Fill PDF Form — Frequently Asked Questions
What kinds of PDF forms does this support?
Standard AcroForms — text boxes, checkboxes, radio buttons, dropdowns, listboxes, and push buttons. If your PDF has fillable fields, this tool detects them.
What does 'flatten' do?
Flattening bakes filled values into the PDF's content stream so recipients can't edit them. Use it when you're done filling and ready to share.
Does this support XFA forms?
Not yet — XFA is a different form format used by some Adobe-only PDFs. If your PDF shows 'Please wait…' in Adobe Reader, it's likely XFA.
Are my filled values saved to any server?
No. Everything happens in your browser. Your PDF, the values you type, and the final output all stay on your device.
