HEIF Image – The Ultimate Guide to High-Efficiency Image File Format

Last Updated on May 22, 2023 by Peter Wood

What is a HEIF image? There are more and more devices using HEIF file format, including iOS devices. As for efficiency image format is growing in importance as the amount of digital content available on the Internet continues to arise. The high-efficiency image file format, which is a file format aims to be as compact as possible without sacrificing the picture quality. To have a better understanding of how HEIF files vary from others, keep on reading this article.

Part 1: What is High Efficiency Image File Format

The Definition of HEIF File

A HEIF file is an image that has been compressed using the High Efficiency Image Format (HEIF). It might be a collection of still photographs, a burst of images, or a succession of images. HEIF files also include information about each picture, such as metadata.

Moreover, the Moving Picture Experts Group (MPEG) established HEIF as a standard for storing and exchanging photographs and image sequences.

Key Features of a HEIF File

The video data is compressed using the High Efficiency Video Coding (HEVC) standard and stored using the widely accepted ISO Base Media File Format (ISOBMFF). This file format is optimized for the storing of picture bursts and cinema graphs, as well as for usage in computational photography.

Additionally, it permits the storing of both lossy and lossless picture data. It is a more efficient and convenient method of distributing still photos, image collections, and associated information.

Technical Information of HEIF Format

HEIF specifies the storage of HEVC Intra pictures and HEVC image sequences with restricted inter-prediction.

In line with this, HEVC supports a wide variety of Chroma formats and sample fidelity levels up to lossless coding. So, it can be used for a wide variety of applications, ranging from today's consumer devices that typically store images at 8 bits per sample to high-end professional devices that require sample fidelity and dynamic range up to 16 bits per sample.

Furthermore, computational photography introduces a new class of use cases for the HEIF file format. Now, a collection of linked photographs may be saved in a single file together with information identifying the connections between the individual images.

Part 2: HEIF V.S. AVIF, Here are the Differences

The image compression codecs evolved from the video codecs AV1 and HEVC. HEIF and AVIF video codecs are used to compress and decompress multimedia data without sacrificing quality. Thus, striking a balance between quality and weight, ensuring that we have a product of high quality without taking up an excessive amount of space. This is particularly advantageous, which is why several streaming services, such as Netflix, have already placed bets on these systems.

The primary distinctions between the two are in terms of comprehension, compatibility, and freedom. The compression ratios of AV1 and HEVC file formats are different, with the first being more interesting if we wish to compress more.

For instance, using the AV1 format results in a movie that is around 10 GB in size with the same quality as an HEVC video but occupies 12.5 GB. This may seem like a little contrast, but it is significant in the case of platforms that contain hundreds of movies since the size will continue to grow.

How to Open and Convert HEIF Photos

Step 1: To preview the image's information or explore multi-layer HEIF files, double-click any HEIF file to open it in full-screen mode. It not only allows you to inspect all the HEIF photographs included inside a single HEIF file but also allows you to move to another photo using the slider.

Step 3: You may select the destination folder, the picture type, and even the image quality. If the HEIF file has several layers, it will convert into all of the photos included inside the HEIF file. To convert HEIF image file format to GIF, click the OK button.

How to Manage HEIF Files

Step 1: Enable the Rotate function in the left menu. It has three modes: left, right, and 180. If you are satisfied with the result, choose the Start Convert button to batch convert HEIF files.

Step 3: To add a watermark to the HEIFs, you can enter the text watermark to the HEIC photo, get the position, choose the fonts, tweak the color, adjust the angle, and more other parameters.

Step 4: Once you want to export the desired HEIC file, you can enable the Rename option to add a Prefix, Suffix, New Name, Start with, and even a Sample when renaming HEIF files in batch.

Part 4: FAQs about HEIF Images

1Is it necessary to shoot in HEIF?

Despite HEIF's benefits over JPEGs, experienced photographers should still shoot RAW files for subsequent conversion. But if you're shooting with an iPhone, HEIF provides quality and storage advantages over JPEGs and other formats.

2Why are my images in HEIF format rather than JPEG?

HEIF is often used as the default file format for picture capture and storage on Apple and Samsung devices. If you're transferring photographs, the device automatically converts them to JPEG before sending them to your friends' or family's Android phones.

3What is the difference between the HEIC and the HEIF?

What is HEIC files? HEIF is the standard's abbreviation for High Efficiency Image Format, whereas HEIC is Apple's preferred file extension. The phrases are essentially interchangeable since both are based on the High Efficiency Video Compression (HEVC) standard.

4Can I convert Canon HEIF to another file format?

Yes. WidsMob HEIC enables you to convert Canon HEIF or HIF files to another file format, including JPG, PNG, BMP, and more. Since the program is ever upgrading, you can always use it to convert most HEIC files to another file format.


How rapidly corporations switch from JPEG to HEIF as their default picture format will be fascinating to watch. As long as Apple is leading the charge, other firms will follow suit. JPEG and all other image formats will continue to exist alongside the new format. The popularity of picture file formats ultimately waned, but they didn't perish.
