Convert PCX to JFIF

The PCX file extension, standing for PiCture eXchange, is a raster image format developed by ZSoft Corporation in 1985 for its PC Paintbrush software. It became one of the first widely accepted DOS imaging standards, supporting palette-indexed images from 2 to 256 colors and later true-color (24-bit) images. PCX files use RLE (Run-Length Encoding) compression, making them smaller in size. Although largely replaced by formats like BMP, JPEG, and PNG, PCX was pivotal in early computer graphics and is still supported by various image processing software.

The JPEG File Interchange Format (JFIF), developed by the Joint Photographic Experts Group, is a standardized method of storing and transferring JPEG-compressed images. Introduced in 1991, JFIF ensures compatibility and interoperability among different platforms and applications. It is extensively used in digital imaging and multimedia for efficient image compression, which reduces file size without significant loss of quality. As a widely adopted format, JFIF supports a range of devices and software, making it a cornerstone in computer graphics and online image sharing.
