Flatten PDFs

The Flatten feature allows users to convert all interactive elements and form fields in PDF documents into static content to ensure document cleanliness and consistency. This is useful for users who need to standardize or archive PDF documents. For example, in legal documents, users may need to flatten form fields for archiving and auditing; in academic papers, users may need to flatten interactive elements for submitting formal versions. Additionally, this feature can be used to flatten notes and comments in PDF documents for better management and distribution. By using the flatten feature, users can ensure document cleanliness and consistency and easily manage and distribute them.
