Verdict
The clearest difference is rating: PDF Compressor at 4.3 against PDF's 3.5. PDF Compressor also leads on ads (none vs shown) and update cadence (every 6 weeks vs every 5 months). PDF's advantage is review sentiment (33% vs 0%) and iOS requirement (15.0 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PDF sells 3 in-app purchases, starting at $4.99 per 7 days and PDF Compressor sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
PDF Compressor holds the better App Store score, 4.3 against 3.5. That said, the two scores are not equally well evidenced: PDF Compressor has 83 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 33% 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.
PDF ships an update every 5 months, PDF Compressor every 6 weeks. Both last shipped on October 24, 2026.
