My PDF has blanks but the tool finds no fields — why?

Then the form is a scan or a flat layout without built-in fields. Use Edit PDF to type text anywhere on the page instead — this tool fills real (AcroForm) fields only.

Should I flatten the completed form?

Flatten when submitting a final version — the answers become part of the page and cannot be edited. Skip it when someone downstream must change or add entries.

Do I need Adobe Acrobat for any of this?

No — detection, filling and flattening all happen here in the browser workflow; the completed PDF opens in any reader.

Fill PDF Forms

The form arrived as a PDF; the instructions say "complete and return." Without Acrobat, that used to mean printing it. This tool reads the form's actual fields — every text box, checkbox and dropdown the author built in — and gives you one input per field. Type the answers, download the completed PDF. Free with fair daily limits.

Real fields, not text floating on top

Overlay editors let you type boxes of text near where the blanks are. This is different: the tool detects the PDF's built-in form fields (AcroForm), so your answers land in the fields themselves — correctly positioned, correctly formatted, visible to whatever system reads the form later.

Flatten when it must not change

A completed form usually should stop being editable. The flatten option bakes your answers into the page content — what you submitted is what everyone sees, and no reader can quietly revise a field afterwards. Leave it off if the recipient needs to continue editing.
