Document Format Comparison

PDF vs TIFF — Universal Document vs Multi-Page Image Format

PDF and multi-page TIFF both store multi-page documents as image-based files (when scanned). PDF is the universal modern standard; TIFF is the legacy standard for fax archives, medical imaging, and high-volume scanning systems. Modern document workflows almost always use PDF; TIFF persists in specific industries.

Quick Verdict

Use PDF when…

Use PDF for modern document workflows — sharing, archival, OCR, web display, e-mail attachments, and almost everything.

Use TIFF when…

Use TIFF for medical imaging (DICOM uses TIFF internally), fax archives (Group 4 TIFF), and high-volume scanning systems that haven't migrated to PDF/A.

Frequently asked questions

Should I convert TIFF archives to PDF?

Generally yes — PDF (especially PDF/A) is the modern archival standard with broad tool support. TIFF archives from old systems benefit from migration to searchable PDF/A for long-term accessibility.

Which has better quality for scans?

Effectively identical when both use high-quality settings. TIFF with LZW or ZIP compression is lossless. PDF can embed TIFF images losslessly. The choice is about workflow and access, not quality.
