Verdict
The clearest difference is review sentiment: TIFF Viewer at 100% against PDF Compressor's 26%. TIFF Viewer also leads on update cadence (every 10 days vs every 2 months). PDF Compressor's advantage is rating (4.6 vs 4.0) and in-app purchases (none vs 1). On price, ads and device support there is nothing between them.

Both are free to download. TIFF Viewer sells 1 one-off in-app purchase. PDF Compressor asks for nothing beyond the download.
PDF Compressor holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: PDF Compressor has 813 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 26% of PDF Compressor's written reviews are positive against 100% of TIFF Viewer's, so the app with the better star average is not the one people write more warmly about.
PDF Compressor ships an update every 2 months, TIFF Viewer every 10 days. The most recent releases landed on October 13, 2026 and September 25, 2026 respectively.
