You can verify that signed documents created using our platform were not altered or tampered with. This can be done by opening any document signed with Xodo Sign in Adobe Reader on your local machine.
A green checkmark indicates that the document has been signed correctly, and you are looking at the original version.

An orange warning sign indicates that the document has been amended or slightly altered after it signing. For example, somebody used a text-highlight tool or a touch input to draw handwritten notes on top of the document. In this scenario the document can still be valid and legally binding, however, it cannot be guaranteed that it's comparable to the original file. Be careful!
A red x-sign means that the document is invalid. Someone tried to remove the signature or edit the PDF file source with specific tools, which are trying to break the write-lock on this document. This means the document is not legally binding anymore.
