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 TIFF format was developed by the company Aldus in 1986, which was later acquired by Adobe systems who now own the rights on the format specification. TIFF, which refers to the Tagged Image File Format, is a raster graphics file format popularly used in desktop publishing and print. Its initial development goal was to create an alternative and cross platform format that would replace the numerous proprietary formats used by scanners developed in the 80's. Later revisions, after Adobe took over the development of the format, saw the TIFF format become extensible to adapt with growing and changing needs of the graphics industry. TIFF supports high color depth and is well suited to OCR applications, scanning, image editing and authoring as well as word processing. The format uses the filename extension .tiff for files stored in the format.
FreeFileConvert uses tuned encoding for ICO to TIFF 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 TIFF 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 TIFF 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.
The original version of the TIFF format had no support for compression but by the 5th release of the format, LZW compression (a lossless compression algorithm) was supported. However, the format can also be used to store data in a lossless format without compression. This cannot be done though if the TIFF file is acting as an archive for JPEG data which is inherently lossy. TIFF supports monochrome, grayscale, palette color, and full true color.
