How it works
Application forms, tax returns, consent forms and contracts arrive as PDFs with fields in them. Filling one usually means installing a reader, or uploading a document full of personal details to a website. The fields are already in the file; this just reads them out and writes your answers back.
It uses the document's own fields
Text boxes, checkboxes and dropdowns defined in the PDF are listed by name, with anything already filled shown as it is. Your answers are written into those same fields, so the result opens correctly in any reader.
Keeping fields editable, or flattening
Leaving the fields editable means the recipient can change the answers — useful for a draft, or a form you are passing on. Flattening merges the answers into the page so they become part of the document and can no longer be edited, which is what you want for anything being submitted.
When a PDF has no fields
Plenty of documents that look like forms are just printed lines with no fields behind them, and you will be told when that is the case. For those, the PDF signing tool places text anywhere on the page, which is the practical alternative.
What it does not do
This fills fields; it does not apply a digital signature, and flattening is not the same as signing. Where a form requires a certificate-based signature, this is not that.
Fill a PDF form — questions
Why does it say my PDF has no fields?
Because the document has no interactive form in it — it is a printed layout. Use the PDF signing tool to place text on the page instead.
Should I flatten the form?
Flatten if you are submitting it, so the answers cannot be edited. Keep it editable if someone else still needs to fill parts in.
Is this a digital signature?
No. Flattening locks the answers visually but is not a certificate-based signature.
Is my form uploaded?
No. The document is read and written entirely in your browser.
