PEF to JPS
File Converter

PEF stands for Pentax Electronic File, and it is a raw image file format used by Pentax digital cameras. This format stores unprocessed image data directly from the camera's sensor, allowing photographers to maintain a high level of control over image adjustments such as exposure, color balance, and sharpness during post-processing. PEF files provide the potential for higher image quality, as they preserve more information than standard compressed image formats.

JPS is one of the most widely used image file formats, favored for its efficient lossy compression algorithm that significantly reduces file size while maintaining a high image quality. It is commonly used for photographs and web graphics; however, the lossy nature of its compression means that some image quality is sacrificed, and this loss can be exacerbated with repeated editing and saving. JPG files support 24-bit color, allowing for a broad spectrum of colors, but they do not support transparent backgrounds.
