What does flattening a PDF mean?

Flattening a PDF converts form fields, annotations, and interactive elements into static content. This makes the PDF non-editable and ensures the visual appearance remains consistent across different PDF viewers.

Will my PDF look different after flattening?

The visual appearance should remain the same. Flattening only converts interactive elements to static content, preserving the document's visual integrity.

Can I still edit the PDF after flattening?

No, once a PDF is flattened, form fields and annotations become part of the static content and cannot be edited. If you need to make changes, you'll need to use the original PDF before flattening.

What happens to form field data when flattening?

Form field data is preserved visually in the flattened PDF. The values you entered in form fields will appear as static text, but the fields themselves will no longer be interactive.

Can I flatten password-protected PDFs?

Yes, you can flatten password-protected PDFs. The flattening process will maintain the document's content and structure while converting interactive elements to static content.
