FAQs
Why would I flatten a PDF?
Flattening bakes form fields, comments, and stamps into the page so they can't be changed and always display the same way — useful before sharing a completed form.
Can a flattened form still be filled in?
No. Once flattened, the interactive fields become static content. Flatten only after you've entered your final answers.
