No fields were found in my form.

Then it is not a real form — it is a flat page with printed lines that look like fields. Use Edit PDF to place text where the boxes appear.

What does flattening do?

It bakes your answers into the page so they become part of the document and can no longer be edited or cleared. Use it when sending a completed form to somebody.

The form has no fillable fields — what now?

Then it is a printed form saved as a PDF. Use Edit PDF to type on top of it, which is the same thing you would do with a pen.

Will the recipient be able to read my answers back out?

Yes. Filling real form fields keeps the values as data, so whoever receives it can extract them rather than retype them.

How to use Fill PDF Forms
