Combine PDFs is a tool that lets you carry out basic operations on your PDF documents.
For starters, you can use Combine PDFs to merge together several PDF documents into one, reorder pages, and get rid of pages you consider unnecessary.
You can also rotate pages to the left, or right, as well as establish the document’s geometric properties: Art Box, Bleed Box, Crop Box, Media Box y Trim Box.
Plus, if you drag an image onto the program’s interface, it’ll appear as just one more page within the same PDF document. The last step consists in editing the metadata that is included in the lower part of Combine PDFs: title, author and created by.
