TIFF to PDF
Turn a TIFF or TIF file, such as a scanned document or a fax, into a PDF that anyone can open. Every page of the TIFF becomes a page of the PDF. It all happens on your own device.
How to use it
- Choose every page or the first page only.
- Choose your TIFF files, or drag them onto the box.
- Download each PDF, or all of them together as a ZIP file.
How the pages are sized
Each TIFF page becomes one PDF page. Its paper size comes from the resolution stored in the TIFF, so a page scanned at A4 comes out at A4. If the TIFF has no resolution stored, 96 dots per inch is assumed. Each TIFF you choose becomes its own PDF; to join them into one, use Merge PDF afterwards.
How it works
Most browsers cannot open TIFF files, so this page uses ImageMagick, the well-known picture program, running inside your browser. It is about 5 MB and is downloaded the first time you convert a TIFF. Black-and-white pages, such as faxes, are stored sharply without loss; other pages are stored as high-quality JPG pictures, which keeps the PDF a sensible size.
The text in a scanned page is a picture, not text you can select. To make it searchable, use Make PDF searchable on the result.
Files that may not convert, or may differ
A small number of TIFF files use rare kinds of compression, called LZMA and WebP, that cannot be opened here; the page tells you if yours is one of them. Specialist scientific TIFFs, such as those storing signed 16-bit values or Lab colour, may come out with different brightness or colour from the program that made them.
Questions
Are my files uploaded?
No. The work happens inside your web browser, on your own device. Before your file is opened, this page locks itself: from then on your browser refuses to let it fetch, upload or send anything at all. You can check: once the page has loaded, switch off your internet connection and it will still work. How the lock works.
