# PDF Master vs PDF转换器

PDF Master and PDF转换器 are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. PDF Master sells 13 in-app purchases, starting at $2.99 per 7 days and PDF转换器 sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 26, 2026 and October 9, 2026 respectively.
