Verdict

The call

The clearest difference is review sentiment: PDF at 100% against PDF Compressor's 0%. PDF also leads on update cadence (every 4 months vs every 43 months) and iOS requirement (13.0 vs 15.0). PDF Compressor's advantage is in-app purchases (none vs 3) and rating (4.6 vs 4.3). 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 4.3. That said, the two scores are not equally well evidenced: PDF Compressor has 19 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of PDF's written reviews are positive against 0% of PDF Compressor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PDF ships an update every 4 months, PDF Compressor every 43 months. The most recent releases landed on September 7, 2026 and September 11, 2026 respectively.
