# aDumAVar vs PDF Compressor

The clearest difference is rating: PDF Compressor at 4.6 against aDumAVar's 2.0. PDF Compressor also leads on ratings volume (871 vs 3). aDumAVar's advantage is review sentiment (67% vs 26%) and ads (none vs shown). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PDF Compressor holds the better App Store score, 4.6 against 2.0. That said, the two scores are not equally well evidenced: PDF Compressor has 871 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of aDumAVar's written reviews are positive against 26% of PDF Compressor's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. Both last shipped on November 7, 2026.
