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.

  • Helen Cohen
    Self-Employed Accountant
    Wow, this tool is amazing!!! I use it on a regular basis to edit and digitally sign a variety of tax forms and accounting docs. It gets the job done wonderfully, and, what’s even more important, it saves me heaps of time!! I also love that via this tool, I can send my clients forms for e-signature. Super convenient!!
  • Owen McKenzie
    Insurance Agent
    I e-sign all kinds of insurance-related stuff with PDFliner. What I particularly like about its e-signature feature is that you can create handwritten signatures and sign lots of various docs in a matter of moments. Just draw your signature using your mouse or touchscreen and you’re all set. Piece of cake! Kudos to the team behind this excellent tool!
  • Monica Navarro
    HR Onboarding Specialist
    Security is my primary concern when it comes to working with digital signatures. I used to approach the whole digital-signature thing with a healthy dose of skepticism, but I feel safe and relaxed now that I work with Pdfliner. Their policies and the company, in general, are very reliable, while their e-signature feature is possibly even safer than a hand-written one. It matters a lot to me. Been working with them for over a year, so yeah, I know what I’m talking about.
