Verdict

The call

The clearest difference is rating: The Document Converter at 4.7 against PDF Compressor's 4.3. The Document Converter also leads on ratings volume (5.9K vs 533). PDF Compressor's advantage is update cadence (every 5 weeks vs every 5 months) and review sentiment (46% vs 36%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

The Document Converter holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: The Document Converter has 5.9K ratings behind it against 533, so its average is the more settled of the two. Written reviews complicate that: 36% of The Document Converter's written reviews are positive against 46% of PDF Compressor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

The Document Converter ships an update every 5 months, PDF Compressor every 5 weeks. Both last shipped on October 16, 2026.
