PDFLeo - PDF Linearization, Encryption and Optimization

PDFLeo is a command line utility to transform existing PDF files - such as linearization, encryption, decryption, compression, size reduction, and metadata modification. It can also be used to display information of PDF documents, such as metadata, security attributes and required fonts.

A typical use of PDFLeo is to post-process PDF files created by a word processor or a PDF generator, such as Word 2007 or FOP. You can use this program to optimize (linearization or size reduction), encrypt, add metadata etc. In addition to modifying existing files, you can use the program to collect meta data of PDF documents, such as title, author and creation date.

Both 32-bit and 64-bit executables are included in the package.
