Asynchronous File Conversions C#

Is there any asynchronous File conversion method?
When processing large word, Excel, and PPT documents to pdf (100+ pages), It takes 20 to 25 sec.

Is there any way to add Digitally Sign or Draw Rectangle on every page on pdf document (200+ pages) using single processing?

Thank you for contacting support.

We would like to update you that all Aspose APIs are managed code and they support asynchronous/parallel file conversions provided one instance or thread is working with only one document.

Moreover, please visit below documentation articles for your kind reference.

We hope this will be helpful. Please feel free to contact us if you need any further assistance.

We have around 100+ rectangles to be placed as Image onto multiple pages of same pdf file.

Currently, I am looping through each rectangle and placing it on the page- this is taking the time to complete the operation,

Can I have sample code, which accepts multiple rectangles(list/dictionary/array) and places it on to the page in one-go to save the individual rectangle execution time?

@cyginfo

We are afraid that placing rectangles as images is a page level operation and may not be added to whole document at once. Therefore, it is imperative to iterate through each page and perform the operation as per your requirements.
