Learn how to use Flatten PDF effectively and explore its features.
The Flatten PDF tool converts interactive form fields, checkboxes, comments, and annotations into static, non-editable parts of the document layout. Essential for finalizing legal forms, locking in questionnaire answers, and preventing further edits before distribution, this utility locks your content securely in place. Operating locally via browser execution, it ensures your sensitive paperwork remains completely private.
