Why do images lose quality when enlarged?
Resizing an image enlarges or shrinks each of the pixels inside the image. When you shrink the pixels, you see no loss of quality in the image, because the pixels become even less visible. However, when you enlarge an image, the pixels become more visible and their mapping becomes more pronounced.
What happens to an image if you resize it with resampling selected?
This is the option that determines whether we’re resizing our image or resampling it. Again, resizing keeps the pixel dimensions (the number of pixels in the image) the same and simply changes the size at which the image will print, while resampling physically changes the number of pixels in the image.
How to resize an image without losing quality?

What happens when you resample an image in Photoshop?
This process is called resampling. When you scale an image even by a single pixel, the entire image is resampled or rewritten. This is why creating the image at the correct size in the first place is great. However, don’t fear, Photoshop does a really great job of resampling and many times you will never be able to see the difference in quality.
What’s the difference between resampling and resizing pixels?
When it comes to manipulating pixels there are actually two methods, resizing and resampling. Resizing is the most basic as it simply enlarges or decreases the size of the pixels to whatever scale is desired. Thus, its other name, scaling. Resampling is slightly more complicated.
What happens when you enlarge an image in Photoshop?
The problem with sampling up (enlarging) is that you will lose image quality. The larger you make it, the more quality you will lose. If you need to scale the image down (reduce) then the quality loss isn’t so much as issue, although you may need to sharpen an image if you shrink it too much (more about that soon).
