convert Images to PDF on iPhone?

Before diving into the methods, let's understand why you might want to convert images to PDF format on your iPhone:

• Professional Documents: PDFs are the standard format for official documents, making them perfect for contracts, invoices, and reports
• Easy Sharing: A single PDF file is much easier to share than multiple image files via email or messaging apps
• Universal Compatibility: PDF files can be opened on any device without quality loss or formatting issues
• Reduced File Size: Combining multiple images into one PDF often results in a smaller overall file size
• Better Organization: Keep related images together in a single, searchable document

Method 1: Using the Files App (Built-in iOS Feature)

The Files app is the quickest and most straightforward method to convert images to PDF on iPhone. Here's how:

1. Open the Photos app on your iPhone and select the image(s) you want to convert
2. Tap the Share button (the square with an arrow pointing up) at the bottom left
3. Scroll down and tap "Save to Files"
4. Before saving, tap on "Options" at the top of the screen
5. Change the format from "Automatic" to "PDF"
6. Choose your save location (iCloud Drive or On My iPhone) and tap "Save"

Pro Tip: You can select multiple images at once in the Photos app by tapping "Select" and choosing all the images you want to include in your PDF. They'll all be combined into a single multi-page PDF document.

Method 2: Using the Print to PDF Feature

This hidden iOS feature lets you create PDFs from almost any app that has a print function:

1. Open the image in the Photos app
2. Tap the Share button and select "Print"
3. Use the pinch gesture (place two fingers on the preview and spread them apart) to zoom in on the print preview
4. Tap the Share button in the top right corner
5. Save the PDF to Files, or share it directly via email, Messages, or other apps

Method 3: Using iOS Shortcuts App

For frequent conversions, creating a Shortcut can save you time:

1. Open the Shortcuts app (pre-installed on iOS 13 and later)
2. Tap the "+" button to create a new shortcut
3. Add the "Select Photos" action from the library
4. Add "Convert Image" action and set the format to PDF
5. Add "Save File" action to choose where to save your PDF
6. Give your shortcut a name like "Image to PDF" and save it

Now you can run this shortcut anytime from the Shortcuts app or add it to your Home Screen for even quicker access.

Method 4: Using the Markup Tool

The Markup tool provides more control over your images before converting:

1. Open your image in the Photos app
2. Tap "Edit" in the top right corner
3. Tap the Markup icon (circle with a pen tip)
4. Make any edits you want (annotations, signatures, highlights)
5. Tap "Done" and then use Method 1 or 2 to convert to PDF

Method 5: Using Third-Party Apps

While iOS built-in features are sufficient for most users, some third-party apps offer additional features:

• Adobe Acrobat Reader: Professional PDF creation with advanced editing features
• PDF Expert: Powerful PDF editor with cloud storage integration
• Scanner Pro: Combines document scanning with PDF conversion
• ToJPG (Web-based): Free online converter accessible from Safari without app installation
