What is an JBIG file?
The ‘.JBIG file extension’ stands for Joint Bi-level Image Group File. It is primarily associated with files that store bi-level (black-and-white) images using a specific compression technique.
Developed to efficiently encode such images, ‘.JBIG files’ are commonly used for fax transmissions, document storage, and other applications where compactness and fidelity are essential.
More Information.
JBIG was first standardized in 1993 with the release of JBIG1, which focused on achieving high compression rates for bi-level images.
It was later improved with JBIG2 in 2000, offering even better compression efficiency and additional features like progressive transmission and embedded text coding.
These advancements made JBIG2 suitable not only for fax and document storage but also for digital libraries, archives, and other applications requiring high-quality bi-level image compression.
Origin Of This File.
The Joint Bi-level Image Group (JBIG) format was developed by the Joint Bi-level Image Experts Group, hence the acronym ‘JBIG’.
This group, formed in the early 1990s, aimed to create a standard for encoding bi-level images that would be more efficient than existing methods like TIFF.
JBIG was particularly designed to handle binary images with high compression ratios, making it ideal for use in telecommunications and document imaging.
File Structure Technical Specification.
JBIG files typically consist of compressed bi-level image data. The compression technique used in JBIG files exploits patterns and redundancies commonly found in bi-level images (such as text documents) to achieve significant compression ratios.
The JBIG2 standard supports various compression modes, arithmetic coding, and a wide range of image resolutions and sizes.
How to Convert the File?
Converting .JBIG files to other formats may be necessary for compatibility or editing purposes. Here are common conversion methods:
- Using Conversion Software: Dedicated image conversion tools like Adobe Acrobat or online converters can convert .JBIG files to formats like TIFF or PDF.
- Using Print to PDF Feature: Print the .JBIG file using a virtual PDF printer to create a PDF version.
- Image Editors: Open the .JBIG file in an image editor that supports bi-level images and save/export it in another format like PNG or BMP.
Advantages And Disadvantages.
Advantages:
- High Compression Efficiency: JBIG files can achieve very high compression ratios, often surpassing other formats like TIFF for bi-level images.
- Lossless Compression: The compression used in JBIG files is typically lossless, preserving the quality of the original image without degradation.
- Support for Progressive Transmission: JBIG2 supports progressive encoding, allowing images to be displayed at low resolution initially and gradually improving quality as more data is received.
- Embedded Text Coding: Text and line art can be encoded more efficiently in JBIG2, reducing file sizes further.
Disadvantages:
- Complexity: Implementing JBIG2 encoding and decoding can be more complex compared to simpler formats.
- Compatibility Issues: Not all software applications and systems fully support JBIG files, especially older versions that may only support JBIG1 or have limited JBIG2 support.
How to Open JBIG?
Open In Windows
- JBIG files can be opened on Windows using applications like Adobe Acrobat Reader, which supports viewing and printing PDF documents containing embedded JBIG images.
Open In Linux
- On Linux systems, applications like Evince (Document Viewer) or Okular are capable of opening JBIG images within PDF files.
Open In MAC
- MacOS users can utilize Preview, the default image viewer, which supports viewing JBIG images embedded within PDF documents.
