RTFからPDFへの変換について

RTF (Rich Text Format) is one of the oldest cross-platform document formats, created by Microsoft in 1987 as a way to share formatted text between different word processors. While RTF served that purpose admirably for decades, it has significant limitations in the modern document workflow: inconsistent rendering across applications, no password protection, no digital signatures, and no guarantee that the recipient sees the same layout you created.

Converting RTF to PDF locks your document into a fixed, portable format that renders identically on every device, operating system, and PDF viewer in the world. Our converter uses a full office-document engine to parse the RTF markup — fonts, paragraph styles, tables, embedded images, headers, and footers — and produce a standards-compliant PDF/A output that preserves every formatting detail.

The conversion is particularly valuable for legal documents, academic papers, and business correspondence where layout fidelity matters. An RTF file that looks different in Word versus Google Docs versus LibreOffice becomes a PDF that looks exactly the same everywhere.

RTFをPDFに変換する理由

RTF's biggest weakness is rendering inconsistency. Because RTF is an editable format interpreted by the viewing application, the same file can look different depending on which word processor opens it. Fonts substitute unpredictably, table widths shift, and page breaks move. PDF eliminates all of these variables by embedding fonts and fixing layout at the point of conversion.

Security and professionalism are another key driver. PDFs can be password-protected, digitally signed, and set to read-only — features RTF completely lacks. When you send an RTF document, the recipient can edit it freely (often accidentally). A PDF clearly signals that the document is final and authoritative.

Archival compliance often mandates PDF as well. Legal filings, government submissions, insurance claims, and academic repositories typically require PDF format. RTF files are not accepted by most electronic filing systems. Converting to PDF satisfies these requirements while preserving the document content and structure faithfully.

主な活用例

  • Convert legal documents from RTF to PDF for electronic court filing
  • Archive old RTF business correspondence as fixed-format PDF files
  • Send formatted resumes and cover letters as professional PDF attachments
  • Lock down editable RTF reports into non-editable PDF for distribution
  • Prepare RTF academic papers for PDF-only journal submission systems
  • Convert RTF templates to PDF for standardized client-facing documents

仕組み

LibreOffice's document engine parses the RTF specification (version 1.9.1) completely, handling character formatting (bold, italic, underline, strikethrough, superscript, subscript), paragraph formatting (alignment, indentation, spacing, tab stops), tables with merged cells, embedded images (BMP, WMF, EMF, JPEG, PNG), headers and footers, footnotes, page numbering, and bookmarks.

The PDF output uses the PDF 1.7 standard with optional PDF/A compliance for archival. Fonts referenced in the RTF are embedded in the PDF (or substituted with metrically equivalent alternatives), ensuring text renders correctly even if the recipient's system lacks the original fonts. Table layouts are preserved precisely, and images maintain their original resolution without recompression.

品質とパフォーマンス

RTF to PDF conversion is essentially lossless for document content. All text, formatting, and images are preserved accurately. The only potential difference is font substitution: if the original RTF uses a proprietary font not available on the conversion server, a metrically similar substitute is used. Standard fonts like Times New Roman, Arial, Calibri, and Courier are always available and embed correctly.

最良の結果を得るためのヒント

  • 1Embed all fonts in your RTF before converting to ensure perfect font rendering in the PDF
  • 2Check page margins in the RTF — LibreOffice respects the margins set in the document, not system defaults
  • 3For legal filings, verify the output against formatting requirements after conversion
  • 4Use landscape orientation in the RTF if your tables are wider than portrait margins allow
  • 5Add page numbers in the RTF header/footer before converting — they carry over to the PDF

よくある質問

Yes. Fonts, bold/italic/underline, tables, images, headers, footers, and page layout are all preserved. LibreOffice accurately interprets RTF formatting and reproduces it in PDF.
RTF files do not support password protection natively. If your RTF is inside a password-protected ZIP, extract it first, then convert. You can add password protection to the resulting PDF if needed.
RTF is an editable format interpreted by each application differently. Font substitution, margin handling, and table rendering vary between Word, Google Docs, and LibreOffice. PDF eliminates these inconsistencies by fixing the layout permanently.
Free users can convert RTF files up to 50MB, which covers virtually any document. Even extremely long RTF files with many embedded images typically stay under 20MB.
Yes. Tables with merged cells, borders, and shading convert accurately. Embedded images (BMP, JPEG, PNG, WMF, EMF) are preserved at their original resolution in the PDF output.
Our converter produces standard PDF 1.7 output by default, which is widely compatible. The output is also suitable for most PDF/A archival requirements since fonts are embedded.
Most documents convert in 2-5 seconds. Very long documents with hundreds of pages and many images may take 10-15 seconds. The processing is handled server-side using LibreOffice.
Yes. Hyperlinks embedded in the RTF are preserved as clickable links in the PDF output, maintaining navigation within the document and to external URLs.
Yes. Upload multiple RTF files and convert them all to PDF in a single session. Each document is processed independently and downloadable separately.
