Resizing issues, loosing quality, getting pixelated

[Tanisha5E8C]

Hi guys, I have been asked to provide image ads to our google marketing person in the sizes below (in pixels)

1 x  600 x 316

1 x  300 x 300 

1 x  314 x 314

It also says recommended: 1200 x 628

max file size 5,120KB

The issue im having is, all the images of product and product cut out we have are all professional camera quality images that are large, and whenever I try to resize on photoshop, the images get extremely pixelated...it looses quality and is pixelated.

How do I fix this issue? How can I shrink my images without loosing quality?

Shall i try it on Illustrator or any other program instead?

Hi,

From what I see on the attached images yoyu provided, your image isn't "extremely pixelated", just slightly.

What zoom level are you looking at the image at? Because if you zoom in to more than 100% view,  the image will look pixelated.

300 pixels is thumbnail size. There's no way to get high quality from images that small.

At 100% you see one image pixel represented by exactly one physical screen pixel. If you zoom in beyond that, all you will see is pixels. Don't zoom in above 100%.

In other words, everything here is normal and expected.

You need to accept that these images are very small, and optimize for 100% view.

Try to resize the large photo to about half the size. Then reduce again to a smaller size after saving the new smaller size. See if that helps.

or save as a pdf. Than open the pdf in photoshop and resize photo at that time.
