Open a fillable PDF and type directly into its form fields — no printing, no scanning. The tool detects text fields automatically. Everything happens in your browser.
Fillable PDF forms contain hidden data fields (called AcroForm fields) that PDF readers can present as boxes to type into. This tool reads that hidden structure directly in your browser, lists every text field it finds, and lets you fill each one before saving a completed copy.
Because detection and filling both happen with pdf-lib inside your browser, sensitive form data — tax details, medical information, job applications — never touches a server. If no fields are detected, the source PDF likely doesn't contain real form data (common with scanned paper forms).
Choose your fillable PDF — the tool automatically detects its text fields and lists them. Type your answers into each field and click Save Filled PDF to download the completed form.
Not every PDF has real fillable fields — some "forms" are just scanned images of paper forms with no underlying field data. Those need to be filled by adding text manually, which this tool doesn't do (only true fillable forms are supported).
Yes, as long as the PDF has real AcroForm fields (most official fillable forms do). If a field isn't detected, the source PDF likely wasn't built as a fillable form.
This version supports text fields. Checkbox and dropdown support may be added in a future update.
No. Field detection and filling happen entirely in your browser using pdf-lib. Your form and its answers never leave your device.
