Frequently Asked Questions

Why should I flatten a PDF?

Flattening a PDF locks in form data, prevents further editing of annotations, and ensures the document prints exactly as it appears on screen.

Can a flattened PDF be un-flattened?

No, flattening is a permanent process. We recommend keeping a backup of your original interactive PDF.

Does flattening reduce file size?

Often, yes. By merging layers and removing interactive form fields, the overall structure becomes simpler and smaller.
