About this app

PDFun helps you sign PDF documents, fill interactive forms and add text from your phone.

SIGN DOCUMENTS
Draw your signature with your finger, choose an ink color and place the signature on your PDF.

FILL PDF FORMS
Enter values in supported interactive form fields and apply them to your document. You can also lock fields after filling.

ADD TEXT
Add your name, email, dates or other text. Adjust text size and choose a color.

SAVE AND SHARE
Save an edited copy of your PDF and share it using the apps available on your device.

ON-DEVICE DOCUMENT PROCESSING
