How do I drastically reduce the size of the JPEG? - eru777 - 09-11-2021
I take photos daily of items for an estore. They are a big size, and I'd like to reduce it.
I tried to reduce the quality, but the size is still big. Do you have any ideas?
I reduced the dimensions but I would like to further decrease the overall SIZE, not just the dimensions.

The first thing to consider is the image size in pixels. You camera likely produces image in the 10-20Mpx range while you website needs images that are around 2MPx (1000-1500px to a side, close up views) or even 0.5MPx (500-700px to a siden, "catalog" views). Everything else being equal (format, compression ratio) the file size is roughly proportional to the image size so by scaling down the images to adequate size you have a 5x minimum reduction in file size (and possibly much more).
