Add real form fields to any PDF: text fields, checkboxes, radio buttons, dropdowns and list boxes. Drag a box where each answer goes, then save. Anyone can then type into the form in their own PDF app. Nothing is uploaded.

Drop it on Fyllyo’s Home screen, or choose Open.
Pick a text field, checkbox, radio button, dropdown or list box. Drag a box where each answer goes. The tool stays on, so you can draw one field after another. To name a field, list a dropdown’s options or make a field required, select it and choose the pencil.
Choose the pencil button to stop editing fields. Then click each field and type, just as the person filling it will.
Choose Save, or Save as… for a copy. The fields are standard PDF form fields, so other PDF apps can fill them.
A text box only sits on top of the page. A form field is part of the form, so the next person can click it and type. Apple’s Preview guide covers filling forms and adding text boxes, not adding form fields (checked October 24, 2026).
Text fields, checkboxes, radio buttons, dropdowns and list boxes, drawn where you want them.
A fillable PDF can become your own form in Fyllyo Paid. Set it up once, then Fyllyo fills it from each client’s documents, on your Mac.
Not with form fields. Preview can add text boxes on top of a page, which is enough to fill a form yourself. But the next person can’t click a text box and type, as they can with a form field.
Yes. Adding form fields is free in Fyllyo, with no account and no watermark.
They’re standard PDF form fields. We made our test form fillable in Fyllyo, filled it and saved it. The saved copy lists all three fields with their values, and macOS’s own PDF engine shows them.
In Fyllyo, choose Form, then the checkbox tool, and drag a small box where the tick goes. Switch to filling with the pencil button and click the box to tick it. In our test, the saved PDF kept the tick.
Yes. Select a field and choose the pencil. You can rename it, add or remove a dropdown’s options, and make it required or read-only. In our test, the saved PDF kept the name and all three options.
Not yet. You draw each field where the answer goes.
No. Fyllyo adds the fields on your Mac, and the file never leaves it.
