The term “Joint Photographic Experts Group - Extra Large,” or simply “JPEG-XL,” refers to a modern image compression format and codec developed by the JPEG Committee (Joint Photographic Experts Group). When compared to established picture formats like JPEG (Joint Photographic Experts Group), JPEG-XL’s main goal is to give enhanced image compression efficiency and quality. It aims to offer a wide range of features and functionalities at the same time.
On the other hand, the term “AV1 Image File Format,” abbreviated as “AVIF,” refers to a modern image compression format and codec that is based on AV1 video codec technology. Its main goal is to offer improved image compression quality and efficiency in comparison to existing image formats while incorporating a wide range of features and functions.
In general, AVIF can be the best choice if your main objective is to get the maximum compression while maintaining outstanding image quality. On the other hand, JPEG XL is a flexible option if you require a format that delivers a well-rounded solution, accommodating both lossless and lossy compression, and catering to a wide range of applications.
Gumlet became the first cloud provider to provide automatic support for the JPEG XL format.
Here’s a detailed comparison between these two formats:
JPEG XL uses a flexible and effective compression method that allows for larger compression ratios without sacrificing image quality. It can be used for a variety of applications because it supports both lossless and lossy compression.
AVIF (AV1 Image File Format) is a video codec that was derived from AV1 and is renowned for its remarkable compression performance, particularly in high-quality and lossless modes. When compared to JPEG XL, AVIF frequently produces lesser file sizes for some types of photos.
Created to produce high-quality photos with a minimum amount of artifacts, even at harsh compression levels, JPEG XL makes use of cutting-edge technologies like Variable Quantization to adaptively allocate bits to various areas of the image in order to preserve important information.
AVIF, especially in lossless and high-quality settings, excels at keeping image quality. When compared to more traditional formats like JPEG, it benefits from the superior compression methods of the AV1 video codec, producing images with fewer compression artifacts.
JPEG XL support in browsers was minimal but steadily growing as of my most recent update in September 2021. There were third-party libraries available to improve compatibility, and some browsers, like Chrome, offered experimental support.
In 2021, AVIF encountered similar difficulties with browser support but was making progress. It’s vital to check the most recent browser compatibility for both formats as of 2023 because both were relatively new.
JPEG XL offers a number of characteristics, such as lossless compression, visibility (alpha channels), animation, and progressive rendering. It is suitable for a variety of image kinds because of its adaptability.
AVIF also enables animation, transparency, and lossless compression. Its compatibility with the AV1 video codec and several of its capabilities make it an excellent choice for high-quality and high-resolution photos.
Depending on the individual implementation, JPEG XL encoding and decoding times can vary. In general, it offers enough performance for the majority of use scenarios.
In particular for high-quality and lossless versions, AVIF encoding and decoding can be computationally demanding. However, software and hardware optimizations keep becoming better over time.
In conclusion, which format is better depends upon your needs and requirements. As we discussed above, JPEG XL is a good choice if you place a focus on adaptability and finding a satisfying balance between compression effectiveness and image quality. On the other hand, AVIF might be a better option if your main requirement is for the best compression efficiency, particularly for top-quality photographs.
