# PDF Reader vs Tiny JPEG/PNG/HEIC Compressor

The clearest difference is rating: Tiny JPEG/PNG/HEIC Compressor at 5.0 against PDF Reader's 4.5. PDF Reader's advantage is ratings volume (3.5K vs 2) and iOS requirement (13.0 vs 15.1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PDF Reader sells 10 in-app purchases, starting at $2.99 per month and Tiny JPEG/PNG/HEIC Compressor sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
