How to compress banner images without completely destroying the image quality?

So after running many different tests I have determined that one of the biggest factors that is causing my site speed to be so slow is my affiliate banners.

Naturally I immediately looked to compress these images, re upload them to my site, and use them.


FAILED - (93.1 KB, compressed = 17.9 KB - savings of 75.2 KB)

Above is an example of what my file size is, and what it should be. Spread that out across 4 or 5 banners and it's definitely doing some damage.

First what I attempted to do was save the banner, import it into photoshop, and export it at the lowest quality possible, and even doing that the image still was around 24KB in size. However, the quality was destroyed.

These images have a long way to go in terms of compression, so I'm curious if anyone knows of a way to do this without destroying the image quality. Some quality reduction will be inevitable I am aware, but they still need to be somewhat clean and HD.

Thank in advance!

Open it on Ps and save as for Web

RIOT is a free application that can be used to optimise images without using much quality at all - http://luci.criosweb.ro/riot/

Yes open your image at Photoshop and Save for Web and Devices (Ctrl+Alt+Shift+S). Also .png fie is more suitable.

Wow thank you for such quick responses!

I actually stumbled upon this site http:/ /compressjpeg. com/ and it seems to be doing the trick so far and not noticeably decreasing the quality. I may give that application a try too when I switch banners!

Thanks!
