Converting a PDF to a multipage TIFF is one of the most common document workflow tasks in archiving, legal, medical, and printing industries — yet most people struggle to find a reliable free tool that doesn't require installing software or uploading confidential files to a third-party server. This free PDF to multipage TIFF converter solves that problem entirely: it runs 100% in your browser, processes your file locally, and produces a single TIFF file where every PDF page becomes a separate image frame.
Whether you're working on a Mac or Windows machine, using Chrome, Firefox, or Safari, this online converter handles the entire process client-side using PDF.js — the same engine that powers Firefox's built-in PDF viewer. You choose the DPI, choose color or grayscale, and download a clean multipage TIFF in seconds. No software subscription, no account, no watermark.
🎯 Key insight: A multipage TIFF is not just a folder of images — it is a single binary file containing all page frames in sequence. This is the format required by fax gateways, document management systems (DMS), hospital PACS imaging systems, and legal archiving software like iManage and NetDocuments.
TIFF (Tagged Image File Format) is one of the oldest and most trusted formats in professional imaging. Unlike JPEG, which loses quality every time you re-save it, TIFF supports lossless compression — meaning your document images stay sharp and readable indefinitely. The multipage variant of TIFF is sometimes called a "multi-frame TIFF" or "multi-strip TIFF" and stores each document page as a separate IFD (Image File Directory) inside a single file.
This is critically important for organizations that need to store scanned documents in a single container file. Most enterprise document management systems, fax-over-IP services, and healthcare imaging platforms natively read and write multipage TIFF. Uploading a PDF to these systems often requires converting it to multipage TIFF first — which is exactly what this tool does.

DPI (dots per inch) controls how many pixels are used to represent each inch of the original PDF page. Higher DPI means sharper text and clearer images, but also a larger file. Here is a practical guide to choosing the right DPI for your use case:
⚠️ Important: If your source PDF was originally a low-resolution scan (e.g., a faxed document scanned at 100 DPI), increasing the output DPI will not recover lost detail — it will only make the file larger. The maximum useful output DPI is limited by the resolution of the source content. For best results, use original high-resolution PDFs or vector PDFs.
This tool makes the PDF to multipage TIFF conversion process as simple as possible. Here is a detailed walkthrough of every step to help you get the best possible output:
Before uploading your PDF, select the output DPI. The default is 200 DPI, which is correct for the vast majority of document workflows. If you are creating files for a fax gateway or document archive, keep it at 200. If you need high-quality output for legal or medical purposes, switch to 300. If you are creating preview thumbnails or email attachments, 150 DPI is sufficient and will produce a much smaller file.
Color mode preserves all original colors from the PDF. This is the right choice for documents with color graphics, branded letterheads, charts, or highlighted text. Grayscale mode converts everything to black and white and produces TIFF files that are typically 60–70% smaller than their color equivalents. Grayscale is the correct choice for fax transmissions, black-and-white text documents, and archiving workflows where storage space matters.
Click the upload area or drag and drop your PDF file into it. The tool accepts any PDF file that your browser can render using PDF.js. This includes text PDFs, scanned PDFs, and PDFs with embedded images. Password-protected PDFs are not supported — you will need to remove the password protection first using another tool before converting.
Once your PDF is loaded, click the "Convert to Multipage TIFF" button. The tool will render each page of your PDF on an HTML canvas at the selected DPI, then encode all the canvas frames into a single multipage TIFF binary file using standard TIFF encoding. For a 10-page PDF at 200 DPI, this typically takes a few seconds. For very large PDFs (50+ pages at 300 DPI), it may take 30–60 seconds depending on your device.
After conversion, a page preview grid will appear showing thumbnails of each page. Click "Download Multipage TIFF" to save the file. The filename will match your original PDF filename with a .tiff extension. Open it in any TIFF viewer — Windows Photo Viewer, Apple Preview, Adobe Acrobat, or your document management system — and you will see all pages in sequence.
💡 Pro tip: On a Mac, you can open your downloaded multipage TIFF directly in Preview. Use the sidebar (View → Thumbnails) to see all pages at once. On Windows, open the TIFF in Windows Photo Viewer or IrfanView — both support multipage TIFF natively.
