Frequently Asked Questions about Flatten PDF
What does flattening a PDF do?
It converts interactive elements (form fields, annotations) into static content that cannot be edited.
Will I lose any data?
No — form field values are preserved as static text. The data remains visible but is no longer editable.
Is this useful for sharing PDFs?
Yes, flattening ensures the recipient sees the document exactly as intended without being able to modify form data.
