Questions
Is Make PDF Fillable free?
Yes. Create a free NyxPrism account and use it as often as you like.
Are my files uploaded?
Your PDF is processed right in your browser - it isn't uploaded to NyxPrism.
Does it work on Mac, Windows and phones?
Yes. NyxPrism runs in any modern browser, and you can install it as an app on your computer.
Does it automatically detect fields?
Detect blank lines suggests fields for selectable underscore or dash lines. Review every suggestion; scanned forms and drawn boxes need manual placement or OCR.
Can I recover a draft?
Enable Save form draft on this device to store the source PDF and field settings locally. Restore saved draft recovers it; Delete saved draft removes it. It is off by default.
Will every PDF reader show a calendar?
No. Fill PDF Form in this app uses a calendar picker. Other readers may show a standard text field using YYYY-MM-DD.
Can I use an existing form?
Yes, existing fields are preserved. This tool adds new fields; use Fill PDF Form to enter answers. Unlock protected PDFs first. XFA forms are unsupported.
