Frequently asked questions
What if my PDF has no form fields?
Then it is a flat document. Use Sign PDF to add a signature or Add Watermark to stamp text on it.
What does 'lock the answers' do?
It flattens the form so your answers become part of the page and can no longer be edited.
Does it work with any PDF form?
It works with standard fillable (AcroForm) PDFs. Some special XFA forms are not supported.
Are my files uploaded anywhere?
No. This tool runs in your browser, so your file stays on your device and is never sent to a server.
