What is PDF Flattening?
PDF flattening is the process of merging form fields, annotations, and layers into the permanent content of the PDF pages. After flattening, these elements cannot be edited; their appearance is fixed.
PdfMetric's PDF Flattening tool embeds form and annotation data into page content to create a fixed appearance. Processing is done securely on the server. Ideal results for printing and archiving are achieved.
When Should You Use It?
- Forms: Lock filled form fields and prevent further changes
- Annotations: Make comments and markings permanent
- Printing: Ensure all forms and annotations appear when printing
- Archiving: Preserve the final state of documents
Advantages
- Fixed content: Forms and annotations become non-editable
- Consistent printing: All elements appear in print
- File size: Redundant layers are merged; size may decrease in some cases
- Compatibility: Better compatibility with older viewers
Frequently Asked Questions
No. Flattening is permanent. Form fields and annotations can no longer be edited. Back up your original file if you plan to make changes later.
