What Is This Tool?
This tool converts XBM files, a plain-text format used for 1-bit monochrome bitmaps, into ZIP archives. It bundles multiple XBM images into a single compressed file, simplifying storage, transfer, and distribution while maintaining compatibility across platforms.
How to Use This Tool?
-
Upload one or more XBM files that you want to archive.
-
Select ZIP as the output archive format for packaging.
-
Click the convert or archive button to start processing.
-
Download the resulting ZIP file containing your XBM bitmaps.
-
Extract individual XBM files later using any ZIP-compatible unzip tool.
Key Features
-
Converts XBM plain-text bitmap files into ZIP archive format.
-
Bundles multiple XBM files into a single compressed package.
-
Lossless per-file compression within the ZIP format.
-
Cross-platform compatibility for Windows, macOS, and Linux.
-
Creates a central directory index for easy file extraction.
-
Supports widely used ZIP compression methods like DEFLATE.
Examples
-
Package a directory of XBM cursors and icons into a ZIP for easy distribution with X11 applications.
-
Archive firmware bitmap assets stored as XBM source files into a ZIP file for backup or team sharing.
-
Send multiple XBM bitmaps in a single ZIP email attachment to simplify cross-platform exchange.
Common Use Cases
-
Distributing sets of XBM icons and cursors bundled for legacy Unix or X11 toolkits.
-
Backing up collections of tiny monochrome bitmaps used in embedded systems.
-
Packaging multiple XBM source files into one easily transferable archive for software deployment.
Tips & Best Practices
-
Use ZIP compression to reduce file size but be aware it may not achieve solid archive level compression.
-
Ensure XBM files are correctly oriented before packaging as ZIP does not alter image orientation.
-
Use ZIP64 extension when archiving very large collections to avoid size limitations.
-
Verify compatibility of ZIP encryption methods if applying password protection.
Limitations
-
XBM supports only 1-bit monochrome images; no grayscale or color data is preserved.
-
XBM files can be larger and less efficient than binary bitmap formats.
-
ZIP compression is per-file and may not reduce size as much as solid archive formats.
-
Some byte or bit order conventions in XBM may cause orientation differences in certain applications.
-
Legacy ZIP encryption is weak; stronger encryption is vendor-dependent and not universally supported.
Frequently Asked Questions
-
What is an XBM file used for?
-
XBM files store 1-bit monochrome bitmap images in plain-text C source code, often used for embedding icons or cursors in X11 applications or embedded systems.
-
Why convert XBM files into ZIP archives?
-
Converting XBM files into ZIP archives bundles multiple bitmap sources into one file for easier distribution, backup, and cross-platform transfer with lossless compression.
-
Can a ZIP archive contain color images converted from XBM?
-
No, since XBM files support only monochrome images, any ZIP archive of XBM files will contain only monochrome bitmaps without grayscale or color.
Key Terminology
-
XBM
-
A plain-text C source format for 1-bit monochrome bitmaps used mainly in X Window System applications.
-
ZIP
-
A popular archive format that stores multiple files in a single container with compression and indexing.
-
DEFLATE
-
A common lossless compression method used within ZIP archives to reduce file size.
