I bought an online course recently. They mention on their websites that a note will be provided. But in the names of note they provide a 2-page summary for download, and the original note PDFs are not downloadable. I tried to download PDF from their sites via IDM but file corrupted. Even I tried to force copy and pasting into other documents but not successful as it pastes some encoded language. Only way I found to click screenshots of each and every pages on pc and paste into the word. It is very time-consuming. Is there another way to download PDF from their sites? Edit: look like the best way to capture it through screenshot.

Try reverse engineering the DRM. Most DRMs are stupid simple to break. Look at the JS code or the network tab under devtools. Maybe you can get the key.

If all fails, login through a headless browser session using python + selenium and use some quick and dirty scripting to screenshot each page.

I found another site that seems to use the same backend and pdf renderer. I looked at the network tab, and it downloads a .epdf file, but I'm not sure how to open it. If you want to have a go at cracking it, here's a link to it: https://pastebin.com/w6JkNDYH
