Let’s get straight to the point and learn how to create a fillable form in PDF Liner. Here are all the steps:

  2. Add fillable fields – to do this, click the green “Add fields” icon in the top right corner to open the fillable fields editor. Here you can choose fields for text, numbers, dates, signatures, and more. Simply click the needed item in the toolbox on top to use it.

  1. Download or share your fillable form – check if everything is ok, and then click the red “Done” button to download the form or share it. In order to keep it fillable, save it only in PDF format as JPG is a non-interactive format. You can also share a direct link to the form without downloading it. That’s very useful when you need to request a signature or a certain reply quickly.
