Take me for it, each time the end of the training course, there will be a lot of students come around to find me to courseware (teaching with electronic documents). In order to protect my intellectual property rights, I am not willing to give some of the content directly to the students.scanned pdf to word converter online I will first process the PPT content, turn the file into PDF format, and then add some permissions to send him, rather than directly send him a PPT file.

Why do we do this?

These days stay at home, and finally tried all the functions of the PDF, only to realize that many of them have been overlooked, and have not been used before. In fact, it is quite fun to explore office software. Only continuous learning, in order not to be stuck in a rut.

First of all, the difference between PPT and PDF, as well as the benefits of converting PPT to PDF.

First, the difference between Powerpoint and PDF

PPT content in the production software can be modified, pasted and copied at will.

PPT). Presentation creation software PowePoint generated file format, contains text, pictures, charts, animation, sound, movies and other materials.

PDF prominent feature is: without the design and production can be allowed, its content can only see, can not be modified.

PDF is the Portable Document Format (Portable Document Format) for short, meaning "Portable Document Format" (Portable Document Format), you can use the company's free PDF reader or other reader software to view, print and annotation.

In short: PPT is an open file format, PDF is a closed file format.

To this end, there is a specialized handling of PDF format file content software can be used to create, edit and electronic signatures.

Second, when the PPT into PDF, you can also add some of these settings

1 file for encryption, you can open the file by setting a license password (password).

2 file set permissions, you can only see, can not copy the content, can not extract the page and other document protection measures; in particular, can not even print, yes, can not print!

3 PDF files open fast, will not be like when starting a PPT file, it takes a long time.

4 PDF each page can be arbitrarily enlarged and reduced because the text on the page is vector (in layman's terms, you can zoom in and out of the font to keep the edges smooth and pixels will not be lost), will not be blurred because of zooming in and out like an image. In addition, the size of the text is very clear.

5 You can annotate the content, for example, the other party points out that there are places in the manuscript that need to be changed, but you can't change the actual text or images.

But after the conversion of PPT to PDF, many of the original design in the PPT jump animation effects are gone, PDF documents more like electronic paper.

In short, if there is no and the other party (the user) to modify the content of the presentation, in order to protect the fruits of their hard intellectual labor, should be converted to PDF PPT with permission settings!
