What is WBMP?
WBMP (Wireless Bitmap) is a legacy monochrome image format defined by the WAP specifications for early mobile phones. A .wbmp stores 1-bit pixels (black/white) in a compact, header-light structure using multi-byte integers, optimized for tiny screens and low bandwidth. Because WBMP lacks color, alpha channels, EXIF, or ICC profiles, files are extremely small but visually limited. Typical uses were operator logos, icons, and simple splash screens delivered via WAP push, SMS/MMS, or early mobile web pages. Modern devices and browsers rarely need WBMP; PNG, SVG, and WebP are preferred. You can still open or convert WBMP in tools like ImageMagick and some editors, or batch convert to PNG when migrating old assets.
What is ICO?
ICO is the Windows icon format: a small container that bundles multiple bitmap images at different sizes and color depths into a single .ico file. Typical entries include 16×16, 32×32, 48×48, and 256×256 pixels, with 24-bit or 32-bit color and alpha transparency. Modern ICO images may be stored as PNG (compressed) or legacy BMP (uncompressed), allowing crisp edges and smooth scaling across displays. ICO files are used for application and file icons in Windows and as classic website “favicon.ico,” though browsers also accept PNG/SVG today. You can create or convert ICO with tools like IcoFX, GIMP, Photoshop (plugins), ImageMagick, and many online converters. Because ICO is a simple container, it’s broadly supported and easy to generate from SVG or high-resolution PNG sources.
