With PSPDFKit, you can generate PDF files from a PDF form.
PSPDFKit for Web offers multiple options for filling form fields programmatically, each with a different set of tradeoffs.
PSPDFKit Server — For persisting, restoring, and synchronizing the form field values across multiple devices without needing to build it yourself.
XFDF — For exporting to or importing from other readers.
Instant JSON — For the most efficient way to export or import changes made.
Manual API — For full control over extracting and saving the values of forms.

The process of flattening form fields consists of rendering them over the background of a page with their current value and removing their data from the document.
