# Simple PDF Convert vs PDF ProX

The clearest difference is in-app purchases: PDF ProX at none against Simple PDF Convert's 6. PDF ProX also leads on rating (4.2 vs 4.0) and ratings volume (33 vs 5). Simple PDF Convert's advantage is ads (none vs shown) and update cadence (every 3 days vs weekly). On price, monetization model and device support there is nothing between them.

Both are free to download. Simple PDF Convert sells 6 in-app purchases, starting at $4.99 per 7 days. PDF ProX asks for nothing beyond the download.

PDF ProX holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: PDF ProX has 33 ratings behind it against 5, so its average is the more settled of the two.

Simple PDF Convert ships an update every 3 days, PDF ProX weekly. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
