ReceptionRating · Positive reviews · Number of ratings

PDF Merge holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: PDF Compressor has 56 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 18% of PDF Compressor's written reviews are positive against 0% of PDF Merge'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 3 weeks, PDF Merge weekly. The most recent releases landed on August 29, 2026 and September 20, 2026 respectively.
