This tool does not issue a registered seal or a digital signature certificate.
Frequently asked questions
Can I save a transparent background?
The PNG output has a transparent background. If it appears white when inserted into a document, check that the editor supports transparent images.
Does this replace a registered seal or digital signature?
This tool creates an ordinary image file. It does not register seals or authenticate digital signatures. Check the signature method required for your document.
Can the text look different on another device?
The selected system font family may look different across devices. Once saved as a PNG, the appearance of the text in that image stays the same.
