Understanding JPG and PNG
- JPG (JPEG): Great for photographs and images with many colors. Uses “lossy” compression (some quality is lost) for smaller file sizes.
- PNG: Ideal for images with sharp lines, text, or where you need transparency. Uses “lossless” compression (no quality loss).
Why convert?
- To use PNG’s transparency features.
- To reduce file size slightly (if the quality loss of JPG is acceptable).
- To meet specific file format requirements of websites or applications.
