Why convert images to PDF?

Converting images in PDF format offers several advantages. Let’s review why you might want to turn your iPhone photos into one of the most popular file formats on the web.

  • Universal compatibility: PDFs are universally supported on all devices and platforms, meaning anyone can open and view your files without needing proprietary software.

  • Document preservation: unlike regular image files, which may lose quality or change appearance when shared, PDFs maintain the original formatting, fonts, and layout to ensure they look their absolute best.

  • Security and encryption: PDFs allow you to add password protection and strong encryption, which can come in handy if your iPhone images contain personal or confidential information like identification card numbers or medical records.

  • Easy sharing: PDFs are often compact, making them the preferred choice when sharing multiple image files over email, messaging apps, or cloud storage services.

How to convert picture to PDF on iPhone using the Photos app

All Apple devices come preloaded with the handy Files app, allowing all users to convert iPhone photos to PDF without using third-party solutions. However, to benefit from free conversions, you first need to change how your iPhone stores your photos.

By default, all iPhones store images in the HEIC format, while the Files app method works only with JPEGs. To save your photos as JPEG, you need to:

  1. Open the Settings app.

  2. Tap Camera Formats.

  3. Tap Most Compatible.

Tap "Most Compatible" to set default image format as JPEG.

This will save all your subsequent photos as JPEG by default. Next, launch the Photos app and:

1. Open the image you want to convert.

2. Tap Share in the bottom left corner.

Tap "Share" to start converting your image to PDF.

3. Tap Save to Files.

Tap "Save to Files" to transfer your image to the Files app.

4. Open the Files app and find the image.

5. Long-press on the image and tap Quick ActionsCreate PDF.

From the Files app, tap "Create PDF" to automatically convert your JPEG into a PDF.

6. Your new PDF will be automatically created within the Files app.

If you want to save time and enjoy the same high quality, you can also use a solution like MobiPDF. To take advantage of the faster conversion method:

1. Launch MobiPDF on your device.

2. Go to Tools Image to PDF.

In MobiPDF, tap "More" > "Image to PDF" to convert your image.

How to convert multiple images using the Files app

1. Open the Files app.

2. Tap More Select to enter selection mode.

From the Files app, choose "Select" and long-press a file to create a PDF.

3. Choose the files that you want to convert to PDF.
