Convert PBM to GIF

The PBM (Portable Bitmap) file extension, part of the Netpbm project, originated in the late 1980s to facilitate efficient and portable graphics file interchange. Primarily, PBM files are used to store monochrome bitmaps in a simple ASCII text format, ensuring easy compatibility across different systems and platforms. This format supports only black-and-white imagery, making it particularly useful in scenarios where simplicity and minimalism are prioritized, such as in Unix environments for bitmap manipulation and transfer. Its historical significance lies in promoting a standardized approach to bitmap graphics in early computer technology.

The Graphics Interchange Format (GIF) is a bitmap image format developed by CompuServe in 1987. It is widely used for its support of animated images, allowing for the compression of graphics with low file sizes and without compromising quality. It's particularly popular on the internet for memes, short animations, and simple graphics due to its ability to loop animations seamlessly. GIFs support up to 256 colors and use the LZW compression algorithm to minimize file size. The format's historical significance lies in its ability to efficiently store and transmit images in an era of slower internet speeds and remains a staple in digital communication and web design today.
