The .ICO filename extension refers to the ICON image file format originally developed by Microsoft. The extension is used to represent computer icon images of varying sizes designed for the operating system Microsoft Windows. Its use today has extended to developing icons for programs designed using the Microsoft developer's suite Visual Studio and other applications. Similar to other device independent bitmap file formats, the ICON file format is also in the raster graphics class of image formats where each individual pixel is part of an orthogonal dot matrix data structure with support for a limited palette of color information. As a resource file, the .ico file format has its strength in contextual use. This allows for multiple icon images of different color depth or size to be stored within the resource file and used when appropriate.
The Picture Exchange file format, shortened PCX, with the .pcx filename extension is an image file format developed by ZSoft Corporation. It was initially released in 1985 as a lossless bitmap image format and for a time was the default file format for PC paintbrush. The format is now largely superseded by other formats given the target platforms for the software associated with the format are no longer in production, i.e. MS DOS and Windows 1.0.
FreeFileConvert uses tuned encoding for ICO to PCX conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload ICO files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized PCX results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent PCX audio with dependable progress tracking.
Each .ico file begins with an icon directory specifying the number of images, color depth, and size. Through its history, ICON file formats have come from containing images at a resolution from 32x32 in monochrome, to containing images up to 256x256 in resolution with up to 16.7 million colors.
Later iterations of the format supported 24bit color palette, upgrading from the original 2 to 4 colors. Byte ordering used by the format is little endian ordering with three blocks; a 128 byte header, image data and an optional 256 color palette. Image data is stored in an orthoganal arrangement of scan lines ordered from the top to the bottom. Files can eiher be compressed using the simple RLE (Run Length Encoding) algorithm or uncompressed.
