Thank you very much for your interest in Saaspose APIs.
I would like to share with you that there is no limit on the number of files. We only apply limit on the number of API calls and file size. For example, upload a file to the server is one API call and that's it. Regarding file size, with an evaluation account, you can upload files of size upto 1 MB. However, with our paid plans you can upload larger files. So, there is no limit defined on number of files.
I hope this helps. If you still have any confusion or need further assistance, please do let us know.
Thanks & Regards
Saaspose Support Team.
