What is a key limitation of JPEG images?

Explanation:
JPEG uses lossy compression, which discards some image data to reduce file size. When compression is strong, the lost information can't be recovered, so fine details disappear and you can get artifacts like blockiness and blurred edges. That degradation is the key limitation of highly compressed JPEGs. JPEG is a raster format, not a vector one, so it isn’t scalable without quality loss, and it does not support transparency because there’s no alpha channel. It cannot preserve original data perfectly, which is why heavy compression means lower image quality.
