Converting HEIC to PDF solves this problem, making your photos universally compatible.

In this guide, we'll show you several methods to convert HEIC images to PDF directly on your iPhone, from using built-in features to online tools.

Common Questions and Answers

Q: What if I need to convert many photos regularly?

A: For regular use, online tools are more efficient as they support batch processing. You can convert dozens of images in a single operation, saving significant time.

Best Practices and Tips

Choose the Right Method
- For single images: Built-in iPhone method works fine
- For multiple images: Use online tools for batch processing
- For advanced needs: Consider using a Mac if available
Optimize File Size
- If the resulting PDF is too large, use PDF compression tools
- Adjust quality settings based on your needs
- Consider the purpose: lower quality may be acceptable for document submissions
Organize Before Converting
- Select and organize your images before starting conversion
- Name your PDF files descriptively for easy identification
- Consider the order of images if creating a multi-page PDF
Check Requirements
- Verify the file size limits of the system you're submitting to
- Ensure the PDF format is accepted
- Check if there are specific page size requirements
Privacy Considerations
- Use tools that process files locally in your browser
- Avoid tools that require file uploads to unknown servers
- Read privacy policies if using third-party services

Troubleshooting

Issue: Print option not appearing in Share menu

Solution: Make sure you're viewing the photo in full screen, not in the grid view. The Print option appears when you tap Share from an individual photo.

Issue: PDF file is too large

Solution: Use PDF compression tools to reduce file size, or adjust quality settings during conversion to create a smaller file.

Issue: Multiple images not combining into one PDF

Solution: When using the built-in method, you need to convert each image separately. For multiple images, use online tools that support batch processing.

Issue: Images appear rotated incorrectly

Solution: Check the orientation settings in your conversion tool. Most tools allow you to choose between Portrait and Landscape orientations.
