Why Flatten PDF Documents?
Prevent Form Editing
Lock completed PDF applications, tax declarations, and contracts so recipients cannot modify filled text fields or checkmarks.
E-Filing & Print Compatibility
Government and court filing portals frequently reject interactive PDFs. Flattening guarantees compatibility across all PDF viewers and printers.
Zero Cloud Uploads
Flattening executes 100% in your browser. Sensitive financial and legal information never traverses the Internet.
Frequently Asked Questions
What does flattening a PDF do?▾
Flattening takes interactive form fields (text inputs, checkboxes, dropdowns) and annotations (signatures, sticky notes, highlights) and merges them permanently into the base PDF layer so they cannot be edited or modified.
What is the difference between Vector Form Flatten and Full Print Flatten?▾
Vector Flattening locks form fields while preserving razor-sharp text and small file size. Full Print Flattening rasterizes the entire page into a high-DPI image, preventing any text extraction or script tampering.
