DOC vs HTML
Ein detaillierter Vergleich von Word Document (Legacy) und HTML Document — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
Word Document (Legacy)
Documents & TextDOC is the legacy binary format used by Microsoft Word 97-2003. While superseded by DOCX, many archived and legacy documents still use this format and require conversion for modern editing.
Über DOC-DateienHTML Document
Documents & TextHTML is the standard markup language for web pages. As a conversion target or source, it carries text content with structural and formatting information that can be extracted or repurposed.
Über HTML-DateienVorteilsvergleich
DOC Vorteile
- 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.
HTML Vorteile
- Universal — every browser, OS, email client, and document reader displays HTML.
- Plain text, human-readable, grep-able, and diffable in git.
- Flexible — pages render even with broken or partial markup (error-tolerant parser).
- Carries structure, styling (CSS), and behavior (JavaScript) in one file.
- Accessibility-friendly when written with semantic tags and ARIA attributes.
Einschränkungen
DOC Einschränkungen
- 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.
HTML Einschränkungen
- Error tolerance allows sloppy markup to hide real bugs.
- Rendering depends on browser engine — pixel-perfect cross-browser output is an art form.
- Security-sensitive — unsafe HTML can execute scripts or leak data (XSS vulnerabilities).
- File size for equivalent structured data is larger than JSON or XML due to tag verbosity.
- No built-in typing or schema — contract between server and client is informal.

Häufig gestellte Fragen
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.
