Today, we will discuss a next-gen AVIF Image Format in this blog which is the rising star in the world of image formats, poised to revolutionize the way we compress and display images on the web. It is by far a superior format in terms of compression we have seen so far!

What is AVIF?

AVIF, stands for AV1 Image File Format is a Next-gen Image Format as ascribed by Google Web Core Vitals. Launched in September 2018 after the wild success of its video codec, AV1 Image File Format (AVIF) is an encoding based on the open-source AV1 video codec which began in 2015 as a collaborative effort between several industry-leading technology companies, including Google, Mozilla, Cisco, and Netflix which later formed an alliance along with some other contributors called Alliance for Open Media (AOM). The AV1 codec was officially released in March 2018.

AVIF is even newer than Google's WebP Format in terms of the historical evolution of image formats. AVIF is developed to address every possible use case for raster images on the web: GIF-like animation, PNG-like transparency, and improved perceptual quality at file sizes smaller than JPEG or WebP.

What is the full form of AVIF?

The acronym AVIF stands for "AV1 Image File Format". Let's break down what this means:

The AV1 Video Codec: AVIF is closely tied to the AV1 video codec. AV1 was developed by the Alliance for Open Media (AOMedia), emerged as a cutting-edge, open-source, royalty-free video compression standard designed to deliver high-quality video at lower bitrates. AV1 was designed to outperform its predecessors (like VP9 and H.264) in terms of compression efficiency and gained rapid adoption for online video streaming platforms, such as YouTube and Netflix.

The Birth of AVIF: Building on the success of AV1 for video, the developers saw the potential to extend this technology to still images. Thus, AVIF Image File Format was born. A testing framework developed by Netflix shows significant compression in file sizes when compared to JPEG or WebP maintaining better image quality.

What are the Key Features and Advantages of AVIF?

Superior Compression: AVIF offers remarkable compression efficiency, often outperforming other popular image formats like JPEG, PNG, and WebP. With AVIF, users have seen file sizes drop by nearly 60% compared to JPEG and 35% compared to WebP, with no loss in image quality.

How does AVIF Compression Work?

Let's delve into the inner workings of AVIF compression:

A. Leveraging the AV1 Video Codec

At the heart of AVIF is the AV1 video codec, a highly efficient and open-source codec developed by the Alliance for Open Media (AOMedia). While originally it was designed for video compression, AV1's techniques are leveraged for still image compression in AVIF.

B. Intra-Frame and Inter-Frame Compression in AVIF Format

AVIF employs a combination of intra-frame and inter-frame compression techniques:

Intra-Frame Compression: Intra-frame compression works similarly to traditional image formats like JPEG. It compresses individual frames or images without reference to other frames. AVIF uses this method for lossless compression and for the first frame in animations.

Inter-Frame Compression: This technique is borrowed from video compression and is particularly powerful for photos in AVIF. It compresses subsequent frames by referencing the preceding frames, allowing for greater compression efficiency. It's particularly effective for animations, where many frames share similarities.

C. Compression Settings and Trade-offs with AVIF Format

When working with AVIF, you'll encounter compression settings that allow you to balance file size and image quality:

Quality Levels: AVIF often offers a quality setting where you can specify the desired quality level. Higher quality levels result in larger files with better image quality, while lower levels prioritize smaller file sizes.

Lossless vs. Lossy Compression: AVIF supports both lossless and lossy compression. Lossless compression retains all image information but may result in larger file sizes. Lossy compression sacrifices some image detail for smaller files.

Chroma Subsampling: AVIF also allows you to control chroma subsampling, which affects the color information in the image. Subsampling can further reduce file size, but it may result in some color artifacts.

AVIF File Format: Structure and Components

The AVIF format utilizes the ISO Base Media File Format (BMFF) developed by the International Organization for Standardization (ISO). BMFF serves as a flexible container format capable of accommodating diverse media data types like video, audio, and images. As a result, AVIF files adopt a similar structure to other BMFF-based formats including MP4 and ISOBMFF.

AVIF Boxes

In terms of organization within an AVIF file, it follows a hierarchical arrangement composed of nested containers known as boxes. The foremost box at the top level is referred to as the File Type Box (ftyp). It serves two purposes: identifying the file as an AVIF format while also specifying which version of this particular format is being employed. Within this ftyp box, several other boxes can be found, housing the actual image data and various metadata components. These include the Media Data Box (mdat), Item Location Box (iloc), and Item Properties Box (iprp).

Image Data

Regarding the image data itself, an AVIF file stores it as a sequence of compressed frames encoded using the AV1 codec. Each frame is contained within its individual box named the Compressed Image Item Box (ispe). Accompanying each frame is a decoder configuration record that imparts specific encoding parameter information relevant to that particular frame. The modular structure allows AVIF files to store multiple images within a single file, varying from a series of thumbnails to diverse resolutions of identical images.


AVIF files go beyond just storing compressed image data; they also have the ability to hold various forms of metadata like Exif, XMP, and ICC profiles that provide extra details about the image and how it was created. To ensure efficient management, these AVIF files neatly organize this metadata into dedicated boxes that can be accessed and modified independently from the actual image data itself.

What are the Use Cases of AVIF Format?

Here are some practical considerations for working with AVIF:

A. Creating AVIF Images from Existing Images

Conversion Tools: To create AVIF images, you can use various conversion tools and software like Front.Space. It allows you to convert images from other formats like AVIF to JPG, AVIF to PNG, or AVIF to WebP on the fly.

Quality Settings: Most AVIF converters offer adjustable quality settings, allowing you to find the right balance between file size and image quality for your specific use case.

B. Integration of AVIF into Web Development and Design

HTML and CSS: To include AVIF images in your web pages, use the <img> tag and specify the AVIF image file in the src attribute. Consider using the <picture> element for responsive images, providing multiple formats (e.g., AVIF and JPEG) and letting the browser choose the most suitable one.

Lazy Loading: Lazy loading ensures that images are loaded only when they become visible in the user's viewport, reducing initial page load times.

Fallback Images: While AVIF offers superior compression, ensure that you provide fallback images in widely supported formats like JPEG or WebP for browsers that do not yet support AVIF. This ensures a consistent user experience across all devices and browsers.

Using Front.Space's automated API: It can be a cumbersome process to create, manage, and serve different formats of images for different purposes.
