Qu'est-ce que Aplatir PDF ?
PDFBasic's Flatten PDF tool merges all interactive layers (form fields, annotations, comments, signatures) into the base PDF page content, creating a flat, non-editable version. This "bakes in" all overlaid content permanently, preventing further editing while preserving the visual appearance. Flattening is essential for document finalization, legal submissions, and archival.
Comment utiliser Aplatir PDF
Upload your PDF with interactive elements (forms, annotations, signatures). Click "Flatten" and our tool merges all layers into the page content. Download the flattened PDF — all interactive elements are now part of the page image and cannot be edited.
Quand utiliser Aplatir PDF ?
