How to Sign PDF Online

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.

E-Sign PDF with our "Add Sign" tool

Step 1. If you’ve used our service before, you must remember the ‘Add Sign’ button on the upper toolbar. It has an ink pen icon. Click on it!

Step 2. "Signature Wizard" will open. Click on the ‘Add New Signature’ button.

Step 3. Choose how you want to Generate your signature.

Step 4. Place your signature where you want it to be on your document.

Use a "Signature Field"

Another way of signing your document electronically is through the ‘Signature Field’. If you would like to sign one of our fillable forms you will most likely find the "Signature Field" on your document right where you should sign it.

Step 1. Click on the ‘Signature Field’.

Step 2. Chose a signature that you already have or click on "Add new signature" button.

Step 3. Make a signature using one of the three instruments and click "Save".

After that, your electronic signature will appear on the document you can control its size by using the controllers right below the toolbar.

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.

    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!
