Document limitations
This is a visible mark, not identity verification, certificate-backed signing, or a promise of legal validity. Saving rewrites the PDF and invalidates existing cryptographic signatures; forms, annotations, bookmarks, or metadata may also be affected.
Questions and troubleshooting.
Is this a certificate-backed digital signature?
No. It adds visible image content only; it does not cryptographically seal the document, verify identity, or promise legal validity.
Can I apply it to selected pages?
Yes. Enter pages or ranges such as 1-3,5 and position the mark in the preview.
Are my PDF or signature uploaded?
No. Both are processed in temporary browser memory and are not sent to EkkySoft or saved in browser storage.
Will an existing digital signature remain valid?
No. Rewriting a digitally signed PDF invalidates its cryptographic signature. Keep the original signed file.
