A PDF can most certainly use image compression. Most often it uses medium quality JPEG. Depending on how the conversion occurs it can also down sample the image resolution to 150 dpi. There are several different compression methods that could be used: None, LZW, 4bit ZIP, 8bit ZIP, JPEG, JPEG2000, JBIG, CCITTG4, CCITTG3. All depends on how the software is configured.
