Introducing Jpegli: Google’s New JPEG Coding Library

The internet changes fast, especially with stuff like pictures and links. In the last ten years, things have gotten faster and safer. One big change is how we compress images, with formats like WebP, AVIF, and now Jpegli, Google’s newest one, making a splash. So, what’s Jpegli, and why should you care?

Understanding Jpegli: A Breakdown

Jpegli, short for JPEG Lightweight Image, represents Google’s fresh venture into the world of open-source JPEG coding libraries. The suffix “li” derives from Swiss German dialects, translating to “small.” Essentially, Jpegli serves the purpose of significantly reducing the file size of JPEG images while maintaining image quality and minimizing compression artifacts.

Backward Compatibility and Enhanced Efficiency

Jpegli boasts backward compatibility, ensuring that images encoded with this library can be effortlessly opened by programs supporting traditional JPEG formats. However, what sets it apart is its ability to achieve a 35% reduction in file size compared to conventional JPEG compression methods. Moreover, Jpegli adopts a 10+ bits per component approach, surpassing the standard 8-bit component coding of traditional JPEGs. This enables it to deliver superior image quality and efficiency.

Advantages Over WebP

In comparison to its predecessor, WebP, Jpegli exhibits notable advantages. With its faster and higher-quality compression, Jpegli emerges as a superior option for optimizing image storage and enhancing web page loading speeds. Its efficiency in resource utilization makes it a preferred choice for web developers seeking optimal performance without compromising on image quality.

Implementing Jpegli: Practical Insights

Integration with Existing Platforms: Developers can seamlessly integrate Jpegli into existing platforms and content management systems to streamline the optimization process.

Performance Testing: Conducting thorough performance tests can aid in evaluating the effectiveness of Jpegli in optimising image delivery and enhancing website performance.

Updating Content Management Systems: Ensuring that content management systems are updated to support Jpegli encoding is essential for maximising its benefits.

Why Jpegli Is Important for Us

Interoperability and Compatibility: Jpegli offers both an encoder and decoder fully compliant with the original JPEG standard and its conventional 8-bit format. Furthermore, it ensures API/ABI compatibility with libjpeg-turbo and MozJPEG.

High Quality Results: Utilizing Jpegli for image compression or decompression leads to more precise and visually effective computations. This results in clearer images with fewer noticeable artifacts.

Speed: Jpegli maintains coding speed comparable to traditional methods such as libjpeg-turbo and MozJPEG, while also improving the quality-to-compression ratio. This means web developers can integrate Jpegli seamlessly into their workflows without sacrificing speed or memory efficiency.

10+ Bits Encoding: Jpegli supports encoding with 10+ bits per component, surpassing the limitations of traditional JPEG codecs which only offer 8 bits per component. This helps mitigate visible banding artifacts in gradients. The 10+ bit encoding is seamlessly integrated within the original 8-bit framework, ensuring compatibility with 8-bit viewers. Implementing this feature requires application code adjustments and is available as an API extension.

Higher Compression Efficiency: Jpegli compresses images more efficiently than traditional JPEG codecs, resulting in bandwidth and storage savings. This efficiency also contributes to faster loading times for web pages.
