Filling in PDF forms, explained
A PDF form is either fillable (it contains real form fields) or flat (just lines and boxes printed on the page). This filler handles both: it fills real fields directly and turns the blanks on a flat form into fields you can type in.
Is my PDF uploaded?
No. The PDF is opened, filled and saved inside your browser. Your saved details and signatures are stored only in this browser and can be deleted with one click under My details.
How do I fill in a PDF that has no form fields?
Just drop it in. The filler looks for the places you are meant to write: underscores, dotted lines, drawn lines, empty boxes, checkbox squares and labels like "Name:" with space after them, and turns them into fields. For anything it missed, click Text and then click where you want to type.
How does Fill with my details work?
Enter your name, email, phone, address and a few other details once under My details. When you press Fill with my details, every empty field whose label matches (for example Name, Naam, Nom, E-mail, Postcode, Date) is filled in. Labels in English, Dutch, French and German are recognised, and date fields get today's date.
How do I sign a PDF?
Press Sign, or click a signature field. Draw your signature with the mouse, finger or a pen, type your name in a handwriting font, or upload a photo of your signature: the white paper is removed automatically. Then click where it goes, drag it into place and resize it with the corner handle.
Can others still edit the form after I download it?
You choose. Keep fields editable to let you or someone else change the answers later, or lock the answers (flatten) so they become part of the page — best when you send the form to someone.
Which PDFs do not work?
Scanned forms that are only a picture have no lines or text to detect, so place your answers with Text, Tick and Sign. Password-protected PDFs must be unlocked first, and XFA forms made with Adobe LiveCycle cannot be read by any browser: use Text to type on those.
Does it work on a phone?
Yes. Everything works with touch, including drawing your signature with a finger. On a small screen the field list sits under the document.
