Why Flatten a PDF?
Flattening a PDF converts all interactive elements — including fillable form fields, text annotations, digital signatures, comments, highlight markups, and separate layers — into static, non-editable content that is permanently embedded into the page. This is an essential step when preparing final documents for official distribution or legal archival.
Common use cases include finalizing digitally signed contracts so signatures cannot be removed, preparing completed tax forms for submission, locking down filled application forms before archiving, ensuring annotation markups are permanently visible in shared review documents, and reducing document complexity to avoid rendering issues during printing.
