Practical guidance

Flatten supported PDF form fields into fixed content

Flatten PDF converts compatible interactive form values into their visible page appearance. The resulting sharing copy is no longer casually editable through those fields, which can improve consistency for printing, submission, or review.

Make completed form values non-interactive

Supported AcroForm values become fixed page content rather than editable controls in the flattened copy.

Reduce form-display differences between viewers

Fixing field appearances can help recipients see the reviewed values even when PDF viewers handle interactive controls differently.

Keep the editable source form

Flattening is difficult to reverse and is not encryption. Save the original separately if values may need to be corrected later.
