File Format Information
- JPG (JPEG Image) is a lossy image compression format, compression method is usually lossy, based on the discrete cosine transform (DCT), encodings include: Sequential Encoding, Progressive Encoding, Lossless Encoding and Hierarchical Encoding. This format compresses the data and reduces the file size as much as possible without losing too much image quality. The file extensions can be .jpg, .jpeg.
- PNG (Portable Network Graphics) is a raster graphics file format, uses a non-patented lossless data compression and offers a variety of transparency options. There are three types of PNG formats: PNG-8, PNG-24 and PNG-32. PNG-8 use 8-bit colors (256 colors), it has a smaller size and higher compression. PNG-24 use 24-bit colors ans has better image quality, but it has a large size. PNG-32 add 8 bits transparency information to 24-bit image, so it supports semi-transparent.
