Filling forms​

  • Form fields are detected automatically — text fields, checkboxes, radio buttons, and dropdowns.
  • Tab between fields for quick entry.
  • Field validation is honored where the PDF specifies it.

Field tools​

Beyond typing into fields, you can place marks where a form needs them:

  • Checkbox and radio, including ticked and crossed variants
  • Standalone tick, cross, and bullet marks
  • Adjust text field font size with the on-field controls

Saving​

Save your filled form as a new PDF or overwrite the original. See Save Options.
