Frequently Asked Questions
- What DPI does Convertify use for PDF to TIFF?
- Convertify renders at 300 DPI, the common standard for printing, document filing, and general archival. As a rule of thumb, 200 DPI is the minimum for readable text, 300 DPI suits most documents and OCR, and 400 to 600 DPI is for fine detail or archival masters. Selectable DPI is planned.
- Does PDF to TIFF produce one multi-page file?
- Not a single multi-page .tiff today. Convertify converts each PDF page to its own TIFF and, for a multi-page document, delivers them together in a ZIP archive. A single-page PDF returns one TIFF directly. If you need all pages inside one multi-page TIFF, combine the individual files afterward in a tool that writes multi-page TIFF.
- 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?
- Convertify currently outputs lossless TIFF, so no detail is discarded. It does not yet let you pick a compression scheme such as CCITT Group 4 for black-and-white pages or LZW and ZIP for color; those options are planned. Lossless means quality is preserved, though files can be larger than compressed equivalents.
- How large is the TIFF output?
- Lossless TIFF files can be large, and size scales with resolution and page count: a full-color page at 300 DPI holds millions of pixels, so multi-page color documents can run to tens of megabytes. If size matters, a lower resolution or a more compact format like PDF may suit better. Exact size depends on the page content.
- 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?
- Not yet. Convertify does not currently handle password-protected or encrypted PDFs. Remove the password in your PDF viewer first (for example by opening it with the password and re-saving without one), then upload the unprotected file. Direct support for protected PDFs is planned.
- 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.
- What is the difference between .tif and .tiff?
- There is none. Both extensions refer to the same Tagged Image File Format. The three-letter .tif comes from older systems that limited extensions to three characters; the file contents are identical and modern software opens either.
- Is there a maximum TIFF file size?
- Yes. Classic TIFF uses 32-bit offsets and is therefore limited to 4 GB, per the LibTIFF documentation. Larger images use a 64-bit variant called BigTIFF. Ordinary document conversions stay well under the limit, but very high-resolution, many-page color jobs can grow large, so consider fewer pages per file if size is a concern.
- Can I convert a geospatial PDF to GeoTIFF here?
- This converter produces standard TIFF images, which is ideal for documents and maps you want as pictures. It does not write a true GeoTIFF that carries spatial reference tags for GIS analysis; preserving coordinate metadata is a separate, GIS-specific operation that needs a dedicated geoprocessing tool.
- Why does my converted TIFF have a black or transparent background?
- This happens when a PDF page contains transparency that is rasterized without being flattened onto a solid background. A correct conversion flattens the page against white so the TIFF matches the original document. If you see an unexpected background, it usually points to unflattened transparency in the source PDF.
- Can I use this for medical or PACS images?
- You can convert PDF reports, forms, and scanned records to TIFF for systems that accept it. Note that primary diagnostic imaging uses DICOM rather than plain TIFF, so use TIFF for document-style content rather than as a replacement for DICOM studies.
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 rendering resolution. Convertify renders at 300 DPI, the standard for printing, document filing, and general archival. At 300 DPI an A4 page (8.27 by 11.69 inches) becomes a 2480 by 3508 pixel image; at 600 DPI the same page would be 4961 by 7016 pixels, four times the data.
This step is one way: once a page is rasterized at a given resolution, the text and vectors are pixels. There is no resolution to step back up to, so the rendering DPI sets the ceiling on sharpness.
Multi-page PDFs and multi-page TIFF
The TIFF format itself can hold many pages in one file through chained IFD (Image File Directory) entries, which is why scanned archives and fax systems often use a single multi-page TIFF. It is worth knowing how the format works if a downstream system expects that layout.
Convertify handles multi-page PDFs in a straightforward way today: each PDF page is converted to its own TIFF, and for a multi-page document those files are delivered together in a single ZIP archive. A single-page PDF returns one TIFF directly. If your workflow specifically needs all pages bundled inside one multi-page .tiff, you would combine the individual TIFFs afterward in a tool that writes multi-page TIFF.
TIFF compression options, and what Convertify outputs
TIFF supports several compression schemes, and knowing them helps you prepare files for a target system. CCITT Group 4 is a bilevel (1-bit) scheme designed for black-and-white text and fax pages, and it produces very small files for clean text. LZW and ZIP (Deflate) are lossless schemes for color and grayscale that preserve every pixel while reducing size; for high-bit-depth images ZIP is usually preferred over LZW. JPEG-in-TIFF is lossy and suited only to photographic content, while uncompressed TIFF is the largest but most universally readable.
Convertify currently outputs lossless TIFF, so no image detail is discarded. It does not yet expose a choice of compression scheme or a bilevel (Group 4) mode; those are described here for context so you can plan around your target system's requirements.
DPI and resolution: what to know
Resolution drives both clarity and file size. 200 DPI is roughly the minimum for readable text and on-screen use; 300 DPI is the common standard for professional printing, document filing, and general archival; 400 to 600 DPI is reserved for fine detail, small fonts, technical drawings, or archival master images, at the cost of much larger files. Many institutional guidelines, including US National Archives (FADGI) and various court e-filing systems, treat 300 DPI as the baseline for document preservation.
Convertify renders at 300 DPI, which suits the large majority of document and filing use cases. Higher or selectable resolution is planned.
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 first normalizes the PDF with Poppler (pdftocairo), which repairs signed or lightly corrupted files, then renders each page with libvips at 300 DPI. Each rendered page is written as a lossless TIFF. A single-page PDF returns one TIFF; a multi-page PDF returns one TIFF per page, packaged in a ZIP.
The whole pipeline runs server-side in Rust, and uploaded files are removed automatically after processing. For CMYK source PDFs, the page is rendered to standard RGB, so if you need true CMYK separations with a specific ICC profile, plan to apply that in a prepress editor.
Why convert PDF to TIFF? Common use cases
Most people convert PDF to TIFF because a specific system or standard expects a faithful page image rather than a searchable document. Legal e-filing and e-discovery workflows often require TIFF page images that are easy to stamp and redact. Archival programs treat lossless TIFF as the preservation master, following guidance such as the US National Archives FADGI standards. OCR pipelines frequently ingest high-resolution TIFF for text recognition, fax and document-management systems expect TIFF, and print and prepress workflows use it as a RIP-friendly raster master. In short, choose TIFF when exact image fidelity or compatibility with a particular system matters more than text search or small size.
TIFF vs PDF and PDF/A: which to keep
TIFF and PDF solve different problems. TIFF is a raster image: it captures the page pixel by pixel, is lossless, and is ideal as an archival or production image master, but it has no searchable text and files are large. PDF, and especially the ISO-standardized PDF/A, keeps selectable text and stays compact and universally viewable, which makes it the better everyday and long-term document format. A common best practice is to keep both: a TIFF as the imaged master where a system requires it, and a searchable PDF or PDF/A for access. Convert to TIFF when a target workflow specifically needs a page image rather than a document.
How to open and view a TIFF file
Most web browsers do not display TIFF, which surprises many first-time users, so a downloaded TIFF may not preview in the browser. On Windows, open TIFFs with Photos or Windows Photo Viewer, which also pages through multi-page TIFFs. On macOS, Preview opens and exports them. Cross-platform tools like IrfanView, XnView, and GIMP read TIFF as well, and most professional imaging and document-management software opens it directly. If a file refuses to open, it is usually a viewer that lacks support for a particular TIFF variant rather than a damaged file.
