If you own an iPhone or any Apple device, your photos are saved in HEIF format. It has been years since Apple implemented HEIF as the default image format for Apple Photos, given the quality and compression efficiency. But the sharing or use of such images can hit compatibility issues outside of the Apple ecosystem. One way to fix it right away is to convert HEIF to PDF — PDF is one of the most widely supported formats for sharing, printing, and archiving documents and images.
Converting HEIF to PDF is useful in many situations. It helps when printing photos, sharing files with clients, or submitting images through online forms. This guide explains what HEIF is and how it compares to PDF. You will also learn how to convert HEIF images to PDF on Windows and iPhone using free online tools.
What Is HEIF?
HEIF stands for High Efficiency Image File Format. This image file format was developed by the Moving Picture Experts Group (MPEG). HEIF was adopted by both iOS 11 and macOS High Sierra as the default image capture format and is already being used by other manufacturers as well, including some Android phone brands.
The biggest advantage of using the HEIF file format lies in its compression efficiency. HEIF images maintain excellent quality. They also require much less storage space than JPG files. HEIF files are much smaller than JPG files. This allows you to store more photos on your device without sacrificing quality. In addition, HEIF supports 16-bit color depth, transparency, frame sequences, and additional information, such as depth maps and HDR.
Unfortunately, the issue of HEIF’s low popularity should be mentioned. Most platforms won’t open HEIF files, and neither does Windows, nor a great number of other programs that work with images. Because of this, many people have to convert their HEIF images to PDF or JPG.
HEIF vs PDF: What are the Differences?
HEIF and PDF serve entirely different purposes, which is part of why conversion between them is so commonly needed.
| Feature | EPS | |
|---|---|---|
| Full Name | Encapsulated PostScript | Portable Document Format |
| Primary Purpose | Professional printing and graphic design | Document sharing, viewing, and printing |
| File Type | Primarily a vector graphics format | A document format that can contain text, images, and vector graphics |
| Scalability | Can be resized without losing quality | Can preserve vector quality and scale without loss when vector elements are used |
| Browser Support | Generally not supported by web browsers | Widely supported by browsers and PDF viewers |
| Ease of Sharing | Limited due to compatibility issues | Easy to share and open on most devices |
| Editing | Typically edited in professional design software | Can be viewed by most users and edited with PDF tools |
| Printing | Designed for commercial printing workflows | Suitable for both everyday and professional printing |
| File Content | Mainly graphics and illustrations | Supports text, images, graphics, forms, and multiple pages |
| Multi-Page Support | No, usually single-page artwork | Yes, supports multiple pages in one file |
| Security Features | No built-in security options | Can include passwords, permissions, and encryption |
| Compatibility | Best suited for design and print software | Compatible with almost all devices and operating systems |
| Common Uses | Logos, illustrations, billboards, packaging, print designs | Reports, contracts, manuals, presentations, and printable documents |
The completeness of compatibility is the key element that arises from this comparison. PDF files work on almost every device. They open on Windows, macOS, Android, iPhone, and Linux using standard PDF readers. HEIF, however, does need certain software or codecs to be installed on non-Apple devices. The HEIF-to-PDF converter resolves many compatibility issues. It makes sharing, printing, and submitting photos much easier.
Why Convert HEIF to PDF?
There are a number of use cases where converting a HEIF image to PDF is a better option than converting to JPG or another image format.
Universal Sharing and Compatibility
PDF is supported by almost all platforms, devices, and applications. A HEIF file sent to anyone with a Windows PC or an Android device might not be readable at all. A PDF will open immediately on any device; however, there is no need to have any special codecs or software installed. This is one reason many people learn how to convert HEIF to PDF. It makes sharing photos outside the Apple ecosystem much easier.
Professional and Official Submissions
Documents in PDF format are particularly required for many government forms, job applications, official websites, and professional websites. The PDF format can be used for HEIF images, so they will be accepted and will display properly on any computer the recipient uses.
Multi-Image Documents
PDF’s strength is that it allows you to merge several pictures into one single, organized document. Having multiple HEIF photos, such as scanned receipts, a set of property photographs, or a set of event photos, as a single PDF bundles the information together and makes it easier to distribute. This is not possible in a simple image format such as JPG.
Printing
Both professional and home printing use the PDF format. PDF is the native file format of most printers, print shops, and document management systems. When printing, you can print out an HEIF image as a PDF first to verify prints will be the correct size, correct margins, and print quality on different printers and operating systems.
Archiving
One of the most popular long-term formats for archiving documents and images is PDF. PDF is an ISO standard since 2008, a format that will stay supported over time, unlike most proprietary image formats.

Frequently Asked Questions
1. Can Windows open HEIF files?
By default, Windows doesn’t support HEIF. The HEIF Image Extensions that are available in the Microsoft Store are required to open .heif or .heic files directly. The easiest solution is to convert HEIF to PDF or JPG first with a free online converter such as AhaConvert, but it doesn’t require any software installation.
2. What is the difference between HEIF and HEIC?
HEIF is the general open image format; HEIC is Apple’s proprietary HEIF format. HEIC is a video compression standard based on HEVC (H.265) and has the .heic file extension. All HEIC files are technically HEIF files, but not all HEIF files are HEIC. Both formats have similar practical effects and are both converted with the same tools.
3. Why are my iPhone photos in HEIF format?
Since iOS 11, Apple has implemented HEIF, with HEIC becoming the standard photo file format. This is because of storage efficiency. HEIC photos are about 50% smaller than comparable JPG photos, yet can offer equivalent or better image quality. This will allow iPhones to hold many more photos without having to upgrade their storage.
4. Can I convert multiple HEIF images into one PDF?
Yes. AhaConvert has a batch upload feature, so you can upload multiple HEIF files in a single session and convert them all in one go. There are also tools available that can perform this function, such as iLovePDF, which can merge multiple images into a single PDF. This is especially helpful if you have multiple iPhone photos that you want to combine into a single shareable document or print.
5. Is this HEIF-to-PDF converter free?
Yes. There are no hidden fees or subscription plans, and no account registration is required to use AhaConvert. Just open the converter in your browser, upload your HEIF file, and download the PDF output. The tool supports unlimited conversions and can be used on any device with an Internet connection, free of charge.
6. Does converting HEIF to PDF reduce image quality?
AhaConvert is a high-quality converter that preserves image quality throughout the conversion process. PDF preserves the image at its original resolution, so the output PDF will be of very high image quality, matching the source HEIF file. A quality loss in conversion is minimal when the conversion is performed by a reputable converter and no unnecessary resampling or compression is used.
In Conclusion
While a great format for efficiently storing high-quality iPhone photos, AhaConvert HEIF to PDF Converter is not compatible with most other platforms and situations, making it unsuitable for sharing, printing, or submitting photos in most professional or cross-platform scenarios. There’s an answer to that HEIF-to-PDF problem. PDF is easily viewed on any device, is required by official forms and platforms, and is the default format used for professional printing and archiving.
You can use the AhaConvert HEIF to PDF Converter to convert images directly on your iPhone or on a Windows PC without installing any software. The AhaConvert image converter is a useful tool for those who want to convert HEIF to other image formats, as it supports a wide range of output formats, including JPG, PNG, etc. The next time you’re looking to share or print an iPhone shot, a quick HEIF-to-PDF conversion is all you need.
