Most of the time, PDF is the right output format. There is a small list of situations where it is not, and TIFF is the answer. TIFF (Tagged Image File Format) is a raster image format that predates PDF by years and refuses to die for very good reasons: it is lossless, it can compress with industry-standard algorithms, it supports multi-page documents, and it is the default in faxing, archival imaging, document scanning, and certain regulated industries. This guide walks through converting PDF to TIFF cleanly.
When TIFF beats PDF
Counterintuitive in a PDF-dominated world, but real:
- Faxing. Yes, fax still exists, especially in healthcare and legal. Fax machines and online fax services almost always expect TIFF.
- Archival imaging. Many enterprise document management systems store documents as multi-page TIFFs with metadata. A TIFF is "just" the image bytes; long-term preservation is well-understood.
- OCR pipelines. Some commercial OCR engines (older ABBYY versions, mainframe OCR systems) accept TIFF inputs only.
- Court and government submissions. Certain jurisdictions and agencies still require TIFF for document submission. The PDF in your hand may need to become TIFF on the way to the filing clerk.
- Color-managed pre-press for very specific workflows, particularly in newspaper production, where TIFF/IT lives on.
For everyday document workflows, stay with PDF. Convert to TIFF only when downstream tools demand it.
How TIFF and PDF differ
PDF describes a page model, paths, text, transparency, fonts, objects. TIFF describes a raster grid, pixels. Converting PDF to TIFF means rasterizing: turning every page into a bitmap at a specific resolution.
Once converted, the file is just pixels. Searchable text is gone (unless you add a separate OCR'd PDF alongside). Hyperlinks are gone. Bookmarks are gone. What remains is a fixed visual record of what each page looked like.
This is precisely the appeal for archival: there are fewer ways for the file to mean different things on different systems. And it is precisely the downside for re-use: you cannot edit anything.
Resolution, bit depth, and compression
Three knobs determine the size and quality of the TIFF you produce:
Resolution (DPI):
- 200 DPI, fax standard. Tiny files, readable but rough text.
- 300 DPI, document scanning standard. Reasonable balance of size and quality for most office documents.
- 600 DPI, archival or pre-press. Large files but excellent reproduction.
- 1200 DPI or higher, rare, for special imaging or fine line art.
Bit depth:
- 1-bit (bilevel), pure black and white. Tiny files. Best for text-only documents.
- 8-bit grayscale, 256 shades of gray. Good for documents with photographs in grayscale.
- 24-bit color, full RGB. Best for color documents, largest files.
Compression:
- CCITT Group 4, bilevel compression, near-lossless and tiny. Standard for fax and document archive.
- LZW, lossless general-purpose. Good for color/grayscale where you want lossless.
- PackBits, older, lossless, less effective than LZW.
- JPEG (within TIFF), lossy color compression. Smaller files, useful for color documents where some loss is acceptable.
- ZIP / Deflate, lossless general-purpose, similar to LZW.
For a typical office document destined for archive, 300 DPI / bilevel / Group 4 is the standard combination. For color documents going to fax, you typically convert to grayscale first since fax is bilevel.
CLI tools that produce TIFF
The strongest tools are open-source CLIs:
- Ghostscript. The Swiss Army knife. See Ghostscript introduction. A typical command:
gs -dNOPAUSE -dBATCH -sDEVICE=tiffg4 -r300 \
-sOutputFile=output.tif input.pdf
Use tiffg4 for bilevel + Group 4 compression, tiffgray for grayscale, tiff24nc for 24-bit color with LZW, tiff32nc with -sCompression=zip for color with Deflate.
pdftocairo -tiff input.pdf output.tif(poppler-utils). Newer rendering engine; produces TIFFs that match modern PDF rendering quality. See poppler-utils introduction.- ImageMagick.
convert -density 300 input.pdf -compress group4 -monochrome output.tif. Uses Ghostscript under the hood by default. Slower but more flexible image post-processing. mutool draw -F tiff -r 300 -o output.tif input.pdf(MuPDF). Light and fast. See MuPDF introduction.
GUI tools
For one-off conversions:
- Adobe Acrobat Pro. File → Export To → Image → TIFF. Lets you set resolution and compression per page or per document.
