Secure Your PDFs: Flatten Forms and Annotations for Final Submission
At Plainscan, we understand the importance of protecting your PDFs from accidental edits or tampering. That's why we've developed a powerful tool to help you flatten PDF forms and annotations, making them tamper-proof and non-editable.
What is PDF Flattening?
PDF flattening is the process of converting interactive elements, such as form fields, checkboxes, and annotations, into static content. This creates a clean, non-editable PDF that's perfect for final submissions, legal filings, printing, and long-term archival.
Why Do You Need to Flatten Your PDFs?
Before sharing a completed form, you want to prevent recipients from changing submitted answers. Similarly, when preparing legal and compliance documents, you need to lock finalized contracts, declarations, and NDAs before distribution. By flattening your PDFs, you can ensure that your documents are secure and tamper-proof.
