Does Google chrome affect the quality of a picture?

[uchka]

so you guys obviously do know that by using Google chrome you can download a picture from the internet by dragging it to your desktop right? i was just wondering about when i drag a picture from Facebook or from Google images etc, would the quality of the picture be affected?
what i usually do to get pictures from my phone to my laptop is that i upload the picture to Facebook and drag it to my desktop my using Google chrome, but for some reason i think that when i do this, the quality of my picture gets worse. Would it be better if i send the photo to my email and download it rather than uploading it to Facebook and dragging it? does it make a difference?
