# PDF Compressor vs Compress PDF

The clearest difference is ads: Compress PDF at none against PDF Compressor's shown. Compress PDF also leads on update cadence (fortnightly vs every 6 weeks) and review sentiment (100% vs 89%). PDF Compressor's advantage is rating (5.0 vs 4.7) and iOS requirement (14.0 vs 17.6). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. PDF Compressor sells 3 in-app purchases, starting at $2.99 per 7 days and Compress PDF sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Compressor holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 5 and 14 respectively. Written reviews complicate that: 89% of PDF Compressor's written reviews are positive against 100% of Compress PDF's, so the app with the better star average is not the one people write more warmly about.

PDF Compressor ships an update every 6 weeks, Compress PDF fortnightly. The most recent releases landed on June 3, 2026 and September 15, 2026 respectively.
