Cannot sign PDF file with certificate when the PDF file is big

Hi Aspose team,

We found one PDF file is 400MB size and can’t be signed using Aspose.pdf v20.3 lib. Here’s the code and test pdf. Please have a look and let me know if you have any suggestion



I have observed your issue and like to inform that I have created investigation ticket with ID PDFNET-47989 in our issue tracking system to investigate and resolve this issue as soon possible.

Hi Aspose team,

Did you have any progress on it? Will this issue be fixed within 1-2 months? We are going to have the code freeze date of our product.


We regret to inform that the earlier logged ticket is not yet investigated. As the issue was related to API performance, it is complex in nature and will take significant amount to get resolved. We will surely inform you once we have some definite updates regarding its fix. Please give us some time.

We apologize for the inconvenience.


Could you please again share the link to the demo project as we tried to download it and it was no longer available?
