PDF management: passwords, properties, merging, conversion and modification, all together

Sometimes, after you write some tricks and articles on a topic and after reporting various programs and tools, one to do one thing, one to do another, then you happen to find yourself in front of a software, which does everything together and which it does it faster and easier.
PDF files are the protected standard widely used to share documents online so that, once written, they cannot be reproducible or editable; this is because most people use that awkward tool called Adobe Acrobat Reader that doesn't allow you to do anything and that is just a viewer.
So let's do a quick summary to understand how to manage pdf files and what you can do:

• We have in another article the best alternatives to replace Adobe Acrobat Reader.
• To create a pdf file you don't need to buy expensive software, you can do it easily and quickly on any computer.
• We have the tools to combine two pdf files into one and, vice versa, to separate the pages of a single file.
• We know how to edit non-editable pdf files, transforming them into text files.
• We also tried to unlock pdfs with passwords even if with difficulty and with tight constraints.

Now, we finally have a very small and easy-to-use program that allows you to manage this type of document so that you no longer have difficulty setting passwords, removing them, changing properties and depersonalizing the file from how its author had created it.

1) Quick PDF Tools Free version is a very small program that must be installed on the computer and integrated with the contextual menus that appear by pressing the right mouse button. This means that when you want to use it, you don't have to open the program separately but just right-click on a pdf file and see the appearance of this management menu.
Available functions include:

• Password management to protect a document or to unprotect it. You can add the password you need to open it and you can remove it (it is not a crack, it is a serious program and to remove a password you need to know the one used at the time of protection).
• By selecting two or more pdf files, you can combine them by pressing the "Merge" button which then allows you to choose the order of the pages that make up the new file.
• Modify the document properties, ie its internal information that cannot be edited with a simple Reader. The properties include the name of the document, the author and the table of contents showing the content.
• Remove all bookmarks, i.e. links inside the document.
• Modification of the display properties with the choice of the graphic layout that can be imposed in full screen, without any menu whatever the reader used and which page of the document to open at the beginning which must not necessarily be the first.
• For an unprotected document, you can choose to automatically move all the content and words of the pdf into a text file so that you can edit it, bring it back to a well-formatted and recreated Word file.
• Alternatively, you can choose to transform the pages of the pdf file into static images that are smaller in size and are no longer editable.
• By right clicking on any image, QuickPDF Tools allows you to convert the image into a pdf file .
• See the preview of the first page of the pdf document.

However, the feature that pleasantly surprised me, beyond all these management utilities, is the speed of command execution that allows everyone to use it without any difficulty and without dirtying the computer.
2) A similar all-in-one PDF management program is Advanced PDF Utilities Free, free, which allows you to:

• See the preview of the PDF file.
• Modification of metadata such as title, author, subject, etc;
• Converting PDF to images, images to PDF, PDF to TXT and from PDF to Word;
• Merge PDF or split (split) a document into several PDFs;
• Scan of paper documents in PDF format and OCR function to extract text.
• Removing protection passwords.

3) A third program for managing PDF files is PDF Shaper
The program is a collection of tools to perform various operations on PDF files. You can therefore:

• Extract text
• Extract images
• Convert PDF to images - Turn a PDF file into individual JPEG images.
• Convert images to PDF
• Convert PDF to RTF
• Extract pages from a PDF file and save them as separate files.
• Merge multiple PDF documents into one file.
• Encrypt or decrypt PDF files.

4) CleverPDF is a website that includes practically every tool to work PDF files: convert them to other formats, create PDF from documents, compress PDF, extract images from PDF, split and merge PDF files, unlock password-protected PDFs, edit PDF properties and much more, all free.
5) LightPDF is a web app that works without downloading anything, which includes all the most important PDF management tools including: Converting PDF to Word and PowerPoint documents or PNG and JPEG images, adding signature and logo, uninone PDF, division a document, password protection and locking.
6) PDFCandy is another site that contains many free tools that can be used online by the browser. You can then convert a PDF to many different formats, cut a PDF, merge multiple files into one PDF, reduce the size, password protect the PDF, rotate pages and delete pages from a document.
