About Signature App

The image electronic signatures allow to sign document with eSign application. Note, the signed Png document keeps signatures as supported document elements, such as text, labels, stickers, images, hidden metadata information and digital certificates that verify document content. The Png document signed with digital certificates could be verified for any changes of its content. If there were some changes made to signed document then verification process will detect it and certificates will be not valid. To add various electronic signatures, you need to select one or more Png documents, then in application select one from the existing signature templates like Text Stamps, Images, Handwritten signatures, Barcode, QR Code or digital certificate to sign, drag the signatures across the document pages. The documents are stored in a secure storage. You can upload it from any platform, mobile or another device, on any Windows, MacOs, Linux or Android platform.
