What is JPG4? JPG4, or JPEG XL, is a new image format that was developed by the Joint Photographic Experts Group (JPEG). It is designed to replace the older JPEG format, which has been in use for over 25 years. JPG4 offers a number of advantages over JPEG, including improved image quality, smaller file sizes, and support for a wider range of color spaces.
JPG4 is a lossy image format, which means that some of the original image data is lost when the image is compressed. However, JPG4 uses a more advanced compression algorithm than JPEG, which results in less visible artifacts and a higher overall image quality. In addition, JPG4 supports a wider range of color spaces, including the Rec. 2020 color space, which is used in HDR (high dynamic range) images.
JPG4 is still a relatively new format, but it is quickly gaining popularity. It is already supported by a number of software applications, including Adobe Photoshop and Google Chrome. As more software applications add support for JPG4, it is likely to become the new standard for image compression.
Here is a summary of the advantages of JPG4 over JPEG:
- Improved image quality
- Smaller file sizes
- Support for a wider range of color spaces

Lossy compression
Lossy compression is a type of data compression that reduces the size of a file by removing some of the data. This can result in a loss of quality, but it can also significantly reduce the file size. JPG4 uses a lossy compression algorithm, which means that some of the original image data is lost when the image is compressed. However, JPG4 uses a more advanced compression algorithm than JPEG, which results in less visible artifacts and a higher overall image quality.
- Reduced file size: JPG4 images are typically smaller in file size than JPEG images, without sacrificing image quality. This can be a significant advantage for applications where file size is a concern, such as web design and mobile photography.
- Improved image quality: Despite using lossy compression, JPG4 produces images with higher quality than JPEG, with less visible artifacts. This is due to JPG4's use of a more advanced compression algorithm.
- Faster transmission: Smaller file sizes mean that JPG4 images can be transmitted more quickly over the internet or other networks. This can be a significant advantage for applications where speed is important, such as online gaming and video conferencing.
- Wider range of applications: JPG4's smaller file size and higher image quality make it suitable for a wider range of applications than JPEG. For example, JPG4 can be used for photography, web design, medical imaging, and even animation.
Overall, lossy compression is a key feature of JPG4 that offers a number of advantages over JPEG. By reducing the file size of images without sacrificing image quality, JPG4 makes it possible to store, share, and transmit images more efficiently.
Improved image quality
One of the key advantages of JPG4 over JPEG is its improved image quality. Despite using lossy compression, JPG4 produces images with higher quality than JPEG, with less visible artifacts. This is due to JPG4's use of a more advanced compression algorithm that is able to better preserve the original image data.
The improved image quality of JPG4 is particularly noticeable in images with fine details or complex textures. For example, in an image of a landscape, JPG4 will be able to preserve the details of the trees and leaves, while JPEG may blur these details. Similarly, in an image of a portrait, JPG4 will be able to preserve the details of the skin and hair, while JPEG may introduce artifacts.
The improved image quality of JPG4 makes it a better choice for applications where image quality is important, such as photography, graphic design, and medical imaging.
Here are some real-life examples of how the improved image quality of JPG4 can be beneficial:
- A photographer can use JPG4 to store and share high-quality images of their work.
- A graphic designer can use JPG4 to create high-quality images for websites and other marketing materials.
- A medical professional can use JPG4 to store and share high-quality medical images.
Overall, the improved image quality of JPG4 is a significant advantage over JPEG. It makes JPG4 a better choice for applications where image quality is important.
Smaller file sizes
The reduced file size of JPG4 images is a significant advantage over JPEG, particularly for applications where file size is a concern. For example, JPG4 is a good choice for web design, where smaller file sizes can result in faster loading times. JPG4 is also a good choice for mobile photography, where smaller file sizes can save storage space on devices.
- Faster loading times: Smaller file sizes mean that JPG4 images can be loaded more quickly on web pages. This can improve the user experience, especially on mobile devices or in areas with slow internet connections.
- Reduced storage space: Smaller file sizes also mean that JPG4 images take up less storage space on devices. This can be a significant advantage for mobile devices, which often have limited storage space.
- Easier to share: Smaller file sizes make it easier to share JPG4 images via email, social media, and other online platforms.
- Reduced bandwidth usage: Smaller file sizes also mean that JPG4 images use less bandwidth to transmit over the internet. This can be a significant advantage for applications that require the transmission of large numbers of images, such as online photo galleries and video streaming services.
Overall, the smaller file sizes of JPG4 images offer a number of advantages over JPEG, making JPG4 a more versatile and efficient image format.
Support for a wider range of color spaces
The wider range of color spaces supported by JPG4 is a significant advantage over JPEG, particularly for applications that require accurate color reproduction. For example, JPG4 is a good choice for photography, graphic design, and video editing.
The Rec. 2020 color space is particularly important for HDR (high dynamic range) images. HDR images have a wider range of brightness and contrast than traditional images, which can result in more realistic and immersive images. However, HDR images require a wider color space in order to accurately reproduce the full range of colors. JPG4's support for the Rec. 2020 color space makes it a good choice for storing and sharing HDR images.
Here are some real-life examples of how the wider range of color spaces supported by JPG4 can be beneficial:
- A photographer can use JPG4 to store and share high-quality HDR images that accurately reproduce the full range of colors.
- A graphic designer can use JPG4 to create high-quality images for websites and other marketing materials that accurately represent the colors of the products or services being promoted.
- A video editor can use JPG4 to store and share high-quality HDR videos that accurately reproduce the full range of colors.
Overall, the wider range of color spaces supported by JPG4 is a significant advantage over JPEG. It makes JPG4 a more versatile and accurate image format for a wider range of applications.
Backward compatibility
