Interactive vs Flat Forms
Interactive PDF forms have designated fields you can click and type into. Flat forms are just images of forms โ you need to overlay text on top of them. Both types are common in government, legal, and business contexts.
Filling Interactive Forms
Interactive forms have clickable fields โ text boxes, checkboxes, dropdown menus, and radio buttons. Click each field and enter your information. Most PDF viewers support this natively without any special tools.
Working With Flat Forms
Flat forms require adding text boxes on top of the form image. Position each text box carefully to align with the printed fields. Matching the font size to the form's design (typically 10-12pt) creates a professional appearance.
Adding Signatures
You can add signatures to PDFs in several ways: drawing with a mouse or trackpad, uploading a signature image, typing your name in a script font, or using a digital certificate for cryptographic signing.
Saving and Sharing
After filling, flatten the form to prevent further editing. This merges the form fields with the page content, ensuring the filled data appears correctly on any viewer. Always keep an unflattened copy for your records.
