Since its inception 25 years ago, PDFs are still one of the main types of documents we use.

Whether you’re viewing a tax form, a contract, or even a little worksheet, they’re probably going to be in the form of PDF. With that being said, there are also times when we need to edit the document or even sign it.

When you’re viewing a contract or a tax form as stated above, you’d most likely be required to fill out your information and leave a digital signature on the bottom. And let’s say for some reason you also want to convert the PDF back to a DOC file. How do you do that?

It might sound very easy, and it really is, but not many people know how to go about doing that.

Well, there are software and online services that can do that. However, I recommend using the former. Here’s why.

Protects privacy

Any work done using PDF software on your computer remains between you and the computer. No matter if it’s a school activity book or a 10 million contract, the privacy remains intact. On the other hand, online PDF services might not be the most trusted sources to upload sensitive documents.

You never know what goes behind the system, and you have no control over it.

No chances of data leakage

The data you enter on your PDF software remains within the system and has no way to spread outside of it. While I expect the online services to be the same, such is not the case every time and with every website.

You’re not fully aware of how your data is being stored or processed. Hackers are one threat, but there are also other concerns like identity theft and fraud.

I’d also like to mention that, if you’ve signed and agreed on a non-disclosure agreement with a company, you’re absolutely not allowed to upload any of those documents to these online PDF services.

24/7 availability

It might not seem like a big thing, but it’s important to note that convenience is necessary. With the software installed on your computer/laptop, you don’t need an active internet connection to run it. It can be done offline.

There are also literally no chances of it being down or under maintenance, unless you purposely wish to update it. You can access it 24/7 on demand.

So, when is it alright to use an online PDF editor? I believe probably when your document isn’t one that is confidential. If you’re editing a PDF that is easily available on the internet, then you can use the online PDF editors. Or else, for private documents, usage of the software is recommended.

Here are the best resources for both of these options, starting with the software.

PDFExpert

A very visually-appealing PDF editor, PDFExpert, is another brilliant option to consider. The name is quite similar to the other one mentioned above in this article, but they’re both different when it comes to functionality.

You can start off by selecting a suitable viewing layout for your convenience and then go on to read, annotate, and edit PDFs. It also allows you to change text and images. Filling forms and signing it are just mere capabilities of this solution.

Conclusion

No matter if you use software or any of the online services to edit your PDF, you can be sure you’ll get the work done with ease. It all boils down to your requirements and how sensitive your document is.

Software is suitable for private files, while an online solution is alright for public and “every day” files that hold no confidentiality.
