A 64-bit PC can handle larger amounts of information than a 32-bit system. Since it can use more RAM—4 GB and up—a 64-bit computer can be more responsive when you’re running lots of programs at once. Still, having a 64-bit OS doesn’t automatically make all applications faster because much of today’s software is written and optimized for a 32-bit era. You’ll need software specifically optimized for 64-bit processing to take advantage of any speed improvements. ImageConverter Plus has been fully optimized to run on Windows 7 64-bit OS. Still, you will hardly see the difference except when working with really huge image files. The image size needs to be 120000×120000 pixels for you to require and really appreciate the 64-bit system.
