About DOC to PDF Conversion
DOC (introduced 1983) and PDF (introduced 1993) are both document formats, but they differ in important ways. DOC is the legacy Microsoft Word format (pre-2007) — still widely circulated. PDF (Portable Document Format) preserves layout, fonts, and graphics across every device and operating system.
Full Name: DOC uses Microsoft Word Legacy, while PDF uses Portable Document Format. Compression: DOC uses None (uncompressed), while PDF uses Lossy & Lossless. Typical File Size: DOC uses 50 KB–10 MB, while PDF uses 100 KB–50 MB (depends on embedded graphics).
