Hello, does Illustartor have the function "gradation curves" also like Photoshop, or at least a function how to increase the resolution of an image with three or more colors? I want to make the resolution of my logo as high as possible.

Greetings

    Illustrator is a vector based program, so resolution isn't something that is really used other than when you are using raster effects in the document. You set up raster effects when you define the document under the advance settings (see image below). But I think the real question is how is the ultimate image being used and what is the export settings for that document? That might be where you are having the problem.

    Gradation curves doesn't alter the resolution of a file. Not even in Photoshop.

    If your logo is a pure vector file, there's no need to worry about resolution.

    In short: I want to insert a normal image from my PC into Illustrator. It's an image from the Internet. I paste it into Illustrator, but when I zoom in, it's pixelated. How can I improve the quality of the image with Illustrator?

    You can only have the resolution that the image from the internet was saved as. So if you downloaded something, you could open it in Photoshop and look at Image Size to see the pixel dimensions, width and height. So for example if it's 800px wide by 600px tall, fairly common on blogs, that's the max resolution of that file.

    In Photoshop you can increase the resolution a little but if you do more than 10% you will start to see interpolation (reprocessing artifacts) that won't look good.
