Why is an RGB jpg file 83 KB in Windows Explorer and over 6 MB in IrfanView? It's a one-page A4 black and white document scanned into CorelDraw. If I click on it and go to Export For Web and set it for jpg 100%, it gives me 1.87 MB. How can Explorer be soooo far off?
Are you looking at the number in IrfanView where it is showing you how large the image is when loaded into memory (rather than how large it is when stored on disk)?
Thanks for your prompt reply!
Yes. What is the difference between disk size versus current memory size?
The file stored on the disk can be smaller because the image has been compressed.
