Frequently Asked Questions

Find quick answers to questions about getting the most out of our tool.

What exactly happens when I flatten a PDF document?: Flattening merges all document layers, interactive form fields, annotations, and visual elements into a single static layer. This process creates an uneditable document that preserves the exact appearance while preventing any modifications to content or structure.
Why is PDF flattening important for document security?: Flattening locks all content permanently, preventing unauthorized editing, form field manipulation, or annotation removal. This process is essential for legal documents, contracts, and sensitive materials where content integrity must be guaranteed.
Can I reverse the flattening process to edit my document later?: No, flattening is irreversible. Once layers are merged, interactive elements cannot be restored. Profi PDF recommends keeping an original copy of your document before flattening if future edits might be necessary.
Does flattening affect document quality or visual appearance?: Absolutely not! Flattening preserves all visual elements including fonts, images, colors, and layouts without any quality loss. Your document maintains its professional appearance while gaining enhanced security and compatibility.
How does Profi PDF ensure secure processing during PDF flattening?: Your documents are protected with enterprise-grade encryption, SSL certificates, and secure data transmission throughout the flattening process. Profi PDF maintains Google Safe Browsing certification and automatically deletes files after processing for maximum privacy protection.
