doc2pdf

A command-line tool to convert WPS / Microsoft Office documents (.doc/.docx) to PDF.

Features

• No printer driver required — Uses COM automation to call the native export API of WPS / Office
• Auto-detection — Prefers WPS, falls back to Microsoft Word
• Page range support — Specify start/end page numbers
• Lightweight — Single exe, no external runtime dependencies (static link /MT)
• 32/64-bit compatible — 32-bit build recommended for maximum WPS/Office compatibility

How It Works

Uses COM automation to invoke the application's ExportAsFixedFormat API, no middleware or virtual printer needed.

Compatibility

Application	ProgID	Requirements
WPS Office (recommended)	KWps.Application	WPS Office installed
Microsoft Office Word 2007	Word.Application	Requires SP2 or Save as PDF add-in
Microsoft Office Word 2010+	Word.Application	Native support, no additional components
Microsoft Office 365	Word.Application	Native support

Startup order: tries WPS first → falls back to Office Word → exits with error if both fail.

Usage

doc2pdf <input file> [-o output file] [-f from page] [-t to page]

Argument	Description
-o / --output	Output PDF path (default: input file name with .pdf extension)
-f / --from	Start page (default: page 1)
-t / --to	End page (default: last page; requires -f)

Examples

doc2pdf 1.docx                      # All pages
doc2pdf 1.docx -f 2 -t 5           # Pages 2-5
doc2pdf 1.docx -f 3                # From page 3 to end
doc2pdf 1.docx -o D:\out.pdf       # Specify output path

Build

Requirements

• Visual Studio 2022 Build Tools (or full VS)
• CMake 3.10+

Build (32-bit, static link /MT)

cmake -G "Visual Studio 17 2022" -A Win32 -B build
cmake --build build --config Release

Output at build\Release\doc2pdf.exe, no VC runtime dependencies.

Architecture Notes

The tool is compiled as 32-bit and uses COM to call WPS/Office. A 32-bit tool can only call 32-bit WPS/Office (the most common installation on 64-bit systems).

To support native 64-bit Office, also build a 64-bit version with -A x64:

cmake -G "Visual Studio 17 2022" -A x64 -B build64
cmake --build build64 --config Release
