How can i adjust the dimensions of a photo without loosing it`s quality in photo shop or in any other tool.?

Question

by using any tool i want to adjust the photo in a specified size without loosing the picture quality.

Answer 1

You can always reduce the size without loosing quality, but no tool is able to enlarge a regular pic without it turning out pixelated. But you could turn your pic into a vector graphic which would indeed allow it to be saved in any size without any loss of quality.
