Flattening permanently merges form fields and annotations into page content. The result is no longer editable as forms or annotations. This cannot be undone.
Your file never leaves this device for this operation.
How it works
- Upload a PDF that contains forms or annotations.
- Read the irreversible flatten warning and confirm you understand it.
- Download the flattened PDF processed in your browser.
Privacy
This tool runs in your browser. Your file is not uploaded to process it.
Limits
- Flattening cannot be undone; keep a copy of the original if you need editable fields later.
- Annotation flatten depends on available local toolkit support; forms use pdf-lib.
- Encrypted PDFs must be unlocked first.
FAQ
- Will filled form values remain visible?
- Yes. Flattening burns field appearances into page content so values stay visible but are no longer editable fields.
- Is this the same as flattening annotation overlays from Add text & shapes?
- Related idea, different scope. This tool targets AcroForm fields and native annotations; Add text & shapes burns its own overlay stamps into content.
