What happens when you convert TIFF to PDF
- The TIFF is placed on a PDF page the same size as the image, stored losslessly.
- A small TIFF decoder is fetched when you press Convert. For multi-page TIFF files, the first page is converted.
How to convert TIFF to PDF online
- Press "Choose TIFF files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
- Adjust the settings if you need to. The output is lossless, so there is no quality setting to worry about.
- Press "Convert to PDF". Images convert in a second or two each.
- Save each PDF with its download button. Close the tab and every trace of the files is gone from memory.
Why convert TIFF to PDF?
TIFF files usually come from print production, scanning, archiving and medical imaging. People convert them to PDF because a PDF looks the same on every device and is what forms, portals and printers ask for.
In short, TIFF is good at what it was made for, and PDF is the more practical choice when the file has to open, upload or print somewhere else. Safari shows TIFF; Chrome, Edge and Firefox download it instead of displaying it, while PDF opens in every browser's built-in viewer.

Best settings for TIFF to PDF
Each image becomes one page sized to the image at 96 pixels per inch, so a 1200 pixel wide image makes a page 12.5 inches wide. PDF viewers and printers scale pages to fit, so the page size rarely matters on screen.
The TIFF is stored with lossless compression inside the PDF, so it is exactly as sharp as the original. Transparent areas are placed on a white page.

About TIFF and PDF files
What is a TIFF file?
TIFF is the format printers and archives trust because it can store uncompressed or losslessly compressed pixels, CMYK colour and several pages in one file. It is also why a single scan can run to 100 MB.
What is a PDF file?
A PDF fixes the layout of every page so it looks the same on any device. Converting a PDF to an image renders each page to pixels; converting an image to PDF wraps it as a page.
TIFF to PDF not working? Common problems
- Colours look slightly different. Browsers convert images to the standard sRGB colour space when they decode them, so wide-gamut and CMYK images can shift a little.
- A phone photo comes out upright even though it looked sideways elsewhere. That is correct: the rotation stored in the photo is applied during conversion, so the PDF is always the right way up.
- Transparent areas turned white. PDF cannot store transparency; convert to PNG or WebP instead if you need it.
Convert TIFF to PDF from the command line
If you work in a terminal, ImageMagick converts TIFF to PDF in one line:
magick input.tiff output.pdfTo convert every TIFF in a folder at once, use magick mogrify -format pdf *.tiff. The converter on this page does the same job without installing anything.
TIFF to PDF converter FAQ
Will I lose quality converting TIFF to PDF?
No further quality is lost, because PDF is written losslessly. Detail the TIFF compression already removed does not come back.
Why is the PDF a different size from the TIFF?
The PDF is usually larger, because it stores every pixel without compression losses, while the TIFF was compressed lossily.
Are my TIFF files uploaded anywhere?
No. The conversion runs inside this browser tab using your browser's own image decoder, so your files stay on your device. You can disconnect from the internet after the page has loaded and it still works.
Can I convert several TIFF files to PDF at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a PDF file?
PDF opens in every browser's built-in viewer. PDF is common for documents, forms, invoices and print-ready files.
Is this TIFF to PDF converter free?
Yes. There is no sign-up, no watermark and no limit on how many files you convert. The site is paid for by advertising, and because conversions run on your device there is no server cost per file.
Can I convert TIFF to PDF on my phone?
Yes. The converter works in Safari on iPhone and iPad and in Chrome on Android. Converted files are saved to the Downloads folder.
