Cloud Conversion

All XBM to XV processing runs on Convertio servers — your device stays fast and free while the conversion happens in the cloud.

Modern Format Output

XV provides thumbnail format from the XV image viewer — a significant upgrade over the legacy XBM format for everyday image use and sharing.

Simple Interface

Three steps to convert: upload your XBM, select XV, and download. The clean interface makes the process intuitive even for first-time users.

2

Choose xv or any other format you need as a result (more than 200 formats supported)

3

Let the file convert and you can download your xv file right afterwards

About formats

XBM (X BitMap) is a monochrome (1-bit) image format defined as part of the X Window System, originating at MIT around 1987. XBM files are unique among image formats in being valid C source code: each file defines the image as a static array of unsigned char values containing the packed pixel data, preceded by #define statements specifying the image width, height, and optional hot-spot coordinates (for cursor images). The pixel data is stored in hexadecimal byte values within curly braces, with each bit representing one pixel (1 = foreground, 0 = background) and bits ordered LSB-first within each byte. This design was intentional — XBM images could be #included directly into X Window application source code and compiled into the binary, eliminating the need for external file loading and runtime format parsing. The format was used throughout the X11 ecosystem for cursor shapes, window icons, toolbar buttons, and other small UI elements. One advantage is the source-code nature of the format: XBM files can be edited with a text editor, diff'd and merged in version control, generated by shell scripts, and compiled directly into C programs without any image loading library — a level of toolchain integration that no binary image format can match. The format's role as part of the X Window standard ensures it is understood by every X11-aware toolkit and application. While limited to monochrome and no compression, XBM's simplicity makes it an excellent teaching format for understanding bitmap representations. XBM files are supported by all X11 applications, ImageMagick, GIMP, web browsers (as a legacy web format), and programming environments.

XV is an alternate file extension for the VIFF (Visualization Image File Format) developed by Khoral Research as part of the Khoros scientific image processing environment, which originated at the University of New Mexico around 1990. The .xv extension and the .viff extension refer to the same underlying format — a container with a 1024-byte header encoding image dimensions, data type (from single-bit to double-precision float and complex numbers), color space, band count, and optional spatial location metadata, followed by color map data and pixel values. The XV extension became common on systems where Khoros was installed alongside other X Window System tools, and in some research communities .xv was preferred over .viff as a shorter alternative. Khoros itself was a pioneering visual programming system where scientists assembled image processing pipelines by wiring together processing nodes in a graphical canvas — an approach that predated and influenced similar environments in MATLAB, LabVIEW, and commercial remote sensing packages. One advantage of the VIFF/XV format is its ability to store data at scientific precision levels — floating-point and complex number pixel values preserve measurement accuracy that would be lost in photographic formats limited to 8-bit or 16-bit integers, making it valuable for spectral analysis, computational physics output, and satellite imagery. The multi-band architecture provides another strength, allowing a single file to hold dozens of spectral channels from multispectral or hyperspectral sensors without splitting data across multiple files. XV files are supported by ImageMagick and can be converted to modern image formats for visualization or publication.

Frequently Asked Questions

What is the reason to convert XBM to XV?

XBM is a monochrome bitmap from the X Window System with limited modern support. Converting to XV (thumbnail format from the XV image viewer) makes your images accessible on any modern platform.

Which software can view XV files?

XV files can be opened with XV viewer, ImageMagick, GIMP. Most of these are available across Windows, macOS, and Linux.

Is my XBM file safe when converting online?

Convertio takes privacy seriously — your XBM uploads are deleted after conversion and the XV results are cleared within 24 hours.

Can I convert multiple XBM files to XV at once?

Absolutely. Batch upload your XBM images and convert them all to XV in a single pass — no need to repeat the process for each file.

What platforms support this XBM converter?

Since it runs in the browser, any operating system works — desktop or mobile. No platform-specific software is needed to convert XBM to XV.

Does converting XBM to XV affect quality?

Your image content stays intact during conversion. Any differences depend on XV characteristics — such as color depth or compression method.
