How do I create a fillable PDF form?
To create a fillable PDF form, open your PDF in PDF forms, select Detect fields automatically, keep the fields you want and save. The detector looks for blank lines, underscores, boxes, check boxes and labels that end with a colon, and proposes a field for each one with a name taken from its label. Adjust them on the page, or add text, check box, radio, drop-down, date and signature fields by hand.

What can I set for each field?
Every field has a name, tooltip, default value, font size, colours, alignment and maximum length, and can be marked required or read-only. Set the tab order by rows, by columns, as in the original or in your own order. The blue shading you see is a viewer highlight that shows where to type; it is not printed.
Can I fill in the form here too?
Yes. Open a form and type in the highlighted fields; required fields are marked, and before you save we tell you which ones are still empty. Choose Flatten after filling to turn the answers into regular page content, or see Fill PDF form. To sign as well, use Sign PDF.
