Convert PDF to TIFF Online Free
TIFF is an uncompressed image format designed for maximum quality. Files are significantly larger than JPG or PNG — a single A4 page at 300 DPI color is approximately 25 MB.
✅ For smaller files: use 150 DPI or Grayscale mode
⚠️ 600 DPI produces very large files (~100 MB per color page). Use it only when high-resolution archival output is required. Convert in small page ranges to avoid browser memory issues.

✨ Why Convert PDF to TIFF?
TIFF (Tagged Image File Format) is the gold standard for archival, printing, and document imaging workflows. Unlike PDF, which requires a PDF reader, TIFF files can be opened by virtually any image viewer, editing application, or document management system. Converting PDF to TIFF is essential for faxing, legal document filing, medical imaging (DICOM compatibility), print production, and long-term archival where uncompressed, pixel-perfect output is required. TIFF supports high-resolution multi-page images with embedded DPI metadata, making it ideal for regulated industries and professional print workflows.
Legal & Court Filing
Many courts and legal systems require document submissions in TIFF format for e-filing, as TIFF ensures unalterable, page-level image integrity.
Print Production
Convert PDF pages to high-resolution 300 DPI TIFF for professional printing, prepress workflows, and offset lithography.
Fax & Document Systems
TIFF is the standard format for internet fax and enterprise document management systems that don't accept PDF input.
Medical & Scientific
Convert technical PDF reports to TIFF for integration with medical imaging (PACS/DICOM) and scientific imaging systems.
Long-Term Archival
TIFF is the recommended format for long-term digital preservation by libraries, archives, and government agencies worldwide.
Secure Conversion
Convert confidential documents to TIFF without uploading to any server. All processing happens locally in your browser.

PDF to TIFF Converter – Complete Guide
PDF (Portable Document Format) is the universal format for sharing formatted documents across devices and platforms. TIFF (Tagged Image File Format) is the standard format for high-fidelity image archival, professional printing, legal filing, and document imaging systems. This guide explains when and why you need to convert PDF to TIFF, how the browser-based conversion process works, what settings to choose, and best practices for getting the best results.
What Is TIFF and Why Convert PDF to It?
TIFF was created by Aldus Corporation (now Adobe) in 1986 and has become the de facto standard for uncompressed, high-quality image storage in professional workflows. Unlike PDF, which is a structured document format with text, vectors, and embedded fonts, TIFF stores a pure pixel-based raster image of each page — making it unalterable at the text level and universally viewable by any image application.
Key reasons to convert PDF to TIFF include:
- Legal E-Filing: Many courts (including US federal courts via CM/ECF) require document submissions in TIFF format because it provides page-level image integrity — text cannot be edited after conversion.
- Professional Printing: Prepress workflows often require TIFF input at 300+ DPI for offset lithography, large-format printing, and color-separated output.
- Fax Compatibility: Internet fax services and legacy fax systems use TIFF (specifically TIFF-F / RFC 2301) as their native format.
- Document Management Systems: Enterprise DMS, ECM, and records management platforms often ingest documents as TIFF rather than PDF.
- Medical & Scientific Imaging: PACS, DICOM gateways, and scientific imaging pipelines often require TIFF input with specific DPI and bit-depth metadata.
- Long-Term Archival: Libraries, archives, and government agencies (including the US National Archives) recommend uncompressed TIFF for digital preservation because it requires no proprietary decoder.
- Image Integrity: Converting to TIFF "freezes" the page as pixels, preventing unauthorized text modification — important for contracts, certificates, and official records.
How PDF to TIFF Conversion Works (Browser-Based)
Converting PDF to TIFF in a browser involves two key steps: PDF page rendering and TIFF image encoding. Here's the technical process:
- File Reading: The PDF file is read from your local filesystem using the File API as an ArrayBuffer.
- PDF Parsing: Mozilla's PDF.js library parses the PDF structure — page tree, fonts, images, vectors, and content streams.
- Page Rendering: Each selected page is rendered onto an HTML5
<canvas>element at the chosen DPI (scale = DPI / 72, since PDF's native coordinate system is 72 DPI). - Pixel Extraction: The canvas pixel data (RGBA) is extracted using
getImageData(). - Color Conversion: If grayscale mode is selected, each pixel is converted using the luminance formula: Gray = 0.299×R + 0.587×G + 0.114×B.
- TIFF Encoding: A custom JavaScript TIFF encoder writes the pixel data into a standards-compliant TIFF file with proper IFD entries, byte alignment, and embedded DPI metadata.
- Blob Generation: The encoded TIFF binary data is wrapped in a Blob and converted into a downloadable Object URL.
- ZIP Packaging: For multi-page PDFs, each page's TIFF Blob is added to a JSZip archive for single-download convenience.
Note: This tool produces uncompressed TIFF files for maximum compatibility and quality. Uncompressed TIFF is universally readable and does not introduce any compression artifacts, making it suitable for legal, archival, and print workflows where lossless integrity is required.
Important: Because no browser can natively decode or display TIFF images in an <img> tag, the visual thumbnails shown in this tool are PNG renderings of each page — used purely for preview. The actual downloadable file for each page is a genuine, standards-compliant TIFF binary.

