What’s the best way to protect a pdf document? Like from being copied shared printed downloaded? I think Google docs offers that. Thank you

I guess there‘s no good way to do that; a ScreenShot works anytime

Yes but I’m asking specifically about if there’s a privacy friendly service that has those features that GoogleDocs has (licking printing, editing, copying, etc.)

You’re pretty much asking for DRM here. Which is very intrusive, expensive to implement/pay for. And never really works. Expect that everything you push on a website, will be available for the end users without any limit (you can’t pull it from them in an easy way). You could provide the person …

Encrypting it with a password. Acrobat will also allow you to add flags that Acrobat reader can’t bypass. It’s all digital pinky swears though. You’ll have better luck with a non disclosure agreement signed by the receiver.

Oh, interesting! Does it work if open inside of a web browser? Does not block you from seeing the source, using a screenshot or your phone camera but definitely a cool (evil proprietary company) feature I concede that. :+1:

If you have the resources and time, you could create your own PDF viewing web service without allowing any printing. I’m sure there is some simple javascript library for convenient implementation.

You still send it down the pipe, no way for you to remove access to it for anyone willing to open their network tab. Hence, a very small barrier overall.

One can program the server to serve a PDF viewer rather than fetching the PDF from the client side and then loading it into a PDF viewer though.

Sorry. I meant “restricting with a password”. Per https://helpx.adobe.com/acrobat/desktop/protect-documents/protect-with-passwords/restrict-printing-editing-and-copying-pdfs.html you have to add a password when you add the restrictions to print/edit.
