# 一键清图 vs PDF Image Extract

The clearest difference is rating: PDF Image Extract at 5.0 against 一键清图's 4.0. 一键清图's advantage is update cadence (every 10 days vs every 3 months) and review sentiment (81% vs 67%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 一键清图 sells 1 one-off in-app purchase and PDF Image Extract sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PDF Image Extract holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 3 and 1 respectively. Written reviews complicate that: 81% of 一键清图's written reviews are positive against 67% of PDF Image Extract's, so the app with the better star average is not the one people write more warmly about.

一键清图 ships an update every 10 days, PDF Image Extract every 3 months. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
