Form XObjects enable you to reuse recurrent objects throughout a PDF document in order to reduce its size. You can add text, images, vector elements and more to a composite object and reference it multiple times.

Leverage textboxes, radio-buttons, listboxes and similar controls to make the PDF document interactive. In this way you enable your user to fill and edit data in the PDF document. Once the users fill the required data, you can also flatten the forms. The form field flattening feature removes all fields but preserves their content in the document to disallow further modifications.

To ensure better security the PDFProcessing supports the following encryption algorithms, which can be managed using the EncryptionType property:

• For import: RC4 (V2), AES-128 (AESV2), AES-256 (AESV3)
• For export: RC4 (V2), AES-256 (AESV3)

Additionally, you can encrypt PDF documents with a password to protect sensitive information and prevent unauthorized users from accessing your files.
