PJPEG to ICO
File Converter

PJPEG (Joint Photographic Experts Group) is a widely used method of lossy compression for digital images. It is particularly well-suited for photographs and realistic paintings, and it works by reducing image file size with a slight sacrifice in quality. The amount of compression can be adjusted, allowing for a trade-off between storage size and image quality.

ICO is a file format used to store icons on Microsoft Windows. It supports images of various sizes and color depths, and it can contain multiple images within a single file, allowing icons to be displayed in different resolutions and color depths depending on the user’s settings. While ICO files are essential for creating application and file icons in Windows, they are less commonly used for other purposes due to their specific functionality and limited support on non-Windows platforms.
