Frequently asked questions
How does form detection work?
PDF Bunker reads the interactive fields built into your PDF — text boxes, checkboxes, dropdowns, and radio buttons — and lays them out so you can fill each one.
Is my form uploaded to fill it in?
No. The form is read and filled entirely in your browser, so your answers and your file never leave your device.
Does it work offline?
Yes — once the page has loaded, you can fill a PDF form with your internet disconnected.
Do I need an account?
No. Anonymous users get up to 5 operations per day; a free account gives unlimited basic operations.
