    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.

    You caan try this powerfull onilne tool a png/jpg/gif image compressor which allows you to compress 50 files at one go without any restrictions.I am currently using this and it has benefited me in a lot of ways.

    Firstly you can reduce or shrink the image by 70-80% of the total kb. You can easily avoid the use of plugins as we all know that it increases the load on the webiste .So this is another advantage you can enjoy to speed up your website.

    Another feature which i enjoyed is to reduce any ppt file in the same way.

    With the help of this tool you can also change the colors of the image using the existing colors making no noticeable changes in the eyes of the viewers.

    So enjoy a faster compression and optimization tool and share your experiences.
