Wypełnianie formularzy PDF

Upload the PDF and it opens in an embedded viewer that turns the form fields into live inputs, so you can type into text boxes, tick checkboxes, and pick from dropdowns and radio buttons. If nothing becomes editable, the document has no real form fields; add some with Create PDF Form first.

XFA is an older XML-based form format that Chrome and most online tools can't render, which is why those forms show up as blank pages elsewhere. This form filler and Firefox both support XFA, so you can fill and save those forms here.

Click Save & Download Filled Form and the viewer writes your entries into the PDF's form fields and downloads the file. The values are stored in the fields themselves, so they show up in other PDF viewers, not just this one.

This tool fills fields only. Download the filled PDF, then open it in Sign PDF to add your signature where the form expects one.

The fields stay editable in the downloaded file, so a recipient could change them. To lock the answers in place, run the filled PDF through Flatten PDF, which turns the fields into fixed page content.

Download the form with whatever you've filled in so far; the values are kept in the fields. Upload that same file again later and the viewer shows your earlier entries ready to continue.

If the PDF requires a password to open, the tool prompts for it before loading the form. The downloaded copy is saved without that password, so protect it again with Protect PDF if the form needs to stay locked.

No. The form is rendered by a PDF.js viewer embedded in the page, your entries are held in that viewer's memory, and the completed PDF is written and downloaded on your device. Nothing you type is transmitted, which is the point when the form holds tax, medical, or ID details.
