Frequently asked questions
Common questions about the Fill PDF Forms.
What kinds of form fields are supported?
Text fields, checkboxes, dropdown menus and radio-button groups — the standard AcroForm field types used by government forms, applications and invoices.
What does "flatten" mean?
Flattening bakes your answers permanently into the page and removes the editable fields, so the recipient sees a clean completed document that cannot be altered. Leave it off if you want the form to stay editable.
My PDF has no fillable fields — what now?
Some PDFs are just static pages that look like forms. Open the file in our free PDF editor instead, where you can click anywhere and type your answers over the page.
Is my form data private?
Completely — the PDF and everything you type stay in your browser. Nothing is transmitted, stored or logged.
