Hello,
I am currently using a!documentDownloadLink in record dashboard to download the documents stored in Appian. Now I need to restrict the users from downloading the documents locally and just provide view option. Need inputs on how can we achieve this “Documents Viewer” functionality
Thanks,
Lobin

To just view documents, you can convert them to PNGs and show them in a gallery. I did this before and it looks nice. To convert the documents from PDF to PNGs you do not want to use the plugin found in shared components because rendering of the pages is rather bad. I created a version with a newer version of the used libraries which does a pretty good job in rendering.

I think we have a plugin for this, I don't remember where I heard or read this. Let me search and revert.

@lobinu If I am not wrong, the plugin being discussed above provides you with an advantage of going through the document contents without downloading them and using the "THUMBNAIL" is a great user experience. But I guess you can't restrict the user from downloading the documents still, they are downloadable.
You may use the other attributes such as "LARGE", "MEDIUM" etc. but I don't think these are great options when there are many pages in the document.

Indeed the plugin converts PDF to PNG inside Appian. It can handle big documents with many pages.You can restrict download by putting the original files in a restricted folder and only make the images available.
