FAQs

  • Q: How do I expand a text box in a fillable PDF?
    You can only expand it after you add a fillable PDF text box before saving the file. Just drag the bounding box corners. Once you've exported or saved the fillable PDF, you can no longer expand the text field size.

    However, you can change the box properties to have more lines to type text. In Acrobat Pro, right-click on the text box, open the properties window, make “Multiline” and Scroll long text or Scrollable selected under the “Options” tab. In this curving way, you can get the fillable field larger. This configuration can also solve the PDF text box not wrapping or disappearing in PDF issue.

  • Q: How do I enable editable fields in a PDF?
    When you have added a fillable text box in a PDF file, open the file with a PDF reader that supports forms. Once you’ve opened a fillable PDF in Adobe Acrobat, Google Chrome, or even some online programs, the editable fields will come up automatically. You can also remove a fillable text box in a PDF with these tools by the form editing feature or printing operation.
  • Q: How do I add fillable check boxes in a PDF?
    The software that allows you to add a fillable text box in a PDF usually can also perform checkbox insertion in a similar workflow. In the LibreOffice Draw, choose View > Toolbars > Form Controls, select the checkbox icon, and draw a rectangle to add the fillable box. Right-click to access the properties option and delete the box label or name. From Sejda, upload your PDF to the form creator page and click the checkbox button to add one.
