I opened my signed PDF in Chrome or Firefox, and the signatures are not being displayed or verified. How do I fix it?

Chrome and Firefox now include PDF viewers built directly into the browser. Unfortunately, these limited viewers only support the bare minimum of PDF features and can’t display or verify digital signatures.

To view any digitally signed PDFs, you must first download a free copy of Adobe Reader. Then you can save the PDFs to your computer and view the signatures with Adobe Reader.

Note that Google Chrome will notify you when a PDF has features it can’t handle (like digital signatures). If you have Adobe Reader installed, you can click the “yes” button directly from Chrome to view the signatures in Adobe Reader.
