Perguntas frequentes
- How do I fill in a PDF form?
- Drop your PDF onto the page. The tool detects all form fields — text inputs, checkboxes, radio buttons, dropdowns — and shows them ready for input. Type your answers and download the filled PDF. No printing required.
- What if my PDF doesn't have interactive form fields?
- Some PDFs are flat (no fillable fields) — they're meant to be printed and filled by hand. For these, use a tool like a text overlay or convert to image first. SanctumPDF's form filler only works with PDFs that already contain interactive form fields.
- Is my form data uploaded to a server?
- No. Form filling runs entirely in your browser using pdf-lib. Your form data and filled PDF never leave your device.
- Can I save my progress and come back later?
- The tool doesn't persist data between sessions (because nothing is stored). To save progress, download the partially-filled PDF and re-upload it later to continue.
- Is this tool free?
- Yes — fully free with no account required.
- Does it work on mobile?
- Yes. Form filling works in any modern mobile browser. Touch-based input on form fields works the same as desktop.
- Can I flatten the form so the fields can't be edited?
- Yes. After filling, choose to flatten the form before downloading. Flattened forms have the field values baked into the PDF as static content — recipients can't modify them.
