Sobre os arquivos PNGComparativo de vantagens
DOC Vantagens
- Universal compatibility — every Word version since 1997 reads it natively.
- Rich feature set: styles, tables, comments, track changes, embedded OLE objects.
- Binary format means fast loading even on slow machines.
- Well-understood after decades of reverse-engineering — dozens of parsers exist.
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
DOC Limitações
- Legacy format — Microsoft stopped improving it in 2007; new features require DOCX.
- Binary structure is fragile; corruption often makes files unrecoverable.
- Historic malware magnet: embedded macros have spread viruses since the 1990s.
- Not open-standard — DOCX is the ISO-standardized successor.
- Subtle formatting drifts when opened in LibreOffice or Google Docs.
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.
