Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