The quality of your output TIFF depends primarily on the quality of your source PDF. Here are the most important factors to consider:
Multipage TIFF conversion is a specialized need, but it comes up regularly in many professional contexts. Here are the most common use cases and why a browser-based tool is the ideal solution:
Courts and legal document management systems often require filings in multipage TIFF format, particularly for older e-filing systems and legacy case management platforms. Lawyers, paralegals, and legal assistants frequently need to convert client-provided PDFs into TIFF before submitting. A browser-based tool is ideal because it avoids installing proprietary software on firm computers and processes documents locally without sending them to external servers — a key requirement when handling confidential legal materials.
Hospital and clinic document workflows frequently involve multipage TIFF. PACS (Picture Archiving and Communication Systems) and EMR (Electronic Medical Records) platforms historically used TIFF for document imaging. When converting patient records, consent forms, or referral documents from PDF to TIFF for import into these systems, privacy is critical — this tool processes everything locally in the browser, so patient data never touches an external server.
National archives, municipal records offices, and corporate document management teams often store documents in multipage TIFF as their master archival format. TIFF with LZW or CCITT Group 4 compression is the preferred format for long-term digital preservation because it is lossless, well-documented, and not subject to proprietary licensing. Converting PDFs to multipage TIFF for archival is a routine task in these environments.
Fax machines and modern fax-over-IP services transmit documents in TIFF format internally. When you send a document by fax, it is typically converted to TIFF at the fax gateway. Some enterprise fax platforms allow users to pre-convert PDFs to multipage TIFF before upload, giving more control over the output resolution and format. This tool makes it easy to produce a fax-ready TIFF from any PDF.
Insurance claims systems, mortgage processing platforms, and financial document workflows often require TIFF submissions. Policy documents, claims forms, and contracts received as PDFs need to be converted to TIFF before being ingested into these platforms. A zero-upload browser tool is particularly valuable here because financial documents often contain personally identifiable information (PII) that should not be processed by external services.
Commercial print shops and prepress workflows sometimes require TIFF files rather than PDFs for specific RIP (Raster Image Processor) workflows. Converting a PDF to a high-resolution 300 DPI TIFF ensures that the image is fully rasterized before it enters the print pipeline, eliminating potential rendering issues with complex PDF content. This is particularly useful for large-format printing where consistent rendering is critical.
✅ Privacy guarantee: This tool processes your PDF entirely in your browser. Your file is never sent to ImageConverter24's servers or any third-party service. It is rendered locally using PDF.js and encoded locally using JavaScript. This makes it safe to use with confidential documents in any industry.
If you work in document management, archiving, or IT, understanding the technical details of TIFF format helps you make better decisions about your document workflows. Here is what you need to know about how this tool creates TIFF files and how to work with them.
A TIFF file starts with an 8-byte header containing a byte-order marker (little-endian or big-endian), a TIFF magic number (42), and a pointer to the first Image File Directory (IFD). Each IFD contains metadata about one image — its width, height, bits per sample, compression type, and a pointer to the actual pixel data. Multipage TIFF files chain multiple IFDs together: the last field of each IFD is a pointer to the next IFD, forming a linked list of pages. This tool generates standard little-endian TIFF files compatible with all major TIFF readers.
This tool uses PackBits compression for TIFF output, which provides moderate lossless compression and maximum compatibility across all TIFF readers. For even smaller files, LZW or CCITT Group 4 (for black-and-white documents) would produce smaller outputs, but at the cost of reduced compatibility with some older systems. If you need TIFF files with specific compression types for a particular platform, check whether that platform has a recommended conversion tool or supports repacking TIFF files post-conversion.
Color mode output uses 8 bits per channel × 3 channels (RGB) = 24-bit color, which is standard for color document imaging. Grayscale mode uses 8 bits per channel × 1 channel = 8-bit grayscale. Some archiving workflows, particularly those using CCITT Group 4 compression for fax, require 1-bit bilevel (black-and-white only) images. If you need strict 1-bit TIFF output, use the Grayscale mode in this tool and then apply threshold conversion in a tool like GIMP or ImageMagick.
As a rough guide, a single letter-size (8.5×11 inch) page at 200 DPI color will produce an uncompressed image of approximately 2,240 × 1,760 pixels = about 11.8 megapixels × 3 bytes = ~35MB per page uncompressed. With PackBits compression on a typical document page, this typically compresses to 2–8MB per page depending on content complexity. At 300 DPI, expect roughly 2.25× more pixels (and file size) than at 200 DPI. Grayscale reduces file size by approximately 3× compared to color at the same DPI.
