I am trying to delete pages from a pdf document and keep getting Bad parameter which prevents me from deleting pages, how can I delete a page or pages from a pdf file?
This clearly seems to be a file specific issue. If you are using Acrobat, you may try to run the Preflight tool Analyzing documents with the Preflight tool (Adobe Acrobat Pro) to check problems related to fonts, images etc...
If you can't find any issue with the file and the file is not an interactive form or has layers. Click File>Print > choose Adobe PDFPrinter to print this file with. And try the workflow again. Let us know if that helps.
If you have already found a solution to this issue, please update the thread with your findings that will help others.
