    I believe it’s important to note that Photoshop is a great option as well if you have it. It makes quality selection and file type alteration easy.

    An additional note for this topic would be when to use which filetype:
    .png (8bit) and .gif are good for logos, illustrations and text that have flat colors.
    .png (24bit) is for higher quality illustrations that require more detail.
    .jpg is for photos (example: A picture of a product) – .jpg can’t manage transparencies but the rest can

    Making sure you’re using the right filetype for your images is also important in optimizing their filesize since using the wrong type will inflate the size.

    Great article, Sig.

    What’s your thoughts on turn-key shopping cart platforms like Shopify? Do they automatically optimise their clients’ images? Or do you need to use these tools as well?

    • Sig Ueland July 30, 2014 Reply

      Thanks, Elizabeth! Shopify does automatically compress images. However, merchants should always test load times as part of their image optimization checklist. As Mitchell noted, this checklist should also include verifying correct file types and creating keyword-rich file names.

    It was good to know about these tools. Even people must have some idea on image optimzation. Here are other few things to be known –
    1. naming the images
    2. Optimizing alt tags
    3. Strategize image dimensions & product
    4. Reducing the file size
    5. Know which file to use and much more.

    Hi There seems to be a problem with RIOT image optimizer, whenever I try to download it I get an “Access Denied” message with a virus warning.
    Do you know where I can download a clean version?
    Thanks

    Very useful resources, you can also use an online css sprite generator to combine multiple images into a single one, then optimize this images with these programs you listed, another good online image optimizer is http://resizeimage.net/

    The most complete list, a lot to test :) TinyPNG algo tested so far is quite impressive for PNG. Now there’s serious competitors on the market like Wp smush, ImageRecycle with PDF compression too (www.imagerecycle.com)
