NAPLPS

NAPLPS Strengths

  • Extremely bandwidth-efficient, enabling colorful graphical interfaces over early 300 baud dial-up connections
  • Resolution-independent vector scaling allowed the exact same file to be displayed accurately on varied early PC monitors and television sets
Limitations
  • Completely obsolete and unsupported by modern web technologies
  • Relies heavily on stateful parsing and terminal emulators rather than straightforward file decoding
  • Easily misidentified by MIME sniffers as plain text or generic binary streams due to the lack of a standardized file header
WebP

WebP Strengths

  • Superior lossy compression — 25–35% smaller than JPEG at equivalent quality
  • Supports both animation and full alpha transparency
  • Lossless mode available with smaller file sizes than PNG
Limitations
  • Slower encoding than JPEG, especially for lossless
  • Not supported in Internet Explorer or very old browsers
