About PDF Flatten
Flattening a PDF merges all form field annotations (text inputs, checkboxes, dropdowns, etc.) into the static page content. After flattening, the PDF looks the same visually but the fields are no longer interactive or editable. This is useful for archiving filled forms, preventing modifications, or ensuring consistent display across viewers.
This tool uses pdf-lib's form flattening API. All processing is local — no data is transmitted.
