If you want to create a PDF file on your Windows 11/10 laptop or desktop, then it can be done using a third-party PDF Editor software. There are both paid and free PDF Creator software for Windows PC.

To add your signature to another spot or a subsequent PDF, click on the Sign icon and choose your saved signature. After you’ve added text and signed the PDF, save the file.

The good news is that alt text — short text descriptions usually under 100 characters — is usually easy to add to a PDF document in whatever program you use to create the PDF.
