Images play a crucial role in articles and blogs. People find it easier to read content that includes more images. Long, boring text can be a turn-off, right?

Images are also attention-grabbing. People may skip over sentences or phrases, but they can’t ignore captivating images.

However, having too many images on your blog can slow down its loading time and increase the bounce rate. This can negatively impact your blog’s SEO. In such cases, you’ll want to consider photo editing and compressing your images.

Keep in mind that simply resizing your images to medium, large, or thumbnail sizes won’t effectively reduce their file size.

  1. Hello Aditya !!

    Tiny PNG is my favourite .
    Also , one should remembers to reduce the dimensional size of the pictures and then compress them .

    This is because , when browser loads the pictures , it loads them in their original size and then finally changes them to the size as the blogger has defined . This reduces the page speed as well .

    Great work again !

    Best of luck !!
    Regards !
