Well...it depends on what app you're using. Some are very convenient to work with. It's even easier for me to do the editing in one app and paste wherever I want. I edit my photos in https://depositphotos.com/upscaler.html all the time. This`s where I finally found the freedom of choice. Before I had to crop photos to certain proportions, but now I can crop whatever I like. The quality of the photo is the same, and I can`t think of any other app that does the same for image preservation. In addition can say - here you`ll find simple menu which is easy to understand and bunch of useful functions=)
