# 图片压缩 vs PassOff

The clearest difference is device support: 图片压缩 at 3 against PassOff's 1. 图片压缩 also leads on iOS requirement (13.0 vs 18.5). On price, ads and in-app purchases there is nothing between them.

Both are free to download. 图片压缩 sells 1 in-app purchase, starting at $4.49 per year and PassOff sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
