Frequently Asked Questions

What DPI should I use for PDF to TIFF?
300 DPI for standard archival, court filings, and professional printing. 600 DPI for small-font documents, technical drawings, and OCR processing. 200 DPI for on-screen viewing only. Most institutional guidelines specify 300 DPI as the archival baseline.
Does PDF to TIFF produce a multi-page file?
Yes. Each PDF page becomes one page (IFD entry) in the output TIFF. A 50-page PDF produces a 50-page TIFF in a single file — the standard format for document archives and court e-filing systems.
Is the text still searchable in the TIFF?
No. PDF to TIFF rasterizes all content — text becomes pixels and is no longer selectable or searchable. Run OCR afterward (Tesseract, ABBYY, Adobe Acrobat) to add a searchable text layer.
What compression does Convertify use for PDF to TIFF?
CCITT Group 4 for black-and-white pages (extremely compact, fax-compatible) and LZW for color pages (lossless, 30–50% smaller than uncompressed). Compression type is selected automatically based on page content.
How large is the TIFF output?
At 300 DPI with LZW compression, a color A4 page is typically 1–3 MB. A B&W text page with CCITT Group 4 compression is 30–80 KB. Multi-page documents scale linearly — a 20-page color PDF produces a roughly 20–60 MB TIFF.
Does PDF to TIFF preserve hyperlinks or form fields?
No. TIFF is a raster image format — all interactive PDF features (hyperlinks, forms, bookmarks, annotations) are lost during rasterization. Keep the original PDF for interactive features.
Can I convert a password-protected PDF to TIFF?
Yes, if you know the password. Enter it when prompted. If you do not know the password, use a PDF unlock tool first.
Why does my TIFF look blurry?
Almost always a DPI issue. Many tools default to 72 DPI — only 595×842 pixels for an A4 page. Re-convert at 300 DPI for sharp text and graphics.

Rasterization: turning vector pages into pixels

A PDF page has no inherent resolution — it is a set of drawing instructions. The rasterizer executes every text glyph, vector path, transparency blend, and embedded image onto a pixel grid at the DPI you choose. At 300 DPI, an A4 page (8.27 × 11.69 inches) becomes a 2480 × 3508 pixel image. At 600 DPI, the same page is 4961 × 7016 pixels — four times the data.

The DPI decision is irreversible: once rasterized, you cannot zoom in beyond the sampled resolution without visible pixelation. For text documents and line art, 300 DPI is the minimum for legible print output. For archival scans and OCR processing, 600 DPI captures fine serifs and thin strokes that 300 DPI may blur. Going above 600 DPI rarely adds visible detail for text-and-vector PDFs — it only multiplies file size.

Multi-page TIFF: one file, many pages

PDF files commonly contain dozens or hundreds of pages. TIFF handles this natively through chained IFD (Image File Directory) entries — each page is a separate image within one .tiff file. A 50-page contract PDF becomes a 50-page TIFF where each page is independently addressable.

This makes TIFF the standard format for scanned document archives, court e-filing systems (PACER/CM-ECF in US federal courts), fax transmissions, and enterprise document management systems (DMS). Many DMS platforms — FileNet, Documentum, Laserfiche — treat multi-page TIFF as their canonical storage format because it combines image fidelity with sequential page access.

Compression: CCITT Group 4 for text, LZW for color

TIFF supports specialized compression schemes optimized for different content types. For black-and-white document pages (contracts, legal filings, faxes), CCITT Group 4 compression is the standard. It is a fax-era algorithm designed specifically for 1-bit bilevel images and achieves extraordinary compression ratios — a B&W A4 page at 300 DPI can compress from 1 MB raw to 30–80 KB. This is why fax machines and court filing systems use CCITT TIFF.

For color pages — photographs, charts, marketing materials — LZW lossless compression is the right choice. LZW typically reduces color TIFF page size by 30–50% compared to uncompressed storage while preserving every pixel exactly.

Convertify detects page content type and applies CCITT Group 4 for B&W pages and LZW for color pages automatically.

DPI selection guide

Choosing the right DPI depends on the downstream use. 200 DPI is the minimum for readable text documents — suitable for on-screen viewing and basic archiving. 300 DPI is the standard for professional printing, court filings, and general-purpose archival. Most institutional guidelines (including US National Archives and state court e-filing systems) specify 300 DPI as the baseline for document preservation.

600 DPI is recommended for small-font documents, technical drawings with fine lines, and images destined for OCR processing where character recognition accuracy depends on glyph edge clarity. Archival best practices recommend using TIFF with lossless compression at 300–600 DPI — higher resolutions for documents with fine detail, lower for standard business correspondence.

For photographic PDF pages (brochures, catalogs), 300 DPI matches the minimum standard for photo-lab quality output.

What you lose in PDF to TIFF conversion

Converting PDF to TIFF is a one-way transformation that discards several PDF capabilities. Selectable text becomes pixels — you can no longer copy, search, or highlight text in the TIFF. Hyperlinks, form fields, bookmarks, and annotations are gone. Vector graphics become rasterized at the chosen DPI — zooming beyond that resolution reveals pixelation where the PDF would remain sharp.

If you need searchable text after conversion, run OCR (Tesseract, ABBYY FineReader, Adobe Acrobat) on the resulting TIFF to add a text layer. For preserving text selectability, keep the original PDF alongside the TIFF archive.

For rasterized output in web-friendly formats, try PDF to JPG or PDF to PNG.

How Convertify converts PDF to TIFF

Convertify uses libvips with a PDFium rendering backend — the same engine Google Chrome uses to display PDFs. PDFium's Skia-based rasterizer produces high-quality anti-aliased text and vector graphics. Each page is rendered at the selected DPI into an RGBA tile buffer, then encoded to TIFF with the appropriate compression (CCITT Group 4 for bilevel, LZW for color).

For CMYK PDFs (common in prepress), Convertify applies an ICC profile transform from CMYK to sRGB before TIFF encoding, since TIFF output targets screen display rather than press output. Multi-page PDFs produce multi-page TIFFs with each page as a separate IFD. EXIF metadata is not applicable (PDFs are not photographs), but the TIFF receives standard dimensional and compression tags for compatibility with document management systems.
