# Image To PDF vs Compressor

The clearest difference is rating: Compressor at 5.0 against Image To PDF's 1.0. Compressor also leads on update cadence (every 5 months vs every 27 months) and ratings volume (6 vs 1). Image To PDF's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Image To PDF sells 3 in-app purchases, starting at $2.49 per 7 days and 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.

Compressor holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: Compressor has 6 ratings behind it against 1, so its average is the more settled of the two.

Image To PDF ships an update every 27 months, Compressor every 5 months. Both last shipped on November 3, 2026.
