Limitations

−3–5× larger than JPG for photographic content

−No native animation support in standard PNG

−Slower to load than WebP for equivalent image content

−Not practical for very high-resolution photographs at web scale

Logos, icons, and brand marks placed over any background colorScreenshots where text must remain perfectly sharpImages edited in multiple passes (keep as the master file)Web UI elements, buttons, icons, and interface assets

Limitations

−Lossy — permanently discards image data with every save

−Visible block artifacts on sharp edges, text, and high-contrast areas

−Quality degrades with each re-save (generational quality loss)
