    My website has gotten slow all of a sudden and I’m not sure if it has anything to do with all the photos for my listings. They’re mostly JPG. I was told to convert them all to PNG. Is that wise? Will it make a difference? Or is there a different culprit for the slowness?

    JPGs are usually smaller in size than PNGs. So that cannot be the culprit.
    Absolutely no need to convert to PNGs.

    Hi,

    I’m sure whoever suggested that meant the other way around. Convert your png into JPG.

    Example: http://www.yallu.com/wp-content/uploads/2014/09/648_The-French-Baker-1.png

    That image alone is over 500kb. You have 6 of them making the home page way too heavy (see screenshot).

    Also, some of your JPG are still a bit too heavy. You should use a image editor like photoshop to reduce their size or an online tool like smush.it.

    Here a guide to optimize images on your website: http://www.hongkiat.com/blog/jpeg-optimization-guide/

    Thx and let us know!

    Thanks, this helps a lot. What is the fastest why to swap out the big files with the newly compressed/modified ones for all the listings in bulk? I recognize removing each image then replacing with the new one per listing will require a lot of work/time.

    I understand, but that is the simplest way too.

    Another option would be to bulk delete all listings and reupload them via CSV with the new images names, if you have them already in a CSV file.

    In any case for you we are talking about less than 10 images…

    OK, great advice. I forgot there was the option to use a CSV file. That solves all my issues then. Thanks, Paolo!
