Optimize PDF weight

[jmaupetit]

Purpose

Sometimes people submit huge PDF files (>30Mb), in app rendering is quite slow in this case.

Proposal

We may use optimized PDF files instead of the original ones. Can cloudinary optimize those PDFs?

Cloudinary can upload PDFs as JPG: https://cloudinary.com/blog/uploading_converting_and_generating_thumbnails_for_pdf_documents. This could be interesting to save bandwidth, storage space, and simplify the mobile app. We would only deal with images.

Good idea! If we always keep track of the original file URL, this would be optimal.
