Solution 1Recommended

Use the Predefined Form Fields

When a PDF contains restricted or predefined form fields, the free-form Fill & Sign options are often hidden. You must use the specific fields provided by the form.

PDF creators often lock documents to ensure users only input data into designated interactive areas. When this happens, general marking tools are disabled to preserve the document's structure.

1
Locate interactive fields

Open the PDF document and look for highlighted areas or blue boxes that indicate interactive, fillable form fields.

2
Enter your data

Click directly into the predefined text boxes to type, or click the provided check boxes and radio buttons to mark your selections.

Use the Predefined Form Fields
Restricted Documents: If you cannot click anywhere on the document to type, the document is highly restricted and you must strictly follow the interactive fields provided.

Frequently Asked Questions

Why is the Fill & Sign option grayed out in my PDF?

The document likely has security settings applied by the author that restrict editing, filling forms, or adding free-form signatures. You will need the permission password to unlock these features.

How can I add a check mark if the PDF is not a fillable form?

If the PDF lacks interactive fields but isn't restricted, you can use the 'Add Text' tool to type a check mark symbol (✓), or use the 'Insert Shape' feature to manually draw an 'X' or check mark on the page.

Can I convert a restricted PDF form into a normal editable PDF?

If you do not have the owner password to remove security settings, you cannot edit it directly. However, you can use the 'Print to PDF' function to create a flattened copy of the document, which bypasses form field restrictions and allows you to use standard marking tools.
