What is a PDF file?


Portable file format (PDF) is a file format produced by Adobe Inc. It contains mainly text and graphics, and is used for viewing eBooks, forms and scanned documents. To view and edit PDF files, PDF softwares are used. PDF viewers are usually free, while softwares that include editors and other features, are generally subscription based. Adobe Acrobat Reader is one example of a popular free software that allows the user to view, create or edit the document, which includes things like annotate, highlight, and
add notes to already created PDF files.

PDF files are especially useful for documents such as magazine articles, product brochures, or flyers in which you want to preserve the original graphic appearance online. A PDF file contains one or more page images, each of which you can zoom in on or out from. You can page forward and backward


The most defining aspect of PDF (Portable Document Format) is clearly its portability. Regardless of the device or operating system you are using, the original layout, including fonts and pictures will look the same to you, on screen and printed on paper. It also makes no difference which software was used to write the file, you can rely on the result to look the same - everywhere


Another aspect which makes PDF one of the most popular formats is its security. PDF files can be secured with a password and it can be defined whether a user can open, print or edit a file. This helps you to keep control over your data and to protect sensitive information.


With a PDF converter tool you have many more possibilities than simply saving files as PDF. It lets you preselect where your files are going to be auto-saved and which email address they will be sent to. Furthermore, you can use tokens to predefine certain values like today's date, your user name or a counter that increases each time you print a document. This can be very helpful when you print a lot of documents of the same sort, like for example invoices.
