When to use Image Size Increaser (KB / MB)
Some portals need a minimum file size, for example at least 200 KB. Enter the exact size in KB or MB and the tool pads the JPG to exactly that many bytes with invisible data so the file reaches that size without changing how the picture looks.
The best image settings depend on where the picture will be used. Pixel dimensions describe width and height; file size describes bytes. Changing one does not guarantee a particular value for the other. Keep the original, compare the result at its intended size, and choose a format accepted by the destination.
