PNG files are often unnecessarily large for photographs and web images. JPG uses lossy compression that can reduce file sizes by 80-90% with minimal visible quality loss. This makes your images faster to upload, share, and load on websites. Converting to JPG is essential for web optimization and reducing storage space.
