Inscribe attempts to reconstruct previous versions of all submitted PDF documents. Whether or not this is possible depends on whether there are any previous versions to recover, as well as the tool used to produce the PDF and the settings used when saving the PDF.

When a previous version is successfully recovered, Inscribe provides a slider to allow you to compare the previous version with the submitted version. Regions of the page where the documents differ are highlighted. Note that making a small change to a PDF often causes small changes to many other areas of the page, so you may see some areas highlighted that appear identical to the human eye.

Note also that the version recovered may not be the original version of the document. Often, edits to documents are made in multiple stages and with multiple tools, and we may only be able to recover an intermediate stage in this process. 

If you wish to download and view the recovered version, you can click the 'Download' button on the left hand side of the page.
