How to Convert HEIC and HEICS Files to PDF Without Losing Quality

I recently ran into a problem with an unsupported file format while organizing photos on my computer. And instead of seeing the usual .jpg or .png formats, I saw something unfamiliar, heics. If you have faced the same issue and are curious to know about heics and why converting them to PDF is often the best solution – especially if you want to share or archive them easily, I’ve got you covered. For converting heic file to PDF, I use UPDF, which makes the process super simple.

Let me guide you through what HEICS files are and how to open and convert them into PDF or other formats with UPDF, step by step. To move on, please click the button below to download.

Part 1. What are HEICS files?

HEIC is are special format adopted by Apple devices for storing images and videos for better efficiency. This format is a variation of HEIC, which stands for High Efficiency Image Coding. The “S” stands for sequence, which means a HEICS file contains multiple images bundled together in one container. It is a modern image format adopted by Apple as the default format for photos due to its efficiency and high image quality. You usually see HEICS files when you take live photos or burst shots. Instead of saving each frame as a separate file, your device stores them all together in one HEICS file.

Format	Number of Images	Use Case
HEIC	One image	Regular photos
HEICS	Multiple images	Live Photos, burst mode, animations

The HEIC/HEICS format not only saves the picture but also stores a lot of metadata, such as the image size or resolution.

For example, 4032 × 3024 pixels or 300 DPI(dots per inch).

It also stores image location, orientation and timestamps in metadata.

Part 2. How do I open a HEICS file?

HEICS files are a sequence of HEIC images and require compatible software to view them properly. If you are not using Apple devices, then you will need to convert .heics into another format or download the HEIF image extension.

On Mac:

On Apple devices such as Mac, iPhone or iPad, you can directly open .heics files due to its default format. Just click on the files and open them in a preview program. But

On Windows 10/11:

In Windows 10 or later, you will need to download the HEIF Image Extension tool from the Microsoft Store. Once installed, the window will convert .heic files, and you can preview them in the photo app.

You can also use an online converter, upload HEICS files and convert them into other formats to be suitable with your device.

On other devices: If you’re on Android or older systems, you may need third-party apps to open HEICS.

For converting HEICS to PDF, I highly recommend using UPDF. Just drag your HEICS files into UPDF and create high quality PDF in seconds.

Why Convert HEIC to PDF? (Optional)

HEICS files are great for saving space and keeping related images together, along with extra details in the form of metadata. But they are not always easy to open or share-especially if you are using a Windows PC or an Android phone. Many apps don’t support HEICS files, and even some websites won’t let you upload them.

That’s where converting comes in.

I often need to send photos to clients, attach them to documents, or archive them. And for that PDF is the best option. It’s universal, easy to open on any device, and perfect for organizing multiple images in one file. PDF can be annotated or edited, and is easy to print or share.
