Whether you have ever encountered the problem of saving documents to PDF format, scanning documents to PDF files, or converting pictures, PPTs and other information to PDF format, I don't know. So why do we prefer PDF to other formats?

"Portable Document Format" is the acronym for Portable Document Format. This file format was developed by Adobe Systems for the exchange of documents, which is independent of application, operating system and hardware. PDF files are based on the PostScript language image model. It guarantees accurate color and accurate printing, and keeps the original document data intact regardless of the printer or device used to convert the file.

In other words, PDF files possess the following characteristics: they can be used on different platforms such as computers,combine pdfs for free windows, cell phones, Apple devices, and Android or messaging apps like WeChat and QQ. They also preserve the original format and data of a document. This means that no matter how you send or manipulate the file, its content, color, format, font, etc. will remain unchanged. This effectively addresses the issue of documents being altered when sent to a phone. As a result, both document editors and users can confirm the accuracy of the document.

Pictures, PowerPoint presentations, Excel spreadsheets, Word documents, scanned images, etc. after saving in PDF format, can be the most authentic way to save original data information, and the enterprise cannot be altered, so China has grown to be very fond of PDF.
