How to get rid of pixelated images in illustrator?

Question

Adobe Illustrator

Hello!
I'm making up a catalog in illustrator, I need to insert photos.
I insert an image with the already set physical size and resolution (300dpi), the edges of the original are smoothed. In the document, the image is disproportionately large, you have to scale it. When scaling, pixels appear at the edges of the image.

Obviously, there must be a solution to this issue.

It's very simple and stupid, I recently learned it myself:
Select your image -> Effects -> Rasterize -> Options -> Art optimized (supersampling)
That's it. The effect is hung on the object and is available from the appearance panel - there you can toggle it, observing the awesome difference in quality.
