How to use Flatten PDF (Forms, Comments and Layers)
Choose a PDF, pick “form fields only” (keeps text) or “everything as images”, then flatten and download.
How it works
Form fields are flattened with pdf-lib into page content; in image mode every page is rendered with its annotations by pdf.js and rebuilt as an image.
Example
A filled application form flattened in “form fields only” mode keeps sharp, selectable text but its fields can no longer be changed.