- ABBYY FineReader. Document → Save as Image. Excellent quality, especially for documents that will be OCR'd downstream.
- Foxit PDF Editor. Export to image including TIFF.
- PDFelement / Nitro / Smallpdf. All offer PDF-to-image export including TIFF. See Acrobat vs Foxit and Nitro vs Acrobat.
Multi-page TIFF vs one TIFF per page
TIFF supports multiple pages in a single file ("multi-page TIFF" or "TIFF directory"). This is the standard for document archive and fax: one file, all pages, mirrors the structure of the PDF.
To produce a multi-page TIFF:
gs -dNOPAUSE -dBATCH -sDEVICE=tiffg4 -r300 \
-sOutputFile=output.tif input.pdf
Most tools default to multi-page TIFF for multi-page PDFs. To produce one TIFF per page, add %d to the output name:
gs -dNOPAUSE -dBATCH -sDEVICE=tiffg4 -r300 \
-sOutputFile=output-%d.tif input.pdf
Some downstream systems prefer one file per page, especially for indexing. Check before you convert.
Color, grayscale, or bilevel?
Pick based on the source content:
- Pure text documents, bilevel (
tiffg4). 1-bit black and white, smallest file, no quality loss for text. - Mixed text and grayscale images, grayscale (
tiffgray). 8-bit grayscale, lossless with LZW or ZIP. - Color documents, 24-bit color with LZW or Deflate (
tiff24nc -sCompression=lzw). - Fax-destined files, bilevel CCITT Group 4 at 200 DPI. Match what your fax service expects exactly.
Down-sampling color to bilevel before fax is essential, color faxes generally do not exist.
Preserving text searchability
A TIFF is just an image. There is no text layer.
If you need both the visual archive and searchable text, the standard pattern is:
- Convert the PDF to TIFF for archive
- Keep the original PDF (with its text layer) for search
- Tag both with the same identifier in your document management system
Some systems do this automatically: ingest the PDF, store both representations, and treat the TIFF as the canonical record while the PDF supports search.
Common gotchas
File size explosion. A small PDF can produce a huge TIFF when you rasterize at high resolution. A 500 KB PDF at 600 DPI bilevel might become 5 MB; at 600 DPI 24-bit color, 80 MB.
Wrong color space. Converting to RGB TIFF when the source is CMYK can shift colors. For pre-press, use a tool that supports CMYK TIFF directly.
Anti-aliasing on text. Bilevel TIFFs cannot anti-alias. Text renders crisp but can look slightly jagged compared to the original PDF. This is expected and correct.
Aspect ratio. Some converters output TIFFs at the wrong page size if the PDF media box has unusual dimensions. Check page dimensions after conversion.
Page rotation. Pages rotated in the PDF (e.g., a landscape page mixed into a portrait document) sometimes lose their rotation on TIFF output. Pre-rotate or fix in post-processing.
Round-tripping back to PDF
If you need to take a TIFF back to PDF, common when the only file you have is a multi-page archival TIFF, use:
img2pdf output.tif -o reconverted.pdf
img2pdf losslessly wraps TIFF pages as PDF pages, preserving the bilevel compression. The resulting PDF is searchable only after OCR.
Practical recipe
For a typical office document destined for archive:
- Start with the source PDF
- Run
gs -dNOPAUSE -dBATCH -sDEVICE=tiffg4 -r300 -sOutputFile=archive.tif source.pdf - Verify with a TIFF viewer that all pages are present and legible
- Store the TIFF in the archive
- Keep the source PDF for search
For a fax-bound document:
- Convert at 200 DPI bilevel:
pdftocairo -tiff -tiffcompression group4 -r 200 source.pdf output.tif - Confirm grayscale/color content was successfully downsampled
- Submit to fax service
Takeaway
TIFF is the format you reach for when an external system specifically asks for it, fax, archival imaging, government submission, certain OCR pipelines. It is rarely the right primary working format in 2026, but it remains essential in narrow workflows. Pick resolution, bit depth, and compression based on content and destination. Multi-page TIFFs preserve document structure as faithfully as a flat-image format can. Pair the TIFF archive with the original PDF for search. If you need to first extract specific pages, for example, only the signed pages of a long contract, you can isolate them in Docento.app and then convert just those pages to TIFF.
