Imagine you are uploading a profile picture, designing a website, or saving a graphic for a project. You see two familiar file options: PNG or JPG. Both formats are widely used, but choosing the wrong one can affect image quality, loading speed, and storage space.
People often confuse PNG or JPG because both are image file formats used for digital pictures. However, they are designed for different purposes. PNG focuses on preserving image quality and supporting transparency, while JPG is designed to reduce file size through compression.
This guide explains the difference between PNG OR JPG, how each format works, when to use each one, and which image format is better for different situations.
