In Photoshop, what's the difference between Save (or Save As) and Export?
The question arises because "Save as" and "Export" shares several options for the file destination's format.
So, when I should use "Save as" and when "Export"?
Here's how I look at these two options when I'm working in Photoshop...
"Export" is my method for saving a file that needs to be optimized for transmission over a low data-rate medium (like the internet). Adobe explains the "Export" feature like this...
"A redesigned exporting experience lets you export a single layer, artboard or entire document with one click. Plus, get better compression, advanced preview options that include canvas size and enhanced asset extraction. Itâ€™s a modernized Save for Web experience."
"Save As" is my standard method for generating final image files in a variety of formats (including some that are available in "Export"), while retaining maximum file information and metadata. When I'm using "Save As" I'm primarily interested in retaining a file with the best quality (in a particular format), not reducing/optimizing the file size.
