# Synthy vs PDF Editor・PDF File Converter

The clearest difference is review sentiment: Synthy at 81% against PDF Editor・PDF File Converter's 18%. PDF Editor・PDF File Converter's advantage is rating (4.7 vs 4.2). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Synthy sells 7 in-app purchases, starting at $4.99 per 7 days and PDF Editor・PDF File Converter sells 10 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Editor・PDF File Converter holds the better App Store score, 4.7 against 4.2. Both are backed by a comparable volume of ratings — 385 and 154 respectively. Written reviews complicate that: 81% of Synthy's written reviews are positive against 18% of PDF Editor・PDF File Converter's, so the app with the better star average is not the one people write more warmly about.

Synthy ships an update monthly, PDF Editor・PDF File Converter every 3 weeks. Both last shipped on November 3, 2026.
