Verdict

The call

The clearest difference is ads: PDF Expert at none against PDF Converter's shown. PDF Expert also leads on ratings volume (216K vs 531) and update cadence (fortnightly vs every 2 months). PDF Converter's advantage is review sentiment (77% vs 45%) and monetization model (ad-supported vs free with in-app purchases). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. PDF Expert sells 10 in-app purchases, starting at $9.99 per month and PDF Converter sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.7 for PDF Expert against 4.8 for PDF Converter.

Written reviews are what separate them: 45% of PDF Expert's written reviews are positive against 77% of PDF Converter's.

UpkeepUpdate frequency

PDF Expert ships an update fortnightly, PDF Converter every 2 months. The most recent releases landed on October 17, 2026 and October 15, 2026 respectively.
