There is a new mini bundle, this time published by Paddle. The so called Mini PDF Bundle contains 2 apps for only 4$. As there is no hint how long the bundle will be available, you’d better be quick.
Here comes the short summary of both apps:
PDF Squeezer
reduces the size of PDF files.
PDF Protector
encrypts and decrypts PDF files with a 40-bit or 128-bit encryption.
