How do I fill a PDF form without Adobe?
Drop the PDF in. Every fillable field appears as an input — fill them in and download the completed PDF.
My PDF has no fields — what can I do?
Some PDFs are just scans or flat documents. Use Edit PDF to type text anywhere on the page instead.
What does Flatten do?
It turns the answers into part of the page so they can't be changed — best when submitting a final copy.
Can I sign the form?
Yes — after downloading, add your signature with PDF Signature.
Does it work with XFA forms?
XFA forms (made with Adobe LiveCycle) can't be filled in browsers; the tool tells you if your file is one. Open those in Adobe Acrobat Reader.
Is my form uploaded?
No. Your PDF and answers never leave your device.
