Apple never stops to surprise us. With the iPhone 16 Pro, you can take photos in a new extension – JPEG XL, a new format that takes photos to the next level. What makes it so good and what new things does this encoding method have to offer? Let’s get into specifics about the innovation.
Understanding JPEG XL
Back in 1992, the well-known and widely used JPEG format was created. It was a breakthrough in the field of photography. Time goes on, and technologies change and require modification and evolution! Since then, there has been no format invented to replace JPEG. The goal was to keep the quality high, but, at the same time, to reduce the size and make this new format as popular as JPEG. Therefore, the world is already familiar with such formats as PNG, HEIC, WebP, etc. But each of these formats lacks something.
So, in 2022, the same company released a new format, JPEG XL, that would revolutionize the world of photo encoding and decoding! So, what is this format? JPEG XL is an image compression format, designed to offer superior compression efficiency and image quality compared to existing standards like JPEG and WebP. That’s it in brief, but now let’s move on to a more detailed description.
Benefits of JPEG XL
- Improved compression efficiency: JPEG XL offers better compression efficiency and makes files smaller without affecting the quality. This is particularly beneficial for reducing bandwidth usage and storage requirements in various digital applications.
- Lossless and Lossy Compression: JPEG XL supports both lossless and lossy compression modes, so that users can choose the compression method that best suits their specific requirements. This adaptability makes it an excellent choice for a wide range of image editing tasks.
- Transparency and Animation: JPEG XL offers support for both transparency and animation features, making it an excellent choice for developing intricate graphical elements like logos, illustrations, and animated visuals. This adaptability expands the possibilities for artistic expression and creation of dynamic visuals.
- Progressive Decoding: JPEG XL supports progressive decoding. So, images first appear at reduced resolutions while progressively loading additional data for better quality. This feature improves user experience, ensuring a seamless and responsive display, especially in limited bandwidth environments.
- Potential Impact and Adoption: As the digital imaging sector advances and the need for efficient image compression grows, JPEG XL may have a noticeable impact. Its superior compression features and adaptable capabilities make it an attractive option for a variety of uses, such as web development, online retail, multimedia production, and digital artwork.
The integration of JPEG XL is anticipated to optimize image delivery, minimize loading time, and improve the overall visual experience for users across various platforms and devices. Its compatibility with current software applications and browsers—along with its comprehensive feature set—positions it as a promising standard in the future landscape of image compression.
Lossless compression is a type of compression that allows lossless recovery of original information from compressed data.
Lossy compression recovers only a portion of the original data, thus reducing the size of the medium.
Comparison of formats: JPEG XL vs HEIC vs RAW
If there’s such a wide range of formats to choose from, how do you figure out which option is best for you, an iPhone user? For this purpose, we will compare popular formats: JPEG XL, HEIC and RAW.
JPEG XL
JPEG XL is a modern image compression format developed by the JPEG Committee. It aims to provide better compression efficiency than the traditional JPEG format while maintaining high image quality.
Key Features:
- Improved Compression: JPEG XL uses advanced compression techniques to reduce file size without affecting image quality.
- Lossless or Near-Lossless Compression: it supports both lossy and lossless compression, allowing users to choose the level of quality preservation.
- Dynamic Metadata: JPEG XL can store metadata such as color profiles, depth maps, and animations within the image file.
HEIC
HEIC is a file format introduced by Apple to replace JPEG on iOS devices. It offers improved compression efficiency and supports features like transparency and image sequences.
Key Features:
- Reduced File Size: HEIC files are generally smaller in size compared to JPEG files with similar image quality.
- Better Image Depth: HEIC supports 16-bit color depth, which makes images more vivid and detailed.
- Advanced Compression Algorithms: The format uses HEVC (High-Efficiency Video Coding) for superior compression performance.
RAW
RAW is an uncompressed image format that contains minimally processed data from the camera’s sensor. It preserves the highest image quality and provides greater flexibility for post-processing.
Key Features:
- Uncompressed Data: RAW files retain all the original data captured by the camera sensor, offering the highest level of image quality.
- Flexible Editing: since RAW files are unprocessed, they allow photographers to make extensive adjustments to exposure, color, and other parameters.
- Preservation of Image Details: RAW files preserve fine details, making them ideal for high-quality prints and professional editing.
Choosing the Right Format:
- JPEG XL: Ideal for web and mobile use, balancing compression efficiency and image quality.
- HEIC: Recommended for iOS users due to its space-saving capabilities and support for advanced features.
- RAW: Suited for professional photographers and enthusiasts who prioritize image quality and post-processing flexibility.
