    compressed Zip Folders

    The word 'zip' means compressed. So calling something a zip compressed folder is redundant ;-)

    The term originated with a very popular, old file compression program called Pkzip, which used the file extension .zip

    All photos lose data when compressed; some more, some less, depending on the photo's format. Most popular photo formats used today - like .jpeg - are already compressed, so compressing them further won't reduce their file size much.

    Here's something very important to know about compressing photos: Compression works by discarding redundant pixels - that's why the file size becomes smaller. Once discarded, those pixels can never be recovered, which means the quality of the image will
    suffer if you compress it too much or too often.
