Flatten PDF

Bakes a PDF's filled form fields into permanent page content so the values can no longer be edited.

Pick a PDF, then flatten it. Form fields you see reported first stay baked into the pages.

Flattening turns each form field and its drawn value into ordinary page content, so no PDF viewer can re-select or re-type what you filled in. It is one-way: keep the original if you expect to edit the form again. A digital signature stops being valid once its document is flattened, and XFA-only forms are beyond this engine; when one is detected the report says so. Visual fidelity is the appearance streams' own, not guaranteed pixel-identical to your viewer's on-screen fill. Everything runs in this tab; the document never leaves your device.
