Why would I need to compress an image to exactly 2MB?
Many platforms and services impose a 2MB upload limit as a practical ceiling for user-submitted images. Social networks, marketplace seller portals, print-on-demand services and media submission platforms commonly use this limit. It also appears as the maximum attachment size for certain email servers and file-sharing tools. Modern smartphone cameras produce photos of 5MB to 15MB at default settings, so compressing to 2MB is often required.
