JPEGformátumba

JPEGformátumba is a proposed image file concept that seeks to extend the JPEG family by introducing an optional, extensible container that sits alongside standard JPEG bitstreams. It is not an officially adopted format, and there is no formal standard as of today. The term combines JPEG with a fictional suffix intended to signal a transformative, format-wide augmentation.

Concept and structure

The idea behind JPEGformátumba is to preserve the broad compatibility advantages of JPEG by keeping a core JPEG-encoded image while adding an expandable layer for modern features. In theory, the base layer remains a conventional JPEG image, allowing existing decoders to render the picture, while the auxiliary layer carries additional data such as richer metadata, color management options, or feature flags. The extension could be implemented via designated application segments or a separate container within the file, designed to be ignored by legacy decoders.

Features and goals

Proponents describe several potential goals: improved metadata handling (including extended XMP or ICC profiles), optional support for higher color precision or wide color gamuts, enhanced progressive rendering, and better interoperability with content management workflows. The concept emphasizes backward compatibility, aiming to avoid breaking existing JPEG pipelines while enabling newer capabilities for future tools and applications.

Status and usage

As of the current status, JPEGformátumba remains a hypothetical or experimental concept discussed in theoretical or demonstration contexts. It has no formal specification, limited or no official tooling, and no widespread adoption. It is primarily of interest to researchers, standards discussions, and enthusiasts exploring how to evolve the JPEG ecosystem without sacrificing broad compatibility.
