About Word files
Word documents are saved as DOCX, or as DOC in older versions of Microsoft Word. They are made to be edited, so the layout can shift when the file opens in another app, another version or on a phone.
People convert Word to PDF to lock the layout before they send a CV, an invoice, a thesis or a form. A PDF looks the same for every reader and cannot be changed by accident.
How we convert Word to PDF
- Engine
- A full office-document engine lays out each page, then writes the PDF.
- Accepted files
- DOCX and older DOC files.
- Compression
- Four presets for the PDF: Maximum, High (the default), Medium and Minimal.
- Page size
- A page size option lets you set the size of the PDF pages.
- Measured
- A one-page DOCX of 5.6 KB became a 23 KB PDF in about 5 seconds.
Common problems and fixes
A font in the PDF looks different from the one in Word.
The document uses a font that is not embedded in the file. In Word, turn on the option to embed fonts when you save, then convert again.
The PDF is larger than expected.
Large photos inside the document take most of the space. Choose the Maximum compression preset, or compress the images in Word before you convert.
Page breaks moved.
Word and other layout engines can place long tables and images a little differently. Add a manual page break before the section that moved and convert again.

DOCXからPDFへの変換について
Converting Microsoft Word documents to PDF is the most common document conversion in the world. Every day, millions of resumes, contracts, reports, invoices, proposals, and academic papers are converted from Word to PDF for sharing, archiving, and printing. PDF preserves the exact visual layout of the Word document (fonts, formatting, images, tables, and page breaks) in a fixed-layout format that looks identical on every device, every operating system, and every printer.
This conversion accepts any Microsoft Word document: DOC, DOCX, files from Office 365, Google Docs exports, or any other Word-compatible application. The output is a standards-compliant PDF that opens in every browser, on every phone, and in every PDF reader, with fonts embedded to guarantee consistent rendering regardless of what software the recipient uses.
DOCXをPDFに変換する理由
PDF is the universal standard for document sharing. Unlike Word documents, which can render differently depending on the viewer's Word version, installed fonts, and operating system, PDF files look identical everywhere. When you send a resume, the recruiter sees exactly what you designed. When you submit a contract, the other party sees the precise formatting you intended. This consistency is why PDF is mandated for legal filings, academic submissions, and professional document exchange.
PDF also prevents casual editing. While not a true security measure, PDF requires specialized tools to modify text, unlike Word documents that can be opened and changed by anyone with a word processor. For professional documents where content integrity matters, PDF provides a practical read-only distribution format.

仕組み
Our office-document engine renders the Word document using its comprehensive layout engine, which handles both DOC (OLE2 binary) and DOCX (OOXML) formats. The document is rendered page-by-page, and each page is serialized to PDF using the engine's PDF export filter. Fonts used in the document are subset-embedded in the PDF to guarantee consistent rendering without requiring the recipient to have the fonts installed. Hyperlinks are preserved as clickable PDF links. The output PDF is ISO 32000-1 compliant. Bookmarks are generated from Word heading styles for PDF navigation.
品質とパフォーマンス
Word to PDF conversion is virtually lossless for standard documents. Text, formatting, images, tables, headers, footers, footnotes, and page layout are reproduced with pixel-level accuracy. Fonts are embedded, ensuring the PDF looks identical to the Word original regardless of the viewer's system. Complex Word features (embedded Excel charts, SmartArt, WordArt) are rasterized to their visual appearance. Track changes and comments can be included or stripped based on preference.

最良の結果を得るためのヒント
- 1Use Word's built-in styles (Heading 1, Heading 2) for consistent conversion and to generate PDF bookmarks automatically
- 2Ensure all images in your Word document are at the resolution you want: the PDF keeps whatever resolution the images have
- 3Review the PDF on a different device after conversion to verify fonts and layout render as expected
- 4For legal documents, verify page breaks and paragraph numbering in the PDF match the Word original exactly
- 5If file size matters, reduce image resolution in your Word document before converting, because images make up most of a PDF's size
