Flattening a PDF converts interactive elements like form fields, annotations, and comments into static, non-editable content. The visual appearance remains the same, but users can no longer modify or fill out the form fields.
Flattening is useful when you want to preserve form data permanently, share a filled form without allowing changes, reduce file size, or ensure the document displays consistently across all viewers.
Yes! SwiftPDFLab supports batch processing. You can upload multiple PDF files and flatten them all at once, saving you time when processing large numbers of documents.
No, flattening is permanent. Always keep a backup of your original PDF if you might need the editable version later.
