Verdict

The call

The clearest difference is rating: UPDF at 4.6 against PDF Extractor's 3.0. UPDF also leads on update cadence (fortnightly vs every 23 months) and ratings volume (694 vs 2). PDF Extractor's advantage is review sentiment (100% vs 84%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. UPDF sells 13 in-app purchases, starting at $9.99 per month and PDF Extractor sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

UPDF holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: UPDF has 694 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 84% of UPDF's written reviews are positive against 100% of PDF Extractor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

UPDF ships an update fortnightly, PDF Extractor every 23 months. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
