Introduction

As digital document workflows evolve, there is a growing need for more efficient and higher quality image compression methods. The PDF format, while established as the standard for document exchange, has historically been limited by its reliance on older image formats like JPEG, PNG, and JPEG 2000. Despite advancements in imaging technology, the PDF standard has not incorporated new image codecs for over 20 years, resulting in inefficiencies in both file size and image quality.

This white paper explores the advantages of integrating JPEG-XL—a next-generation image compression standard—into the ISO PDF standard and PDF/Raster, and how it can unlock new levels of inefficiency, quality, and flexibility for modern document management.

Overview of JPEG-XL

JPEG-XL is a modern image compression standard designed to provide:

1. High compression ratios while maintaining superior image quality, surpassing older formats like JPEG and PNG.

2. Support for both lossless and lossy compression, offering flexibility based on the specific needs of the document or image.

3. Advanced features such as progressive decoding, support for HDR (High Dynamic Range), and wide color gamuts.

4. Backward compatibility with older formats like JPEG, ensuring a smooth transition to newer technologies.

These features make JPEG-XL a powerful candidate for integration into PDF, addressing many of the limitations that have persisted due to the lack of new image codecs in the PDF ecosystem.
