JPG vs PNG: Understanding the Difference

JPG and PNG are both popular image formats, but they serve different purposes:

Format Compression Transparency Best For File Size
JPG Lossy ✗ Not supported Photographs and web images Smaller
PNG Lossless ✓ Supports Graphics with text or transparency needs Larger

Converting JPG to PNG preserves image quality completely while adding transparency support, making it ideal for graphics, logos, and images that need to be edited further.

Quality Settings Explained

PNG format uses lossless compression, so quality is always preserved at 100%. The quality slider is shown for UI consistency but doesn't affect PNG output:

Quality Setting PNG Output Note
100% (Lossless) Perfect quality preservation PNG's default lossless compression
Any Setting (10-99%) Still lossless quality Quality parameter ignored for PNG
UI Consistency Same interface as JPG converter For familiar user experience
