Private by design
Filling a form in RaptorPDF happens in your browser on your own device, so the values you enter are not uploaded to our servers. That keeps the process fast and keeps your details on your own machine. As with any online tool, avoid uploading highly sensitive documents unless you are comfortable using a web-based form filler.
