If you convert the full-resolution JPEG/HEIC to PNG you won't lose any information, right?

Technically, you do lose _some_ information. PNG cannot represent DCT coefficients nor YCbCr data, and the conversion of those things to (8-bit) RGB is a (slightly) lossy operation.

Sure, but what's the advantage to blowing up the file size to losslessly preserve all the lossy artifacts from JPEG or HEIC?
