Einschränkungen

PNG Einschränkungen

Much larger than JPEG for photographs (no perceptual compression).
No native animation in most software (APNG support is inconsistent).
No CMYK support — web and screen only, not print.
Metadata capabilities are less rich than JPEG's EXIF.

Y4M Einschränkungen

Enormous file sizes.
Development-only — not for consumption.
No metadata beyond basic stream params.
