Flatten PDF
Upload a PDF with a filled-in fillable form - for example one you already filled with PDF Form Filler - and turn its current values into permanent, non-editable page content.
Perguntas frequentes
What does "flattening" actually do?
It uses pdf-lib's own built-in form.flatten() function to permanently burn each field's current value into the page and remove the underlying interactive form field, so the result looks identical but can no longer be edited, refilled or have its values extracted as form data.
Why would I want that?
A flattened PDF is safer to share when you want the recipient to see fixed, final values - it prevents accidental (or intentional) edits to a form you've already filled out and finalized.
What if the PDF has no form fields?
The tool checks first and tells you plainly rather than silently producing an unchanged download.
Is my PDF uploaded to a server?
No, flattening happens entirely in your browser using pdf-lib. Your file never leaves your device.
