How do you differentiate between JPEG and PNG?

JPEG and PNG are both image formats, but they have key differences. JPEG (Joint Photographic Experts Group) is best for photos with many colours and smooth gradients. It uses lossy compression, which reduces file size but can lower quality. PNG (Portable Network Graphics) is ideal for images needing transparency or with sharp edges and text, like logos. PNG uses lossless compression, keeping all image details without quality loss, but files are usually larger. Use JPEG for detailed photos and PNG for images needing clarity or transparency. Based on the years of experience of the Website designing company in Delhi, you should know which format should be used and where.
