Convert scanned documents, faxes and photos saved as TIFF into a PDF that opens anywhere. Multi-page TIFFs keep all their pages, the page size follows the scan's resolution, and you can combine many files into one PDF or convert a whole batch at once. Nothing is uploaded.

Each page of a multi-page TIFF gets its own card. Drag to change the order (on touch screens use the ⠿ handle); focus a page and press Alt + ←/→ to move it, R to rotate, Delete to remove.

How to use the TIFF to PDF Converter
Add your TIFF files by dropping them on the box or clicking to choose them. Multi-page files expand into one card per page.
Check the pages: drag to reorder, rotate sideways scans or remove blank pages.
Choose the page size. Same as image uses the DPI stored in the TIFF, so a 300 dpi A4 scan becomes an exact A4 page.
Pick the compression: Lossless for documents and line art, JPEG for colour photos.
Press Convert to PDF. Choose One PDF per file to convert a batch into separate PDFs in a ZIP.
TIFF and PDF for scanned documents
TIFF (Tagged Image File Format) has been the standard for scanners, fax servers and archives since the late 1980s. One TIFF can hold many pages, and it supports lossless compression schemes, from LZW and Deflate for colour images to CCITT Group 4 for black-and-white documents. The downside is that browsers, phones and many document systems cannot display TIFFs, while every device opens a PDF.
This converter reads each page of the TIFF, and places it on a PDF page. With Same as image, the page size comes from the resolution tag: page width in inches = pixel width ÷ DPI. That keeps scans at their real paper size, so they print at 100% without scaling.
Common scan sizes
Paper

300 dpi
600 dpi
A4 (210 × 297 mm)
1654 × 2339 px
2480 × 3508 px

US Letter (8.5 × 11 in)
1700 × 2200 px

US Legal (8.5 × 14 in)

2550 × 4200 px
5100 × 8400 px
Choosing the compression
Lossless keeps every pixel. Pages that are purely black and white are stored at 1 bit per pixel, grayscale pages at 8 bits and colour pages as RGB, all Flate-compressed. Best for text, forms, drawings and archives.
JPEG high / balanced / small is best for colour photos and magazine-style scans, where it can make the file several times smaller. Avoid it for black-and-white text, where JPEG adds grey fringes around letters.

Frequently asked questions
How do I convert a multi-page TIFF to PDF?
Add the TIFF file above. Every page appears as its own card, in the original order. Press Convert to PDF and you get one PDF with the same number of pages.
Can I combine several TIFF files into one PDF?
Yes. Add all the files, arrange the pages and keep Output set to One PDF. To convert each TIFF into its own PDF instead, choose One PDF per file and the PDFs are downloaded together as a ZIP.
Will the PDF have the same page size as my scan?
With Same as image, the page size is calculated from the pixel size and the resolution stored in the TIFF. For example 2480 × 3508 pixels at 300 dpi gives an A4 page (210 × 297 mm). If the TIFF has no resolution, 96 dpi is assumed; choose A4 or Letter to fit it to a standard page instead.
Is the conversion lossless?
With Lossless compression the exact pixels are stored using Flate (zip) compression, and pure black-and-white pages are stored as 1-bit images, which is how most scanned-document PDFs are made. The JPEG options re-compress the image to make colour pages smaller.
Which TIFF types are supported?
Uncompressed, LZW, Deflate (zip), PackBits and JPEG-compressed TIFFs in 1, 2, 4, 8 or 16 bits per channel, grayscale, RGB, palette and CMYK are decoded directly. Fax TIFFs with CCITT Group 3 or 4 compression and other rarer variants are decoded with the UTIF library, which is downloaded only when needed.
Why is my PDF larger than the TIFF?
Fax-style TIFFs use CCITT compression, which is extremely efficient for black-and-white pages. The lossless Flate compression used in the PDF is usually close, but can be somewhat larger. For colour scans, a JPEG option makes the PDF much smaller.
Are my files uploaded?
No. The TIFF is decoded and the PDF is built entirely in your browser, so confidential scans never leave your device.
Are all the tools on FreeToolCabin tested for quality and accuracy?
Yes! Every tool on our site undergoes automated Q/A testing in real browser environments to ensure high precision, correct output, and zero errors. If you happen to spot a bug or have a suggestion, please contact us at [email protected] and our team will review it right away.
