# PDF Converter vs Sign PDF Documents

The clearest difference is monetization model: Sign PDF Documents at freemium against PDF Converter's subscription. Sign PDF Documents also leads on rating (4.9 vs 4.4). PDF Converter's advantage is ratings volume (6K vs 55) and iOS requirement (15.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PDF Converter sells 13 in-app purchases, starting at $4.99 per 7 days and Sign PDF Documents sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Sign PDF Documents holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: PDF Converter has 6K ratings behind it against 55, so its average is the more settled of the two.

PDF Converter ships an update fortnightly, Sign PDF Documents every 3 weeks. The most recent releases landed on September 24, 2026 and September 10, 2026 respectively.
