FreePDF

FreePDF is a software application capable of changing the page orientation of multiple PDF documents at the same time. It also has a feature for merging files into a single item.

The tool doesn't have elaborate settings, making it suitable for all sorts of users, even those inexperienced with PDF processing software.

After the brief setup that needs minimal user intervention, you're welcomed by a standard panel that shows large buttons and all options provided by the program, representing the whole interface.

Since batch processing is supported, you can add as many PDFs as you want to the task list by resorting to the integrated file browser. If supported, the drag-and-drop function didn't work in our case.

The utility reveals the full file path of each entry and facilitates three buttons for rotating them to the left or right by 90 degrees, or by 180 degrees. The modification is applied only after confirming it, though. Before proceeding, you should know that the original files are processed, so the app doesn't create new ones. You might be interested in building backups before allowing the operation.

As for the merging operation, FreePDF automatically combines the pages of all PDFs in the list and puts them in a single document in the same location as the source items, following the order in the queue. Two buttons are provided for rearranging the entries by moving them up and down if you want to make adjustments in this regard.

When it comes to settings, you can modify the default saving directory for new files and instruct the tool to rotate only a specified page range instead of all sheets. Rotation and joining tasks were carried out fast in our tests. Taking everything into account, FreePDF proves to be a speedy tool for running bulk operations to rotate PDF pages and merge files into one.
