PDF compression

Thanks to tools like Canva, my clients are increasingly able to create their own PDF files for event flyers, etc. However, they often create files that are very large. Recently a client uploaded a 14MB file. I manually compressed it via Acrobat and reduced it to 350KB. I don’t want to do this all the time…does Download Manager have capability to reduce/compress PDFs as they are uploaded, or do you have a recommended third-party plugin that is compatible with your plugin?
