How to Convert TIFF to PDF

Before you start

A TIFF file can be a single image or a multi-page document, so the conversion result depends on how the file was saved. Check the page count, page size, pixel dimensions, aspect ratio, and whether the file uses transparency or compression before picking a conversion method. If the TIFF is already on your computer, a local image viewer, document tool, or print-to-PDF option can usually create a PDF without uploading the file. An online converter is an alternative, but it transfers the file to a third-party service; avoid it for sensitive documents unless you have verified how the service handles files.

Step-by-step instructions

The steps below cover common desktop and mobile workflows. Menu names can differ slightly between versions or operating systems, so treat the exact labels as a guide rather than a fixed path.

Convert with a local image or document tool

• Open the TIFF in an application that can read this file format, such as a document viewer, image editor, or scanning utility.
• Select the export, save as, or print function.
• Choose PDF as the output format.
• If available, set the page size to match the original TIFF or choose an option such as original size or actual size to keep the aspect ratio.
• If the TIFF contains multiple pages, check that the dialog includes all pages or select the option to export every page into one PDF.
• Save the PDF to a folder where you can find it.
• If the application does not list PDF as an export format, use its print dialog and choose a PDF printer or save as PDF option instead.

Convert on a mobile device

On a phone or tablet, open the TIFF in an app that supports viewing or editing images. Use the share menu or file menu to look for a make PDF, convert to PDF, print, or save as PDF option. If the device has a system print dialog with PDF output, that can also work. Some mobile apps may convert only the visible page, so check how many pages the resulting PDF contains.

Keep the original file

Do not replace the original TIFF with the PDF until you have confirmed the result. Keep the TIFF as the editable or archival copy, especially if it contains layers, transparency, or high-resolution scan data that may not translate perfectly into the PDF.

Check the output

• Open the PDF and scroll through every page to confirm that no pages are missing or reordered.
• Compare a sample page with the original TIFF at the same on-screen size; small differences in sharpness may be normal after conversion.
• Check the page count and page size in the PDF viewer or file properties.
• If the TIFF used transparency, inspect areas that should be transparent; some converters flatten transparency to a solid color.
• Check the PDF file size. A heavily compressed output may look softer or blocky, while an uncompressed PDF can be much larger than expected.
• Zoom into fine text or thin lines to see whether the conversion preserved enough detail for the intended use.

Common problems and next steps

A common issue is a TIFF that opens as a completely black or blank PDF. This can happen when the TIFF uses a compression method, color mode, or bit depth that the converter does not fully support. If the converted PDF is blank, the TIFF appears damaged, or the file uses an unusual compression setting, open the TIFF first in an image tool and save a copy as an uncompressed TIFF or a standard color mode, then convert the copy.

If the aspect ratio looks wrong, the converter may have stretched the image to fill a standard page. Change the page setup to use the original pixel dimensions or original size, and disable page scaling or fit-to-page when possible. If the output is too large, check the PDF export settings for image quality or compression options and reduce them only if the lower detail is acceptable.

If your application cannot open the TIFF, the file may be a raw camera image, a different image format with the wrong extension, or a multi-page TIFF that needs another viewer. Confirm the file type and try a local image converter that supports the actual file format. If the PDF needs to be searchable or editable, converting TIFF to PDF only creates an image-based PDF; optical character recognition is a separate step.
