Why convert TIFF to PDF?
TIFF is the format scanners, fax services and archives use, and it’s excellent at storing pages without losing detail. Outside those systems, though, TIFF is awkward: most browsers won’t display it, many email and phone apps can’t preview it, and upload forms for applications or claims usually ask for a PDF.
Converting the TIFF to PDF keeps every page at full resolution, while giving you a file that opens on any computer or phone and can be printed, signed or attached anywhere.
How the pages are stored
Each page is decoded in your browser and placed on its own PDF page at full resolution:
| TIFF page | Stored in the PDF as | Why |
|---|---|---|
| Black and white (1-bit) | Lossless | Sharp text, small files |
| Palette (indexed color) | Lossless | Keeps flat colors exact |
| Grayscale or color | JPEG at the quality you choose | Much smaller for photos and color scans |
With Fit to image, each PDF page gets the scan’s real size when the TIFF records its resolution, so a 300 DPI Letter scan becomes an 8.5 × 11 inch page. Files without a usable resolution get a standard page size in the same shape. A4 and US Letter place each page centered with half-inch margins, turning sideways for landscape pages.
Page orientation stored in the file is applied, CMYK pages are converted to RGB, and color profiles and metadata aren’t copied. Need images instead? Convert TIFF to JPG for small files or TIFF to PNG for lossless ones.
