An image file size is proportional to the AREA of your picture. So, look at the present file size in Mb. Take the square root of that number, then divide it INTO either the length or width of the present picture. That should be your NEW width or Height. Then take whatever graphics program you are using and in the resize function, enter the new width or height. Make sure you have the box on that page marked %26quot;Keep same aspect ratio%26quot; ticked.
Even the simplest calculator has a square root function. If not use Excel. Assume the file size is 2.56 Mb, then square root formulas would be
=2.56^0.5 and hit enter where the ^ is above the number 6 key (It's called a caret)
