Sobre os arquivos PNGComparativo de vantagens
GIF Vantagens
- Universal animation support — every browser, every chat app, every social network.
- Transparent backgrounds for compositing against any page color.
- Lossless for its limited palette — pixel-perfect at 256 colors.
- Self-contained: no codec, no browser plugin, no third-party player needed.
PNG Vantagens
- 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.
- Royalty-free and an ISO standard (ISO/IEC 15948).
- Supports 16-bit color depth for high-fidelity work.
Limitações
GIF Limitações
- Limited to 256 colors per frame — looks posterized on photographs.
- Dithering for color-rich images makes files huge (often 10× an MP4 equivalent).
- No audio track.
- Transparency is 1-bit (on/off) — no smooth alpha blending.
- Poor compression compared to modern formats (WebP, MP4, AVIF).
PNG Limitações
- 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.
