  1. Awesome resources for online image compression and I guess all of them are totally new to me. I’d surely try them out.


  2. I tried to compress my images on many online sites but it wasn’t worth it ,
    ur info was very much helpful ………………….. this sites really works

    thanks for posting

  3. Hi Shiv, thanks for writing this article. It helps a lot to get good score in the insights. Plus you can also reduce the size of your website making it easier to take backups and move. Really a good source of info.

    But I would like to add one more easy and probably the best way out.
    Every one has Photoshop, why not use the option “Save for Web”. It actually works fas better than online tools and you can customize the way you compress images. For me its fantastic. If you try it once, I bet you’ll not use these online tools anymore.

    Again if considered for those who don’t have Photoshop, its the best option said by you.

      Hi Shashank,

      Welcome to STL!

      You are right! Even for offline purpose I use photoshop. But as you said, ‘Every one has photoshop’… I agree but not everyone has photoshop due to some reason like everyone don’t know to use photoshop so they won’t install photoshop just for compressing image, installing photoshop occupy space in the system and even require more RAM memory while running as compare to other application. So, it’s not a good decision for everyone to install photoshop just to compress image.

      But everyone has browser so that they can access this online tool which don’t even occupy memory in the system hence, I think it is handy and efficient for everyone.

      But yes for those who has photoshop installed in their system can use photoshop as suggested by you.
      Thanks for adding information to my post.

      Thanks for stopping by and sharing your view. 🙂

      1. Shiv, Thanks for the welcome. I totally agree with you, but I have to ask only one question.

        You are a webmaster and you don’t know how to use a simple application? Would it not be a type of shame? 😛

        If some of its really don’t know then it’s great idea to use these online tools. Thanks

          Hi Shashank,

          Glad to see you again.

          I think you had misinterpreted my reply.

          I have mentioned in my reply that I use photoshop for my offline purpose.

          And this post is not only for webmasters it’s for everyone which include non-webmaster .

          And if anyone don’t know to use photoshop then I think it’s not a type of shame for them because they might be better than us in other area… for which I respect their skills.

          Thank again for coming by and asking your question.

          Hope to see you again. Have a great day! Bro.. 🙂
