Another way of signing your document electronically is through the ‘Signature Field.’ If you want 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’ and select ‘My 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 add a fillable signature field to your PDFs and share them with other users so that they could fill and sign them. Also, you may send the already filled-out document to another person to sign it; they don't even need to be registered on the site!

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 unfamiliar with the PDFLiner service, they can use third-party products for file-sharing.
