What is the best method to reduce image size minimizing resolution loss?
Let me ask a question that I thought I knew, but now I'm doubting myself.
I routinely take photos from my iphone (either jpg or heic format) and put them on a web page. The photos are normal size, say 4000x3000 pixels. I have been reducing the width to 1200 pixels for the web, using Preview, with the Scale proportionally and resample image options selected. However, lately I have observed when zooming in after this reduction, there is a lot of loss in the resolution compared to the original. Now perhaps this is common logic, and perhaps I should just post the full size image, but I wanted to ask the community: Is there a better way for posting images on a website?