Security and Privacy Considerations
When converting legal documents, medical records, or confidential business files, privacy matters:
- Zero Network Transfer: Your PDF file is read directly from your device into browser memory. It's never transmitted over the network.
- No Server Storage: All PDF parsing, page rendering, and TIFF encoding happens in JavaScript in your browser.
- No Third-Party Access: Your document content is never sent to any analytics service or external API.
- Session Isolation: All file data is held in browser memory only during your active session. Closing the tab clears everything.
- Safe for Confidential Documents: Convert court filings, medical records, and proprietary documents without risk of exposure.
Troubleshooting Common Issues
Solution: Ensure the file is a valid PDF (not a renamed image or corrupted file). Password-protected PDFs are not supported by browser-based parsing — remove protection first.
Explanation: Uncompressed TIFF is inherently large — this is by design for quality integrity. Solution: Use 150 DPI instead of 300, or switch to Grayscale mode for text documents to reduce file size by approximately 66%.
Explanation: PDF.js renders PDFs using browser-available fonts. If the PDF uses embedded fonts not available in the browser, PDF.js substitutes similar alternatives. Solution: For pixel-perfect rendering, use Adobe Acrobat or Ghostscript.
Explanation: High-DPI rendering of many pages uses significant memory. Solution: Convert pages in smaller ranges (e.g., "1-10", then "11-20") instead of all at once, or use a lower DPI setting.
Solution: Use the format "1,3,5-8" (commas between individual pages, hyphens for ranges). Do not include spaces between numbers and hyphens. "All" converts every page.
Best Practices for Successful Conversion
- Choose DPI Based on Purpose: 72 DPI for screen-only, 150 DPI for standard documents, 300 DPI for print or legal filing.
- Use Grayscale for Text Documents: Text-heavy documents look identical in grayscale and produce files roughly one-third the size of color.
- Convert Page Ranges: For large PDFs, convert specific page ranges to avoid browser memory issues.
- Verify Critical Documents: Compare a few converted TIFF pages against the original PDF to confirm rendering quality meets your requirements.
- Keep Original PDFs: Retain original PDF files since TIFF output is raster — you lose the ability to select/search text.
- Check Court Requirements: If filing legally, verify the court's specific DPI and color mode requirements before converting.

Frequently Asked Technical Questions
Question 1: Is the TIFF output compressed or uncompressed?
Answer: This tool produces uncompressed TIFF (Compression tag = 1). Uncompressed TIFF is universally compatible and lossless, making it suitable for legal, archival, and print workflows. Compressed TIFF (LZW, PackBits, or JPEG-in-TIFF) is not currently supported.
Question 2: Can this tool handle password-protected PDFs?
Answer: No. PDF.js cannot decrypt password-protected PDFs in the browser without the password being entered. Remove password protection using your PDF editor before uploading.
Question 3: Does the TIFF output support multi-page TIFF?
Answer: No. Each page is output as a separate single-page TIFF file. Multi-page TIFF (where all pages are in one .tiff file) is not currently supported. For convenience, all pages are packaged into a ZIP file for single-download access.
Question 4: Why does the rendering differ slightly from Adobe Acrobat?
Answer: PDF.js is an independent PDF renderer and may handle complex fonts, transparency blending modes, or ICC color profiles differently than Adobe's native engine. For most documents, the output is visually identical. For pixel-critical work, verify against Adobe Acrobat output.
Question 5: What is the maximum PDF size this tool can handle?
Answer: There's no artificial limit, but browser memory is the practical constraint. A 100-page PDF at 300 DPI color requires several GB of memory during processing. For large documents, convert in smaller page ranges (10-20 pages at a time).
Frequently Asked Questions (FAQs)
Upload your PDF file, select DPI and color mode, choose which pages to convert, then click "Convert to TIFF" to generate and download your TIFF images instantly.
Yes. You can select up to 300 DPI for print-quality output. The TIFF format is uncompressed, so no quality is lost during encoding — every pixel from the rendered PDF page is preserved exactly.
No. All conversion happens entirely in your browser using JavaScript. Your PDF file is never uploaded to any server, making this tool completely private and secure.
Use 72 DPI for screen viewing, 150 DPI for standard documents, 200 DPI for good quality output, and 300 DPI for print-quality or legal filing requirements.
Yes. Enter a page range like "1,3,5-8" in the Pages field to convert only those pages, or leave it as "All" to convert every page.
TIFF files use uncompressed data for maximum quality and compatibility. A single A4 page at 300 DPI color is approximately 25 MB. Use grayscale or lower DPI for smaller files.
Color TIFF stores 3 channels (RGB) per pixel. Grayscale stores 1 channel per pixel, producing files roughly one-third the size. Text documents look identical in both modes.
No. Conversion happens entirely in your browser using PDF.js and a custom TIFF encoder. No software installation is required.
Yes, but with practical limits. High-DPI conversion of large PDFs may be slow or memory-intensive on mobile devices. Use 150 DPI or lower for best mobile performance.
This tool produces standards-compliant uncompressed TIFF at your chosen DPI. Verify your specific court's requirements (most require 300 DPI) and compare a sample output against your court's test viewer before bulk filing.
