What does flattening a PDF mean?

It converts interactive fields and annotations into ordinary page content, making their current appearance permanent.

Can I edit form fields after flattening?

No. Download and keep the original if you may need to change field values or annotations later.

It should not. Moletools verifies that the output page count matches the input before returning the file.

Turn interactive form fields and annotations into fixed page content so the document displays consistently when shared or printed.

Generated appearances, forms, and annotations are merged into page content for more consistent viewing.

Recipients see the filled values without needing a PDF viewer that supports interactive forms.

Flattened fields are no longer editable, so keep the original PDF if future changes are required.
