Explain how the compression software will compress the image file.
Answer
The compression software reduces the file size of the image by applying various algorithms. These algorithms identify repetitive patterns or data in the image and store them more efficiently. For example, a lossless compression method might use a technique such as Run-Length Encoding (RLE) to replace sequences of the same pixel value with a single value and a count, thus reducing the overall file size without losing detail.
