About formats

PALM is a bitmap image format used by the Palm OS operating system, introduced in 1996 with the original Palm Pilot 1000. Palm bitmap files store raster images in formats optimized for the extremely constrained hardware of early Palm handheld devices — the original models featured a 160x160 pixel monochrome (2-shade) display, 128 KB of RAM, and a 16 MHz Motorola 68328 processor. The format evolved through several versions as Palm hardware improved: PalmOS 1.0 supported 1-bit monochrome, later versions added 2-bit (4 shade grayscale), 4-bit (16 shade), 8-bit (256 color), and eventually 16-bit (65536 color) direct color modes. Palm bitmaps use a simple header specifying width, height, row bytes, flags, and bit depth, followed by the pixel data which may use optional Scanline compression (a PackBits-like run-length encoding) or dense packing. The format also supports bitmap families — multiple versions of the same image at different bit depths bundled together, allowing the OS to select the best version for the current device's display capabilities. One advantage is the format's documentation of early mobile computing: Palm OS was the dominant handheld platform of the late 1990s and early 2000s, and Palm bitmap files from applications, games, and content of that era represent important artifacts of mobile computing history. The multi-depth bitmap family feature provides another notable design strength — a single resource could serve devices ranging from monochrome Palm Pilots to the 16-bit color Sony CLIE and Palm Tungsten. PALM bitmaps are supported by ImageMagick, pilot-link utilities, and Palm emulator tools.

WBMP (Wireless Bitmap) is a monochrome (1-bit, black and white) image format defined as part of the Wireless Application Protocol (WAP) specification, developed by the WAP Forum (later consolidated into the Open Mobile Alliance) around 1998. The format was designed for the extremely constrained mobile devices of the late 1990s and early 2000s — phones with small monochrome screens, minimal processing power, and narrow bandwidth GSM data connections. WBMP uses the simplest possible encoding: a type identifier byte (always 0 for the only defined type), width and height encoded as multi-byte integers using a variable-length scheme, and the raw pixel data where each bit represents one pixel (0 for white, 1 for black) packed eight per byte. There is no compression, no metadata, and no color — the format is purely a minimal container for delivering small monochrome graphics to WAP-era mobile browsers. One advantage was extreme efficiency on constrained devices — WBMP images could be decoded with virtually zero CPU overhead and minimal memory, critical on early mobile hardware running at single-digit megahertz clock speeds. The tiny file sizes are another strength: a typical WBMP icon occupied just a few hundred bytes, practical for transfer over 9.6 kbps GSM data channels. While the WAP ecosystem has been entirely superseded by modern mobile web browsers capable of rendering full-color JPEG, PNG, and WebP images, WBMP files remain encountered in archived mobile content from that transitional era.

Frequently Asked Questions

Why convert PALM to WBMP?

Converting PALM to WBMP lets you rescue images from vintage Palm OS devices — WBMP works in virtually any image viewer or web browser available today.

What programs open WBMP files?

You can open WBMP files with any standard image viewer. Windows Photo Viewer, macOS Preview, GIMP, and web browsers all support WBMP.

Where do PALM files come from?

PALM files come from vintage Palm OS devices like Palm Pilots and Handspring Visors. They store low-resolution bitmaps for tiny PDA screens.

What happens to uploaded files?

Your PALM files are processed on secure servers, then deleted automatically. Converted WBMP files are available for 24 hours, then erased.

Does converting PALM to WBMP lose quality?

Conversion preserves the quality present in the PALM original. Any limitations come from the source resolution, not from the conversion step.
