PNG Ventajas

  • Lossless compression — every save preserves the original pixels perfectly.
  • Full 8-bit alpha channel for smooth transparency.
  • Excellent for text, UI screenshots, logos, and line art.

  • Metadata capabilities are less rich than JPEG's EXIF.

XBM Limitaciones

  • 1-bit monochrome only.
  • Legacy — modern UIs use PNG/SVG.
