The PDF format is great for displaying any device, regardless of the operating system. The flexibility of the format is also reflected in allowing the user to do many things to increase visibility and efficiency. With the right tool, you can merge multiple .pdf documents into one, or a single document to divide into more. Another tool can help you extract text and images, thirdly cut, rotate or remove content, and a fourth tool can help you encrypt, decrypt, or sign documents. A fifth tool could help change the metadata of documents, and with the six you can convert .pdf documents to the .jpeg format, and vice versa.
AlterPDF is a program that can do all of this. The best of everything? It's completely free.
The latest, second version allows you to work with several documents from once, which you get on time, and do not bother by switching from one to another individual file.
