Flatten PDF Forms Before Submission
Convert interactive form fields to static content for permanent submission
Why Flatten PDF Forms Before Submission?
Before submitting a filled PDF form, flatten it to convert all interactive fields (text boxes, checkboxes, signatures) into static, non-editable content. This prevents anyone from modifying your submitted data after you've sent it.
