What are PDF files?

PDF files (Portable Document Format) are a file type used to save documents in a format that can be easily viewed on various devices and operating systems without changing the format of text, images or graphics. This file type was developed by Adobe in the early 1990s.

Some basic points about PDF files

1. Flexibility in supply: PDF files can be viewed on different devices and operating systems (such as Windows, macOS, and Linux) with the same format, ensuring that the document looks the same, regardless of the device used to view it.
2. Maintain formattingPDF files keep text, images, and graphics formatted exactly as they were created, regardless of the program used to create or view them.
3. Security: PDF files can be protected with passwords and encryption, providing a high level of security to protect the content from unauthorized modification or viewing.
4. Print compatibilityPDF files are widely used in printing and publishing because of their ability to retain the original quality and formatting of documents.
5. Advanced capabilitiesMany elements can be included in PDF files, such as hyperlinks, buttons, interactive forms, multimedia files (such as audio and video), and digital signatures.
6. Easy to sharePDF files can be easily emailed or shared online, and are often compact in size compared to other file types.

In short, PDF files are a powerful and flexible tool for saving and exchanging documents securely and reliably.
