Una comparativa detallada de Word Document (Legacy) y OpenDocument Text — tamaño de archivo, calidad, compatibilidad y cuál elegir según tu flujo de trabajo.
Word Document (Legacy)

Sobre los archivos ODTComparativa de ventajas
DOC Ventajas
- 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.
ODT Ventajas
- Truly open standard — ISO/IEC 26300, vendor-neutral.
- Native format of LibreOffice and OpenOffice, two of the largest FOSS projects.
- Human-readable XML, easy to script and parse.
- Preferred by many governments for archival and public records.
- ZIP compression keeps files compact.
Limitaciones
DOC Limitaciones
- 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.
ODT Limitaciones
- Microsoft Word support exists but subtly breaks formatting when round-tripping.
- Less common outside the FOSS ecosystem — most business workflows default to DOCX.
- Fewer third-party tools than for DOCX.
- Complex spreadsheet-like embedded content may not round-trip perfectly.

Preguntas frecuentes
DOC is the legacy Microsoft Word binary format used from 1983 to 2007, storing text, images, formatting, and embedded objects in the OLE Compound File container since Word 97. It was replaced as default by DOCX in Office 2007 but remains widely used in legacy archives and older government systems.
DOC files open in every Microsoft Word version from 1997 onward, Google Docs (free), LibreOffice Writer (free), Apple Pages, and most online viewers like OneDrive and Dropbox preview. On iPhone and Android, Word apps open DOC natively.
Use KaijuConverter's DOC-to-PDF converter for a single-click conversion. Microsoft Word, Google Docs, and LibreOffice all export to PDF natively via "Save as PDF" or the print menu — the result is identical and preserves every font, layout, and image.
Always DOCX for new documents. DOCX files are 75% smaller thanks to ZIP compression, follow the ISO/IEC 29500 standard, and support every modern Word feature. DOC is essentially a legacy compatibility format — Microsoft stopped improving it in 2007.
Older DOC files could contain VBA macros that became a common malware vector in the 2000s. Modern Office blocks macros by default. If you receive a suspicious .doc, open it in Google Docs or LibreOffice first — both strip macros automatically during import.
Yes. Open the .doc in Microsoft Word and use Save As → Word Document (.docx). LibreOffice Writer offers the same export. Formatting transfers cleanly in 99% of cases; complex features like some legacy form fields may need minor manual fixes.
