How do I fill in a PDF form using Fill & Sign?

Open your PDF in Acrobat. Go to 'All tools' > 'Fill & Sign'. Click on a form field to type directly, or click anywhere on a flat form to add a text box. Type your information and adjust the text box if needed.

What should I do if my PDF form won't save content after filling it in Acrobat Reader?

Check if the form is a 'Reader-Extended PDF'. If not, saving filled data is usually not allowed in free Reader. Contact the form creator and ask them to save the PDF as a Reader-Extended document. Consider using the full Adobe Acrobat program, which generally allows saving filled forms regardless of Reader-extension. Print the filled form to a PDF if saving the interactive data is not possible, as a workaround to keep your changes.

about this task

Open your PDF in Acrobat.
Go to 'All tools' > 'Fill & Sign'.
Click on a form field to type directly, or click anywhere on a flat form to add a text box.
Type your information and adjust the text box if needed.

An interactive form has specific areas, called form fields, where you can click and type your answers directly. Acrobat recognizes these fields. A flat form, however, is like a picture of a form; it has no built-in fields. With flat forms, you use the Fill & Sign tool to place new text boxes anywhere on the page to add your information, making it flexible for any document.

You often cannot save data in Acrobat Reader if the form's creator did not enable this feature. The form needs to be saved as a 'Reader-Extended PDF' by the person who made it. If it's not extended, Reader lets you fill it, but not save the changes. This is a permission set by the form's owner, not a bug in Reader.

If you cannot type into a form field because it seems read-only, it's possible that the 'Read Only' property for that field is checked. You would need to uncheck this property to enable typing. This is often an issue with the form's settings or how it was created, and sometimes requires the full Acrobat program to change these properties.
