Fill PDF Form

Type into fillable PDF forms — no printing.

Open a fillable PDF form, type into its fields, tick its checkboxes, and download the completed document — no printing, scanning, or uploading to a stranger's server. Pair it with the Sign tool to add your signature after filling.

How it works

  1. Choose or drop the PDF form.
  2. Type into the detected fields and set checkboxes and dropdowns.
  3. Download the filled PDF (optionally locked so values can't be edited).

Common questions

Why does it say my PDF has no form fields?

Some forms are just scans or flat layouts without real (AcroForm) fields. For those, use the Sign tool to place text and signatures anywhere on the page.

What does "lock the filled values" do?

Locking (flattening) bakes your answers into the page so they display identically in every viewer and can't be changed afterwards — recommended when sending the form onward.

Is it safe for tax or medical forms?

Yes — that's the point of SwiftlyPDF. The form is filled by your own browser and never uploaded, so sensitive data stays on your device.

🔒 Like every SwiftlyPDF tool, this runs 100% in your browser. No uploads, no account needed, no watermarks — ever.
