About Flatten PDF
Flatten fillable forms so filled values become permanent page content for printing/scanning.
Upload a fillable PDF. Form fields are flattened so their values become part of the page. After flattening, fields can no longer be edited — ideal for print & scan or archival.
Processing uses the pdf-lib writer loaded from CDN, but your file never leaves the browser.
Where it is used
Contracts, filled applications, invoices — make fields uneditable before sharing or archiving.
