ICO

ICO files are optimized for storing iconic images used in Windows applications, allowing for multiple resolutions and color depths. They enhance user interfaces by providing scalable and high-quality graphics for programs and shortcuts. As a versatile image format, ICO files support both static and animated icons, making them essential for software developers and designers aiming for a polished visual appearance.

PGM

The Portable Gray Map (PGM) format is a simple, portable image file that represents grayscale images. It is part of the Netpbm format family, suitable for easy manipulation and conversion. PGM files store pixel intensity values in plain text or binary, ensuring broad compatibility across various platforms and applications. Ideal for graphic designers and developers looking for a straightforward approach to grayscale image processing.
