PhotoShop and Snagit. These two tools might be the most common tools for a graphic designer.

I use smush.it, RIOT, PNGOUT and the online optimizer from dynamicdrive.

Any version of Adobe Photoshop is the best for image optimization.

The unfortunate reality is that, no matter how carefully you design your images, the graphics tool you're using will not save the finished files in the most efficient way. And so passing those images through a compression tool can reduce their size considerably.

There are a lot of graphic design software available.but Adobe Photoshop is best for make any design because Photoshop is easy to use and provided great features.

We checked the programs for other issues, too. Were they easy to use? How fast was the compression process? And how reliable? Could a program sometimes increase an image size, for instance?

One of the easiest ways to reduce page response times is by optimizing your website images to reduce their file sizes as much as possible. Optimizing images not only makes your web pages load faster, but also reduces your bandwidth consumption, which can translate to significant savings in your hosting bills.

Adobe Photoshop. I recommend definitely with well functionalities. I have also tried it many times and using now too. go with it.
