What Is This Tool?
This tool enables you to convert XBM (X BitMap) files, which are plain-text C source image files for monochrome bitmaps, into a compressed 7Z archive. This process packages multiple XBM files into a single container with strong compression and optional encryption, simplifying storage and transfer.
How to Use This Tool?
-
Upload your .xbm files or entire folders containing XBM bitmaps
-
Choose 7Z as the output archive format
-
Optionally enable AES-256 encryption for secure archives
-
Start the conversion to package XBM files into a single .7z archive
-
Download the compressed and archived 7Z file for storage or distribution
Key Features
-
Converts human-readable XBM bitmap source files into compressed 7Z archives
-
Supports packaging multiple XBM files preserving directory layout
-
Uses high compression ratios with LZMA/LZMA2 algorithms in 7Z format
-
Optional strong AES-256 encryption for secure archiving
-
Creates multi-volume split archives for easier file transfers
Examples
-
Bundle a directory of XBM icon files into one 7Z archive for easy transfer to another developer
-
Create an encrypted 7Z backup of embedded-system bitmap assets for secure offsite storage
-
Package legacy XBM cursor bitmaps into a compressed archive to reduce application installer size
Common Use Cases
-
Distributing collections of legacy XBM bitmaps with software installers
-
Archiving embedded-system monochrome graphics in secure, compressed containers
-
Grouping multiple small XBM files to preserve directory structure during migration
-
Reducing download size of bitmap assets by compressing them into 7Z archives
Tips & Best Practices
-
Ensure XBM files are correctly formatted as 1-bit monochrome bitmaps before conversion
-
Use encryption only when strong protection of bitmap data is required
-
Be aware that 7Z solid compression can slow extraction of individual files
-
Use updated 7Z extraction tools that fully support LZMA2 and encryption features
-
Keep backups of original XBM sources as 7Z archives do not improve image color or metadata
Limitations
-
XBM format only supports 1-bit monochrome images with limited metadata
-
Compressed archives cannot add color or richer metadata to XBM bitmaps
-
7Z solid compression may increase overhead when extracting single files
-
Some operating systems require third-party tools to open 7Z archives
-
Compression and decompression may be resource-intensive on low-power hardware
Frequently Asked Questions
-
What is an XBM file used for?
-
XBM files store monochrome bitmap images as plain-text C source code and are commonly used for embedding icons or cursors in X11 applications.
-
Why convert XBM files into 7Z archives?
-
Packaging XBM files into 7Z archives reduces their storage size, preserves directory structure, and allows optional encryption for secure backup or distribution.
-
Do 7Z archives add color or metadata to XBM images?
-
No, the 7Z archive format only compresses and packages the files; it does not enhance the color depth or metadata of the original XBM images.
-
Can all devices extract 7Z archives?
-
Not all operating systems have native support for 7Z files; third-party extraction tools are often required.
Key Terminology
-
XBM
-
A plain-text C source file format for 1-bit monochrome bitmaps, mainly used in X11 applications.
-
7Z
-
An open archive format using high compression algorithms like LZMA and supporting features such as AES-256 encryption.
-
AES-256 Encryption
-
A strong encryption standard used to secure archive contents and optionally their headers in 7Z files.
-
Solid Compression
-
A compression technique in 7Z archives that compresses multiple files together for higher compression ratios but makes extraction slower.
