What does flattening a PDF mean?

Flattening converts all interactive elements like form fields, annotations, and comments into static content that cannot be edited, making the document appearance permanent.

Why would I flatten a PDF?

Flattening is useful for finalizing filled forms, preserving annotations, reducing file size, and ensuring the document looks the same for all viewers.

Can I undo flattening?

No. Flattening is permanent. Always keep a backup of the original interactive PDF before flattening.
