SkySignature
Free electronic signature tool for signing and editing PDFs online
About SkySignature
SkySignature is a web-based electronic signature platform that lets individuals and businesses sign, edit, and verify PDF documents without installing any software. Unlike many e-signature tools that only sign portions of a document, SkySignature signs the entire file to prevent tampering. It features an exclusive "type anywhere" capability for filling out forms, drag-and-drop signature placement, and a verification algorithm to detect document tampering. Available as a free Community Edition and a paid Professional Edition, it suits freelancers, small businesses, enterprises, and government users.
