What Is This Tool?
This tool converts JBG files, which are losslessly compressed bi-level (1-bit) images, into 7Z archive format. It bundles one or more JBG images into a single compressed archive using high-efficiency LZMA/LZMA2 compression, enabling compact storage, optional AES-256 encryption, and multi-volume archives for easy transfer and long-term archiving.
How to Use This Tool?
-
Upload your JBG files to the converter interface.
-
Select 7Z as the output archive format.
-
Choose optional settings such as encryption or multi-volume archives if needed.
-
Click convert to bundle and compress your JBG files into a 7Z archive.
-
Download the resulting 7Z file for storage or distribution.
Key Features
-
Lossless archiving of JBG bi-level images into 7Z archives
-
High compression ratio using LZMA and solid compression
-
Optional strong AES-256 encryption for secure backups
-
Support for multi-volume (split) 7Z archives
-
Open and cross-platform archive format
Examples
-
Compress a folder of JBG-scanned invoices into a single encrypted 7Z archive for secure off-site storage.
-
Package thousands of bitonal JBG pages into split 7Z volumes to transfer over limited bandwidth networks.
-
Create a compact 7Z archive of JBIG-encoded line art diagrams for archival and quick retrieval.
Common Use Cases
-
Archiving scanned black-and-white document collections with compact, lossless storage.
-
Distributing sets of JBIG-encoded scans as a single compressed file to simplify sharing.
-
Creating encrypted backups of JBG images for secure long-term preservation.
-
Splitting large JBG image collections into multi-volume 7Z archives for transfer across storage media.
Tips & Best Practices
-
Use 7Z's solid compression feature to improve compression ratio for similar JBG files.
-
Enable AES-256 encryption for sensitive scanned documents to protect privacy.
-
Consider multi-volume archives to manage large batches of JBGs across size-constrained media.
-
Remember that extracting individual files may require compatible tools supporting 7Z and JBIG.
-
Keep backups of original JBG files if editing or partial extraction is anticipated.
Limitations
-
The tool only archives JBG files; rendering still requires JBIG/JBG-compatible viewers.
-
7Z solid compression can increase overhead when extracting or modifying single files.
-
Some operating systems require third-party software to open 7Z archives.
-
Compression and decompression may be CPU- and memory-intensive on low-resource devices.
Frequently Asked Questions
-
What type of images can be converted using this tool?
-
This tool works specifically with JBG files, which are bi-level (1-bit) images compressed using the JBIG lossless algorithm.
-
Can I encrypt my JBG archives?
-
Yes, 7Z archives created can include strong AES-256 encryption to secure your files.
-
Will I be able to view my JBG images after they are archived in 7Z?
-
You must extract the files from the 7Z archive and use a JBIG/JBG-compatible viewer to open them, as archiving does not change the image format.
Key Terminology
-
JBG
-
A file format storing bi-level images compressed losslessly using the JBIG algorithm, optimized for text and line art.
-
7Z
-
An open archive file format supporting high compression ratios, multi-volume archives, and AES-256 encryption.
-
LZMA Compression
-
A compression method used by 7Z archives that provides high compression ratios using dictionary compression.
