PDF to TIFF Converter

TIFF is still the format of choice for document archives, fax software, print shops and many scanning workflows, because one .tif file can hold every page at a fixed resolution with lossless compression. This tool renders each PDF page in your browser and writes a standard baseline TIFF — one multi-page file or one file per page — without sending the document anywhere.

How to use this tool

1. Drop one or more PDF files and, if needed, list the pages to convert.
2. Choose the resolution: 200 DPI for fax-style documents, 300 DPI for print or archiving.
3. Pick colour, 8-bit grayscale or 1-bit black and white.
4. Keep LZW compression unless a program asks for something else, then download the TIFF.

Formula

Pixels = page size in points ÷ 72 × DPI

PDF pages are measured in points (72 per inch). An A4 page (595 × 842 pt) at 300 DPI becomes 2480 × 3508 pixels. Black & white uses 1 bit per pixel with a brightness threshold; grayscale uses 0.299 R + 0.587 G + 0.114 B. LZW, Deflate and PackBits are all lossless, so the pixels are identical; only the file size differs.

Example

A 2-page A4 letter at 200 DPI in black and white gives one TIFF of 1654 × 2339 pixels per page. Each page is about 484,000 bytes uncompressed (207 bytes per row × 2339 rows); LZW stores the long white runs of a text page very compactly, so such a file usually ends up at a small fraction of that size.

Compatibility notes

LZW is understood by practically every TIFF reader. Deflate (ZIP) is smaller and supported by Photoshop, GIMP, libtiff-based tools and most modern viewers, but some older fax programs reject it. CCITT Group 4 fax compression and JPEG-in-TIFF are not offered. Chrome and Firefox cannot display TIFF images, so the result is shown as a download only; Safari shows a preview.
