Why fill a PDF form online?

Forms still arrive as PDFs all the time: an application, a tax sheet, a consent or registration form, a contract with boxes to tick. Printing it out to fill by hand, then scanning it back in, is slow and leaves you with a crooked, hard-to-read copy. Filling it on screen is faster, looks neat, and keeps a clean digital original you can send straight back. This tool handles both kinds of form. If the PDF has real interactive fields, you type into the text boxes and click the checkboxes, radio buttons and dropdowns exactly where the form put them. If it's a flat PDF with just printed lines and no clickable fields, you switch to placing your own text and checkmarks anywhere on the page, the same way you'd add text to any document. Either way, when you download you can flatten the result so the answers are fixed in place, or keep it editable if you might change them later. It fills the fields a form already has, rather than building new interactive forms or rewriting the document's existing words, and everything runs in your browser, so the form and whatever personal details you put in it never leave your device.

How do I fill out a PDF form for free?

Open the form and, if it has real fillable fields, type and click straight into them; if it's a flat PDF with nothing to click, drop your own text and checkmarks wherever you need them. Download when you're done, and (by default) the answers are locked in so they show everywhere and can't be changed. It all runs in your browser, so the form is never uploaded.

Frequently asked questions

My PDF already has clickable fields. Can I fill those?
Yes. When a PDF has a real form, you type into its text fields and click its checkboxes, radio buttons, dropdowns and multi-select lists right where they sit, and your answers are written back into the file.
My PDF is flat, just printed lines and boxes. Can I still fill it?
Yes. When there are no interactive fields to click, you drop your own text and checkmarks anywhere on the page, just like adding text to a PDF. It places marks on top of the page rather than turning it into a clickable form. Add text to a PDF
Can someone change what I filled in afterwards?
That's your choice when you download. Flatten (the default) fixes your answers into the page so every viewer shows them and no one can edit them. Keep editable leaves the form fillable with your values pre-set, so you or someone else can still adjust them.
Does it work with every kind of PDF form?
It works with standard PDF (AcroForm) forms, which is what almost every fillable PDF uses. It does not support Adobe's older XFA / LiveCycle dynamic forms, which are a different format that most browsers can't display either.
Can I sign the form as well?
Filling handles the text and tick boxes. To add a signature you draw, type or upload, use the signing tool and place it on the form. Sign a PDF
Are my files uploaded to fill them?
No. The form is filled entirely in your browser, so the document and the personal details you enter are never sent to a server.
