Are you unable to upload or share image files through online forms, email, social media, or the web because they exceed size requirements? Imagine trying to send cherished holiday photos through an email only to have them rejected because they’re too large. Or consider wanting to post a high-resolution picture on Instagram, but the file size is just too cumbersome.
