PNG vs JPG

PNG uses lossless compression, so it preserves every pixel perfectly. JPG uses lossy compression, which discards some data to achieve smaller files. For photographs, the quality difference is often imperceptible, but for graphics with sharp edges and text, PNG is noticeably better.

PNG uses lossless compression, meaning no data is discarded. JPG achieves smaller files by removing visual information the human eye is unlikely to notice. This makes JPG files typically 50-80% smaller than equivalent PNGs for photographs.

Converting PNG to JPG will introduce some quality loss because JPG uses lossy compression. However, at high quality settings (90-95%), the difference is usually imperceptible for photographs. Note that transparency will be lost since JPG does not support it.

It depends on the content. Use JPG for photographs to keep page load times fast. Use PNG for logos, icons, and graphics that need transparency or crisp edges. For the best of both worlds, consider WebP which offers better compression than both.

Standard PNG does not support animation. However, APNG (Animated PNG) is an extension that does support animation with full alpha transparency, though browser support is more limited than GIF.

Consider WebP or AVIF for modern web projects — they offer better compression than both PNG and JPG. Use SVG for logos and icons that need to scale. Use GIF or WebP for animated content.
