PDF stands for Portable Document Format and is a storage format for digital documents, its main advantage is to facilitate the exchange of digital documentation in a reliable manner, regardless of the software, hardware or operating system with which the original document was generated and/or the platform that receives it for reading.

Originally developed by Adobe® Systems as a globally compatible file format based on the PostScript format, it has become an international standard for document and information exchange. 
In 2008, Adobe handed over control of PDF development to the International Organization for Standardization (ISO), making PDF an “open standard”. The specification for the current version of PDF (2.0) is documented in ISO 32000-2.

If at any time you need to convert, scan and/or edit a PDF document, don’t forget that we can help you with :

What is the origin of PDF?

In 1991, Dr. John Warnock, co-founder of the American software company Adobe Systems, known worldwide for the image editing program Adobe Photoshop, launched “Project Camelot”.
Its goal was to allow any user to create documents from any application and send an electronic copy of the document anywhere to be viewed and printed anywhere in the world from any platform. 

In 1992, Project Camelot was renamed PDF as we know it today and in 2008, it was released as an open source standard.

Why is the PDF format so popular?

The popularity of PDF came mainly from the fact that it is the solution to the tons of paper accumulated in offices, schools, universities, among other places of study and work.

Being able to convert all those documents into a digital file that can be stored in a small USB memory stick or in a simple e-mail is one of the reasons that have made it so popular.
Although in its origins it only allowed the inclusion of texts and images, nowadays it also supports links, annotations, among many other functionalities.

Any operating system can open a document in PDF format, whether on a desktop computer, a laptop, a cell phone or a tablet. It doesn’t matter which operating system you use, Windows, Mac, Linux, Android or iOS; the document will remain unchanged.

Another great reason that makes this format so popular is the fact that when you generate any PDF file from other documents and/or images, it will remain unchanged, Adobe PDF files retain all the data from the original file, even if the text, graphics, images, etc. come from different sources.

This means that everything will look exactly the same, because the PDF file does not lose its formatting, unlike others, which modify the original structure of the document, showing a very different appearance, messing up the pages and even displaying incomprehensible characters.

In conclusion; PDF format is multiplatform, compatible with the main operating systems and unlike the others, it does not alter its original structure.
