Convert TIF/TIFF to PDF — What Actually Works
The technical truth
TIFF/TIF is a rich archival format (multi-page, many compression schemes) that modern browsers cannot decode — so no pure web tool can read it directly. The routes below are guaranteed:
Windows
- Open the TIF with the built-in Photos app.
- Print (Ctrl+P) and pick the Microsoft Print to PDF printer.
- Multi-page files: repeat per page, then merge the outputs.
macOS
Open in Preview, then File > Export as PDF — exports all pages at once.
Mobile
Gallery apps usually open TIFF; Share > Print > Save as PDF.
After converting
TIFF conversions are image-heavy — run the result through PDF compression (grayscale for scans) to shrink it hard, or extract its text if it is a scanned document.
