@hung.hoangmanh,

Can you please share the source and target PDFs with us?
Do you face this issue when comparing a particular set of PDFs? Or it is common for all the PDF documents?

@hung.hoangmanh,

Did you deploy/run this showcase project on server?
If yes, did you make any change in the project?

Because the above screenshot has a different layout.

@atirtahir3
No, i don’t deploy above showcase project on server.
I only base on this sample to do my project. I don’t know why there is a difference between my local version and my deploy version. Is it related to trial license or another reason? It is difficult to detect and find bug or your lib.

@hung.hoangmanh,

Do you face this issue with all PDF documents?
Can you please share problematic PDF files and above mentioned word/excel files along-with resultant/output document? Also share your license expiry date.
