What is PDF Merge (Beta)?
PDF Merge was created with the ability to create PDF documents and merge them in specific order as a combined PDF document. There are many PDF tools out there but this one was built out of specific requirements and ease of use.
The project is no longer developed. Last version, Beta Release v1 (the initial release), released in February 2013, can be still downloaded from Codeplex.
