Help removing protection from a PDF file.
I have an app on my phone, ACK Comics. I downloaded few comics on it but they can't be viewed outside the app. It's downloaded in PDF format. Here's a link to the file,
https://drive.google.com/file/d/1aQ4...w?usp=drivesdk How do I know the type of protection on the pdf and remove it? |

If it's DRM protected, you can't. It may be strictly proprietary protection that can't be broken. If so, you would have to find a DRM-free version.

It's is a proprietary encrypted file. A PDF file will have %PDF-1. as the first characters of the file which your comic does not have. It may have been born as a pdf but it has been mutated.
