PDF flattening is the process of merging interactive form fields (text boxes, checkboxes, dropdowns) and annotations (comments, highlights) into the page content. After flattening, form data becomes non-editable static content, ensuring consistent display across different PDF readers.
Common reasons to flatten PDFs: 1) Ensure form data displays consistently across different PDF readers; 2) Prevent others from modifying filled form content; 3) Meet document format requirements from certain institutions; 4) Reduce file size; 5) Improve compatibility and printability.
