PDF Forms has two modes. Fill detects the form fields already in a PDF, such as text boxes, checkboxes, radio buttons, dropdowns and list boxes, and lists them in a side panel so you can complete an application or registration form without printing it. Turn on 'flatten after filling' if the values shouldn't be changed afterwards.
Create lets you draw new fields onto the pages: text fields, checkboxes, dropdowns and date fields. It's a quick way to turn a plain PDF, like a sign-up sheet or an order form, into something others can fill in electronically.
Everything runs in your browser. Values are saved into the PDF itself and nothing is uploaded. One limitation to know: XFA forms (dynamic forms created with Adobe LiveCycle Designer) aren't supported; they typically open with a 'please wait' message in non-Adobe viewers.

Frequently asked questions
Why aren't any fields detected in my form?
The PDF may have no interactive fields (it was designed to be printed), or it may be an XFA form. For plain PDFs, use Create mode to add fields, or type onto the page with Edit PDF.
What is an XFA form?
A dynamic form format created with Adobe LiveCycle Designer. It's not supported here; such forms usually need Adobe Acrobat or Reader to fill.
Will my answers be saved in the PDF?
Yes. Values are written into the PDF's form fields, so they appear when the file is opened in other PDF readers.
Should I flatten after filling?
Flatten if you're submitting a final version and don't want the values changed. Leave it off if you or someone else may need to edit the answers later.
Is my form uploaded?
No. Filling and creating fields both happen in your browser, and the PDF stays on your device.
