HPI Converter is a conversion utility for HPI files to be formatted into PNG files with alpha transparency. This software also works from Hemera Browser. You will drop one or more files from your browser and save the PNG files anywhere you choose. To help you ensure that you have chosen the right files to convert, HPI converter also shows a preview of the pictures. HPI files are associated with Hemera Photo Objects [images]. The HPI file contains a fixed 32-byte header resembling the header used in PNG [Portable Network Graphics] file. The color image data is presented in JPEG format following this header. If you follow the main image, the grayscale mask data is presented as PNG format. This will achieve good compression of the image data and excellent compression for the grayscale mask data that is dominated usually by pure black and pure white pixels.
