Hi Pragya, Would you prefer to detect the uniqueness of the pdf entirely, or detect textual changes only? For the first you’d just take the hash of the binary, that allows finding duplicates. For the latter you could apply xdmp:pdf-convert, or xdmp:document-filter. Both should return textual contents as HTML.
Note though that text is not extracted from PDF images..
