Why convert TIFF to PDF?
TIFF (Tagged Image File Format) is the standard archival format for scanned documents, medical imaging, and professional photography. Scanners, document management systems, and reprographics workflows produce TIFF files routinely. The problem is distribution: TIFF is not a universal viewing format — most email clients display TIFFs as attachments rather than inline, web browsers do not render them, and most users cannot open them without dedicated software.
PDF is the distribution standard for scanned documents. Converting TIFF → PDF means your scanned contracts, invoices, land surveys, medical reports, or archival documents can be opened by anyone on any device using the free PDF viewer already installed. The visual quality of the source scan is fully preserved in the PDF.
Multi-page TIFF is a specific use case worth calling out: scanners often produce a single .tiff file containing tens or hundreds of pages from a document feed. File Converter Pro converts multi-page TIFFs to multi-page PDFs, preserving the page sequence exactly. Batch single-page TIFFs can be merged into one PDF or kept as individual documents.
The conversion runs entirely offline — essential for legal, medical, and government documents that must not leave the local network.
How to convert TIFF to PDF on Windows
- Install File Converter Pro. Download File Converter Pro from the Microsoft Store. The free trial supports TIFF to PDF conversion at full resolution.
- Add TIFF files to the queue. Drag TIFF files into the app. Single-page TIFFs, multi-page TIFFs, and folders of scanned pages are all supported. The app detects multi-page TIFFs automatically.
- Choose single PDF or merged PDF. Select "One PDF per TIFF" for individual documents, or "Merge all to one PDF" to combine a batch of scanned pages into a single file.
- Convert offline. Click Convert. Output PDFs are generated locally — no upload. A 100-page scanned TIFF document converts to PDF in under a minute on modern hardware.
Batch conversion for big folders
Document digitisation projects often produce folders of thousands of TIFF scans that all need to become PDFs. File Converter Pro handles these production batches without per-file limits.
- Process entire folders of TIFF scans in one run — no job size limit.
- Multi-page TIFFs are correctly expanded into multi-page PDFs.
- Folder structure can be mirrored in the output directory for organised archive maintenance.
- The queue continues uninterrupted even if individual corrupt TIFFs are found — they are logged and skipped.
Quality settings that actually matter
TIFF is usually uncompressed or losslessly compressed (LZW). When embedding in PDF you can choose how the image is stored:
- Lossless (TIFF/LZW in PDF): preserves every pixel exactly. Larger PDF files but zero quality loss. Use for archival, legal, and medical records where pixel fidelity is required.
- JPEG in PDF (quality 90): good for scanned text and photographs where a slight compression is acceptable. Significantly smaller PDF.
- JPEG in PDF (quality 75): compact PDFs for email distribution. Slight visible softness on very fine text at high zoom.
- DPI settings: preserve source DPI (typically 300 or 600 for document scans) or downsample for smaller files.
Common issues and fixes
- Multi-page TIFF only exports one page. Ensure the multi-page TIFF option is enabled in the output settings. The app detects multi-page TIFFs automatically in most cases.
- PDF pages are black-and-white when source was colour. The TIFF was probably saved as 1-bit bilevel (fax/G4) by the scanner. This is the source data, not a conversion error. Use a higher-quality scan setting on your scanner for colour output.
- Very large PDF output. Lossless embedding of 300 DPI scans produces large files. Switch to JPEG quality 85 in the output settings to significantly reduce PDF size while keeping text readable.
- Page order wrong in merged PDF. Drag to reorder files in the queue before converting. Default sort is alphabetical.

FAQ
Can File Converter Pro convert multi-page TIFF to PDF?
Yes. Multi-page TIFF files — where a single .tiff stores dozens of document pages — are converted to equally multi-page PDFs with the correct page sequence preserved.
Will TIFF to PDF conversion reduce image quality?
Only if you choose JPEG embedding in the PDF output settings. With lossless embedding (the default for archival use), every pixel is preserved exactly. Choose lossless for legal, medical, or archival PDFs.
Can I merge many individual TIFF scans into one PDF?
Yes. Add all your TIFF files to the queue, set the merge mode to "Combine all into one PDF," arrange page order in the queue, and convert. The result is one multi-page PDF.
Does TIFF to PDF conversion work offline?
Yes. Everything runs locally on your Windows 10 or 11 PC. Your scanned documents — legal contracts, medical records, financial reports — never leave your machine.
