Types of PDF Forms

Interactive PDF forms: Have clickable text boxes, checkboxes, radio buttons, and dropdown menus. You click and type directly into the fields.

Non-interactive (flat) PDF forms: Printed forms scanned or created as images. No clickable fields — you must add text overlays manually.

Filling Interactive PDF Forms

Open the PDF in any modern browser (Chrome, Firefox, Edge) — browsers can fill basic interactive form fields directly. For complex forms with signatures and conditional fields, a PDF tool is needed.

Steps: Open PDF in browser > Click on text fields > Type your information > Print or Save.

For fields that do not work in browser: Use Lazyblink Edit PDF to add text overlays on top of the form fields.

Non-Interactive Form Filling

For scanned or image-based forms, use the Text tool in Lazyblink Edit PDF:

  • Open the scanned form
  • Select the Text tool
  • Click on each blank field area
  • Type the required information
  • Adjust font size to match the form
  • Download the filled form
  • Digital Signatures

    Add a freehand signature using the Draw tool in Lazyblink Edit PDF.

    Draw your signature on a blank area

    Position it over the signature field

    Download the signed PDF

    For legally binding signatures, use dedicated e-signature platforms like DigiSigner, DocuSign, or Aadhaar-based signing.
