Should I scan to PDF or TIFF?

For most business purposes, PDF/A is the better choice — it supports searchable text (OCR), multi-page files, is smaller in size, and is universally compatible. TIFF is better for archival preservation where lossless quality is essential. Many organisations scan to TIFF as a master copy and create PDF/A versions for daily use.

Can I scan to both PDF and TIFF?

Yes, and many organisations do. Scan to TIFF-G4 as the master preservation copy and generate PDF/A with OCR for everyday use. Most professional scanning software outputs both formats simultaneously at minimal additional cost. The main consideration is storage — TIFF files are 3-10 times larger than PDFs.

PDF vs TIFF: Best Format for Scanned Records

PDF and TIFF are the two most common formats for scanned business records. Both are widely supported and suitable for long-term storage, but they serve different purposes. PDF is more practical for everyday use; TIFF is better for archival preservation. Understanding the differences helps you choose the right format — or decide to use both.

PDF for Everyday Use

PDF (Portable Document Format) is the default choice for most scanning projects because it is the most versatile and widely compatible format available:

Opens on every computer, tablet and smartphone without special software
Supports multi-page files — an entire 50-page document is one file
Supports OCR text layers for full-text search
Smaller file sizes than TIFF (typically 3-5 times smaller)
Easy to email, share and upload
PDF/A variant is ISO-standardised for long-term preservation

For most business scanning — office documents, financial records, correspondence, contracts — PDF (preferably PDF/A) is the right choice. It gives you searchability, compatibility and manageable file sizes.

TIFF for Archival Quality

TIFF (Tagged Image File Format) is the traditional archival format, favoured by libraries, museums and organisations with long-term preservation requirements:

Lossless compression (TIFF-G4) — no image quality is lost, ever
No compression artefacts — every pixel is preserved exactly as scanned
Widely supported across all platforms and decades of software
Multi-page TIFF files are possible (though less convenient than multi-page PDF)
The master format from which all other formats can be derived

The trade-offs: TIFF files are 3-10 times larger than equivalent PDFs, they do not natively support searchable text layers, and they are less convenient for sharing and viewing.

Direct Comparison

File size: PDF wins — significantly smaller, especially with JPEG or JPEG2000 compression
Image quality: TIFF wins — lossless means no quality loss at any point
Searchability: PDF wins — native OCR text layer support
Compatibility: PDF wins for viewing (opens anywhere); TIFF wins for image processing
Long-term preservation: Both good — PDF/A is ISO-standardised; TIFF is the established archival standard
Multi-page support: PDF wins — more convenient and widely supported multi-page handling

Using Both

For organisations with both daily access needs and long-term preservation requirements, the dual-format approach works well: scan to TIFF-G4 as the master preservation copy, then generate PDF/A with OCR for everyday use. This gives you the best of both worlds — archival-quality originals and practical searchable files.

The cost of producing both formats is minimal — most scanning software can output both simultaneously. The main additional cost is storage space for the larger TIFF files.
