Will zipping files cause them to be of lower quality?

WinZip compression is lossless. When you extract the files in a Zip file created by WinZip, the result will be exact, byte for byte duplicates of the original files. There is no loss of fidelity, no loss of image quality, and no change in data associated with zipping or unzipping. In fact, WinZip's default setting will preserve extended time stamps so that the files you zip and unzip will have the same Modified, Created, and Accessed date and time.
