I have recently modified an excel file and converted the same to PDF. After modifying, I have uploaded the same to an online portal.
However, that online portal system is identifying that i have uploaded a modified file.
Could you please let me know how to avoid my modified PDF to be identified in the portal? I mean, no system should be able to detect that it is a modified file.
Is there any way I can make my PDF file unidentified in the online portal as a modified file?
