If you are an office tech rooky office world as a user of Word, Sheets, PDF, or Slides, you might have thought, "whoa, that seems difficult". Whenever you come across a task that needs you to convert a PDF into a Word Document, to Excel, or simply convert one type of file to another using this piece of software, you shouldn't get lost in the panic. Signing a PDF is also among the most accessible and valuable things you could do with a PDF editor.

Maybe many of us that have ever stood before such a task know that in the good ol' days, most of the information, use cases, and support were challenging to find for the basic user. However, now it's pretty easy to get involved with a PDF editor. And it's not scary at all. It's exciting because of the app's intuitive interface and simple, friendly instructions (like the one you're reading now).

Even if you don't need it for your everyday work, a PDF editor might come in handy if you want to create and edit the content that needs to look beautiful, neat, and above all - professional.

Why you should get to know PDF Extra editor when digitally signing documents

Well, the reasons are more than a few. Imagine you are applying for a job, your dream job, and your future employer sends you a PDF document you need to sign. A few years back, most of us would print the document, sign it by hand, then scan it, upload it to a digital device, and then send it back to the future employer. We can all admit that it sounds like a whole-day time-consuming journey because you probably don't have a scanner at home, and you don't have a printing device, as well. That is why the availability to digitally sign a PDF is more than welcome! With PDF Extra, you can easily create your personal file signatures and use them to sign all types of PDF documents without using any physical hardware. Not even a pen.

This way, it will be easier to create a signature for PDF than patting yourself on the back after a well-done job :)

What's the difference between quick signing and digital signing of PDF

Of course, there is a difference between quick signing your PDF and digitally signing it, and it is pretty vital to draw the line between these two types of signatures. Using a quick signature, you simply add an annotation to your document. When you add a digital signing to PDF documents, the signature is associated with your digital certificate as a user.

For starters, if you need a higher level of security when using and sending signed documents, the digitally-signed ones bring out a lot more protection to the content and the owner. Signatures based on a certificate are more or less like the regular signing of a PDF. However, there’s a lot more than meets the eye. A digital signature with a certificate is difficult to forge. The reason - it consists of additional encrypted information which is unique to the owner/signer. Data that can be verified and can prove to recipients if the file was modified after the signer initially signed it.

The digital signature flow is simple with PDF Extra:
1. Open the document.
2. Click “Protect”.
