TIFF to PDF

TIFF to PDF converts TIFF image files — including multi-page TIFFs from document scanners, medical imaging equipment, and archival workflows — into a single PDF document. Each frame in a multi-page TIFF becomes one page in the output PDF. TIFF is a lossless format commonly used in professional scanning, healthcare (DICOM-adjacent workflows), legal documentation, and long-term archiving. This tool handles the full range of TIFF variants: LZW-compressed, uncompressed, greyscale, RGB, RGBA, and 1-bit (fax) TIFFs.

TIFF to PDF is designed for archivists, medical teams, solicitors, and anyone working with scanner-produced TIFF files. It runs entirely in your browser — your files are never uploaded to any server.

Step 1: Add your file. Click the upload area above or drag and drop your tiff images directly onto it. Step 2: Adjust settings if needed. Use the settings panel to configure options such as output quality, page range, or file naming. Step 3: Run the tool. Click the action button. For simple tasks this takes a few seconds; for larger files or complex operations like OCR it may take up to a minute. Step 4: Download your result. The output file downloads automatically. No email, no sign-up, no waiting room.

One important note: if you are processing confidential documents — financial statements, legal contracts, medical records, or identification — none of this data passes through any external server. The entire operation runs inside your browser, and the file is cleared from memory when you close the tab.

A single-page A4 TIFF at 300 DPI (approximately 25 MB uncompressed) converts to a PDF page in 3–8 seconds depending on device speed. A 10-page multi-page TIFF at 200 DPI converts in 15–30 seconds. Each frame is rasterised individually before being embedded into the output PDF. Output PDF file size is typically 60–80% of the total input TIFF size when the source images are photographic. Line-art and text-heavy TIFFs compress more aggressively in the PDF container.

If you are preparing files for a specific portal, check the upload limit before processing. Compress PDF is available immediately after this tool if you need to reduce file size for submission.

Multi-page TIFFs are fully supported — each IFD (image frame) inside the TIFF becomes a separate page in the output PDF. Confirm the page count in the downloaded PDF matches the number of frames in the source TIFF. 1-bit black-and-white TIFFs (common in fax machines and older scanners) are supported and convert cleanly. The output will be greyscale, not colour. Very high-resolution TIFFs (600 DPI or above, over 100 MB) may be slow to process on mobile devices. For large archival TIFFs, a desktop browser is strongly recommended. TIFF files with CMYK colour space are converted to RGB during the rasterisation step. Colour values may shift slightly — if colour accuracy is critical, compare the output against the original before distributing.

When you use a typical online PDF tool, your document is uploaded to a company's server, processed there, and returned as a download. During that process, the company technically has access to your file. For sensitive files — payslips, ID documents, client contracts — that is a real privacy consideration.

PDF Genius Pro takes a different approach. TIFF to PDF runs entirely in your browser using standard web technology. Your file is read by your browser's JavaScript engine, processed locally, and saved to your downloads folder. At no point does the file travel to a server. This is why the tool continues working even if your internet connection drops mid-process — it does not need the internet to do its job once the page has loaded.

Take a moment to review the output before sending it on. The most important checks for tiff to pdf are: Confirm the page count in the PDF matches the number of frames in the source TIFF. Check that all pages are the correct orientation — scanner-produced TIFFs sometimes include rotated frames. Verify image clarity at 100% zoom — if text is blurry, the source TIFF may have been scanned at too low a resolution. Check that the file size is within any portal or email attachment limit before submitting.

If the result does not look right, you can re-run the tool with different settings at no cost. Adjusting quality, page range, or file order are quick fixes. The tool is designed to support iteration.

TIFF to PDF works on mobile browsers including Safari on iPhone and iPad, and Chrome on Android. The upload area supports tap-to-browse on mobile devices, and drag-and-drop works on tablets. Processing is handled by your device's own processor, so performance depends on your device's speed and available memory.

For very large files (over 30 MB), a desktop browser on a computer with more RAM will give faster and more reliable results. For typical document tasks, mobile processing works well.
