About formats

ICO is the icon file format for Microsoft Windows, introduced with Windows 1.0 in 1985 and serving as the standard container for application icons, file type icons, and shortcut icons throughout the Windows ecosystem. An ICO file bundles multiple image variants within a single container — each at different sizes (16x16, 32x32, 48x48, 256x256, and others) and color depths (4-bit, 8-bit, 24-bit, 32-bit with alpha) — allowing Windows to select the most appropriate image for each display context, from tiny taskbar buttons to large desktop icons. The container structure consists of an ICONDIR header, an array of ICONDIRENTRY records describing each variant, and the image data itself. Since Windows Vista, ICO files support embedded PNG-compressed images for the larger sizes (typically 256x256), dramatically reducing file size while maintaining quality with full alpha transparency. One advantage is automatic size adaptation — Windows pulls the optimal resolution from the ICO container for each context (Explorer list view, desktop tile, Alt-Tab preview), ensuring crisp display without the application managing separate image files. The format's operating system-level integration is another core strength: ICO files serve as the identity mechanism for executables, file associations, and shortcuts across all Windows versions, and web browsers use favicon.ico for website identity in tabs and bookmarks. ICO creation and editing is supported by image editors like GIMP, Inkscape, and dedicated icon tools, and the format remains essential for Windows application development.

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.

Frequently Asked Questions

Why convert ICO to PALM?

Palm bitmap format packages your icon for Palm OS — needed when creating graphics for legacy PDA applications or Palm device emulators.

Which apps support PALM files?

PALM files work with Palm OS devices, Calibre, ImageMagick. Check your operating system for built-in viewer support as well.

Does ICO to PALM keep transparency?

If PALM supports transparency (like PNG or WEBP), the alpha channel from your ICO is preserved. Formats without transparency support fill with a solid background.

What happens to my uploaded files?

Your ICO files are automatically deleted right after conversion. The resulting PALM files remain available for download for 24 hours, then they are permanently removed.

How long does ICO to PALM conversion take?

Most conversions complete within seconds. Processing time depends on file size and server load, but the entire workflow typically finishes in under a minute.

Can I convert ICO to PALM for free?

Yes — Convertio offers free ICO to PALM conversion. For professional volumes and larger files, premium plans provide expanded limits and priority processing.
