About formats

XPM (X PixMap) is a color image format for the X Window System, developed by Arnaud Le Hors at GROUPE BULL beginning in 1989 as the color successor to the monochrome XBM format. Like XBM, XPM files are valid C source code — each file defines the image as a static array of character strings, where the header strings specify width, height, number of colors, and characters per pixel, the color definition strings map character codes to color values (supporting X11 color names, hexadecimal RGB, and symbolic color types like 'background' and 'foreground'), and the pixel strings encode each row as a sequence of character codes that index the color palette. This ASCII art representation makes XPM images human-readable: one can often see the image content directly in the text of the source file. The format went through three revisions: XPM1 (1989, compatible with X10), XPM2 (simplified syntax), and XPM3 (1991, the current version with the static char* syntax and extended color specification). XPM was the standard format for X Window application icons, splash screens, pixmap buttons, and themed UI elements throughout the 1990s and 2000s. One advantage is the combined benefits of being a valid C source file and a color image: XPM files can be compiled into applications, edited in any text editor, processed by text tools, and version-controlled, while supporting up to 256 colors with transparency (using the 'None' color keyword). The X11 ecosystem's reliance on XPM ensures broad tool support. XPM files are handled by all X11 toolkits, ImageMagick, GIMP, and web browsers (legacy support).
Initial release: 1989
BMP (Bitmap) is a raster image file format developed by Microsoft for the Windows operating system, introduced with Windows 3.0 in 1990. The format stores pixel data in a straightforward structure: a file header specifying dimensions, color depth, and compression method, followed by an optional color palette and then the raw pixel array. BMP supports color depths from 1-bit monochrome through 4-bit and 8-bit indexed color to 16-bit, 24-bit true color, and 32-bit with alpha channel. Most BMP files store pixels uncompressed (BI_RGB), though optional RLE compression is available for 4-bit and 8-bit modes. Pixels are arranged in bottom-up row order by default, with each row padded to a 4-byte boundary. One advantage is absolute simplicity — the format has no complex encoding, filtering, or compression layers, making BMP files trivial to read and write programmatically in any language. This simplicity also means BMP images render with zero decoding overhead, useful in scenarios where decompression latency matters. The format's deep Windows integration is another strength: BMP is the native bitmap format for Windows GDI, clipboard operations, and device-independent bitmap (DIB) handling, ensuring first-class support across the entire Windows ecosystem. While BMP's lack of compression produces large files unsuitable for web use or storage-constrained environments, it remains widely used as an intermediate format in image processing, as a clipboard exchange format, and in embedded systems where decoding simplicity outweighs file size.

Frequently Asked Questions

Why would I convert XPM to BMP?

Few modern tools handle XPM natively. BMP provides uncompressed pixel data, making it widely recognized across operating systems and applications.

What programs open BMP files?

Open BMP using Microsoft Paint, Photoshop, GIMP, any Windows viewer. Cross-platform support means you can access these files on virtually any system.

Does converting XPM to BMP affect quality?

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

Is XPM to BMP conversion free?

Standard conversions are available for free on Convertio. Larger volumes or higher usage may benefit from a premium plan for additional capacity.

Is my XPM file safe when converting online?

Yes — Convertio deletes uploaded files right after conversion. Converted files are removed from servers within 24 hours for complete privacy.

What platforms support this XPM converter?

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