# 企查查 vs PDF转换器

The clearest difference is rating: PDF转换器 at 5.0 against 企查查's 2.1. PDF转换器 also leads on update cadence (fortnightly vs every 6 weeks). 企查查's advantage is ratings volume (52 vs 2). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. 企查查 sells 9 in-app purchases, starting at $9.99 per month and PDF转换器 sells 12 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF转换器 holds the better App Store score, 5.0 against 2.1. That said, the two scores are not equally well evidenced: 企查查 has 52 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 61% of 企查查's written reviews are positive against 54% of PDF转换器's, so the app with the better star average is not the one people write more warmly about.

企查查 ships an update every 6 weeks, PDF转换器 fortnightly. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
