Select Fill & Sign

A menu list will appear. Tap on the 'Fill & Sign' option from this list.

Use the signature tool

The Fill & Sign tools will now display at the top of your screen. Select the signature tool (usually a pen icon) to draw or place your signature onto the PDF.

Frequently Asked Questions

Why is the Fill & Sign option grayed out in Acrobat Reader?

If the Fill & Sign option is grayed out, the document is likely secured with a password, digitally certified by the creator, or has restricted editing permissions that prevent modifications.

Can I save my signature in Acrobat Reader for iOS?

Yes. Once you create a signature using the Fill & Sign tool, the application saves it securely on your device, allowing you to quickly apply it to other PDFs in the future without redrawing.

How do I change the color of my signature in the mobile app?

Tap the signature tool, place your signature on the document, and select the color palette icon in the floating menu that appears above the signature to change its color.
