Frequently Asked Questions

Why can't I edit or type into the PDF form I received in my email?

If you open the PDF directly within your web browser or email client, it usually opens in a read-only preview mode. To type into it, you must download the file to your computer and open it using a dedicated PDF application that supports form filling.

What happens if I try converting a PDF form to Word to fill it out?

Converting a PDF form to Microsoft Word often breaks the document's layout. Interactive form fields, checkboxes, and alignment can get distorted, making the form difficult to fill out cleanly. It is highly recommended to fill out the form in its native PDF format.

How do I sign the PDF form after filling it out?

Most modern PDF editors, including WPS Office, feature a dedicated Signature tool. You can draw your signature with your mouse, upload an image of your physical signature, or type your name using a cursive font, and then place it directly on the signature line.
