What do you think are the biggest advantages of PDF documents?

First of all, let me talk about my understanding of PDF.

In college, when a teacher receives an assignment, he or she complements the student's assignment by requiring the student to use the PDF format.

After work, the boss requires all external documents to be in PDF format.

The advantages of PDF are also clear:

【 not scrambled 】

I studied engineering when I was in college. circuit printing service There are many formulas in my homework. I remember once I submitted a text version of a formula. Before I submitted it, I checked the formula to see if there were any typos. The teacher immediately replied that word was garbled and sent it to her in PDF again, because she saw that the formula in word version was completely garbled, and later found that we used different word versions. Because of this problem, I used PDF file format for subsequent submission.

【 High confidentiality 】

At the beginning of my work, I used the text version to send attachments and CC to the leader. As soon as the e-mail went out, my boss called and asked why I was sending text instead of PDF. And told me that subsequent external email attachments should be pdfs, PCB fabrication company one to ensure that the layout is not cluttered, and the other to prevent others from editing and modifying the data, which is essential. Here's the first tip I learned on the job: send external e-mail in PDF format.

However, a coin is always positive and negative,china PCB and the advantages you see also have disadvantages. For example, PDF can ensure that it is not garbled, but it will be very troublesome if you want to modify PDF, because students are forbidden to modify PDF, so you can't copy all the data into word, and then convert it into PDF after modifying the information yourself.

So I wonder if there is any software that can be modified directly in PDF?

Then I have to recommend it. Its one-second PDF editing is really good.

In particular, it can be used in PDF versions such as text editing, deleting text, adding text, modifying text... ... It can be done, it is unbeatable operation, and the star PDF also has colorful annotation features, including highlighting, wavy lines, deleted lines, comments and other forms.

Wanxing PDF has intimate functions such as split extraction, which is super easy to use. The next time the leader makes unreasonable demands on you, for example, I only need page 1, page 3, page 6 ... or just odd pages and even pages, you only need to click a few times to meet his demands and make him sit up and take notice.

For those of us who deal with forms regularly, it also provides a social benefit that can be directly influenced by identifying data in the field of forms, which is the equivalent of businesses being able to fill out pdfs like Excel forms, which is really convenient, it also improves the extraction of data from tables. For students who need teachers to process this data, developing this data is, in general, a big reward
