Verdict
The clearest difference is monetization model: PDF Expert at free with in-app purchases against Image Converter's subscription. PDF Expert also leads on ratings volume (216K vs 9K) and chart position (#73 vs unranked). Image Converter's advantage is review sentiment (68% vs 46%) and iOS requirement (13.1 vs 16.0). On price, rating, ads and in-app purchases there is nothing between them.

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

Written reviews are what separate them: 46% of PDF Expert's written reviews are positive against 68% of Image Converter's.
