Convert editable form fields, signatures, and annotations into static page content so no one can alter your finalized PDF.
When you send a completed application form, signed agreement, or stamped price quote, interactive AcroForm fields and floating annotations can still be edited or deleted by the recipient. Our Flatten PDF tool merges form inputs, signatures, watermarks, and notes directly into the page content. Choose vector form locking to keep body text selectable, or full-page raster flattening at 150 or 220 DPI for a non-copyable print-ready document. All processing happens locally inside your web browser for complete privacy.
No. Flattening converts interactive text boxes, checkboxes, and dropdowns into static page graphics that cannot be clicked or modified.
Vector flattening locks interactive form fields while keeping normal page text selectable, whereas Raster flattening turns every entire page into a locked image.
Some government and university portals or printers ignore interactive form layers; flattening ensures every filled entry and signature appears on the page.
