PDFLiner is a set of top editing tools for your PDF files integrated into one online service. With them, you can easily customize your documents on the go, keep them secured and organize your workflow and your interactions with other users. 

The online signature tool is, probably, the most used instrument out of our online editing accessories. Let’s learn its multiple functions and how to work with them. 

There are two ways of signing your PDF file.

1. If you’ve used our service before, you must remember the ‘Sign’ button on your dashboard. It has an ink pen icon and is situated in the upper left. Click on it!

Step 1. Place the ink pen cursor in a place where you’d like to sign the document.

Step 2. Click on the ‘Sign Field’ button.

Step 3. Click on the ‘Add New Signature’ button.

2. Another way of using the ‘Sign’ instrument is through the ‘Add Fields’ tool set. You can launch it by clicking the button with empty fields on it, highlighted green. It’s situated in the upper right corner of your dashboard.

Step 1. Click on the ‘Add Fields’ button.

Step 2. The ‘Sign’ icon comes as one of the first options in the main ‘Add Fields’ menu alongside the ‘Initials’ button. It works just like in the general menu: click on the button, place the cursor somewhere in your uploaded document (or a file from our database) and add a field for the signature.

Now You Have Your Signed PDF

Keep in mind that PDFLiner not just lets you sign any document online and save it momentarily. You can also make your own files with added signature fields and share them with other users so that they could fill and sign them.

To organize your workflow, you need to be logged in to the PDFLiner system and have the person you want to share your documents with logged in, as well. If they are not familiar with the PDFLiner service yet, you can use third-party products for file-sharing.


1. How to sign a PDF on iPhone?

    When you’re a student, you deal with PDFs a lot… Newsletters, various worksheets, official forms you need to fill in and sign, etc… To me, filling out a PDF form used to be among the trickiest and most time-consuming things ever. But then a friend of mine introduced me to PDFLiner, and oh my God, my life has changed since then. It’s easy to use and has so many great features. Just awesome, I love it!
