Free PDF Merger

Thanks to their multi-platform support and portability, PDF files are among the most widespread text formats out there. One of their few downsides is the fact that they are not that easily modifiable, especially if you want to add content to a document and increase its page number without damaging the text formatting.

Free PDF Merger is a handy application that enables you to combine PDF files and maintain the original formatting, attachments and attributes. The documents can be added in batch mode using the dedicated button and you can move them around inside the list to organize their final merging order.

To help you distinguish between them, the program displays information about the path, file size and creation date alongside each document. Although there are no specific limits to how many PDFs you can add or merge at the same time, you have to keep in mind that the larger the file, the more time it takes to complete the process.

A nice feature that comes with Free PDF Merger is the built-in document viewer, which allows you to explore the files and even zoom in, switch pages, or print them on paper. You can also view and edit their properties, such as title, author and keywords, which can be permanently saved as the document's metadata information.

In case you want to restrict the access to the newly created file, you can add a password protection and require it every time someone tries to open the document. The password is fully encrypted and it can be 25 characters long at most. A digital signature can also be applied, complete with PFX password, certificate and contact information.

Thanks to the bundled PDF viewer and digital signature capabilities, Free PDF Merger is more than a simple document joiner. The intuitive interface and easy-to-use features make it a very good alternative when it comes to PDF-related file operations.
