PDFからTIFFへの変換について
TIFF (Tagged Image File Format) is the gold standard for archival-quality raster images in professional workflows. Used extensively in medical imaging, legal document management, publishing, and long-term digital preservation, TIFF supports lossless compression, multi-page documents in a single file, CMYK color spaces, 16-bit color depth, and embedded metadata. Converting PDF to TIFF produces the highest-quality raster output available.
The conversion rasterizes each PDF page at your specified DPI and stores the pixel data in TIFF format with LZW or ZIP lossless compression. Unlike JPEG, TIFF introduces zero compression artifacts. Unlike PNG, TIFF supports multi-page files, CMYK color, and the metadata standards (EXIF, IPTC, XMP) that professional workflows require.
PDFをTIFFに変換する理由
Legal and compliance workflows often mandate TIFF format. Court filing systems, insurance claims processing, medical records systems, and government archives frequently require TIFF because it is the de facto standard for archival document imaging. The FBI, IRS, and many federal agencies specify TIFF for document submissions.
Multi-page TIFF is the only common raster format that stores multiple pages in a single file, making it the natural choice for converting multi-page PDFs to images while maintaining the one-file-per-document paradigm. This is critical for document management systems that track files by document rather than by page.
主な活用例
- Convert PDF documents for court filing systems that require TIFF format
- Archive PDF documents as multi-page TIFF files for long-term digital preservation
- Prepare PDF pages for medical imaging systems that use TIFF as their standard format
- Create archival copies of PDF documents for insurance claims processing
- Convert PDF drawings to TIFF for engineering document management systems
- Submit PDF documents to government agencies that mandate TIFF format
仕組み
Ghostscript rasterizes each PDF page at the specified DPI (default 300) into an RGB or CMYK pixel buffer. The buffer is written to TIFF format using LZW compression (lossless) by default, with options for ZIP compression, CCITT Group 4 (for black-and-white), or no compression. Multi-page PDFs produce a single multi-page TIFF file where each page is stored as a separate TIFF directory (IFD) within the file. The output supports 1-bit (B&W), 8-bit grayscale, 24-bit RGB, or 32-bit CMYK color modes. EXIF and XMP metadata can be embedded.
品質とパフォーマンス
TIFF output is lossless — the rasterized page content is stored with mathematical precision, no compression artifacts, and full color fidelity. Quality depends only on the DPI setting: 300 DPI is standard for print-quality archival, 400-600 DPI captures fine detail in engineering drawings or small text, and 150 DPI is sufficient for screen display. The CCITT Group 4 compression option produces extremely small files for black-and-white documents (roughly 50 KB per page at 300 DPI).

最良の結果を得るためのヒント
- 1Use 300 DPI with LZW compression for the standard archival quality that most systems require
- 2CCITT Group 4 compression is dramatically more efficient for black-and-white documents — use it for text-only content
- 3Multi-page TIFF keeps all document pages in a single file, which is preferred by document management systems
- 4Verify your target system's TIFF requirements — some systems require specific compression types or color modes
- 5For CMYK output required by print workflows, specify CMYK color mode during conversion
