The Practical Answer
Use JPG for photos. It produces much smaller files with acceptable quality for web use. Quality 80-85% is the sweet spot for most photographs.
Use PNG for graphics and transparency. When you need transparent backgrounds, crisp edges, or lossless quality, PNG is the right choice.
Consider WebP for web publishing. WebP provides 25-35% smaller files than JPG with similar quality and supports transparency. It is the modern standard for web images.

Frequently Asked Questions
Which is better, JPG or PNG?
Neither is universally better. JPG is better for photographs (smaller files, no transparency). PNG is better for graphics, logos, and screenshots (lossless quality, transparency support).
Why is PNG file size larger than JPG?
PNG uses lossless compression that preserves all image data. JPG uses lossy compression that removes some data for smaller files. PNG files are typically 2-5x larger than JPG for photographs.
Does JPG support transparency?
No. JPG does not support transparency. If you need transparency, use PNG or WebP.
