We have an rocket.chat installation and I’ve read several times, that there should be a preview or direct “open” for PDF-Files. f.e.: [3.6.0] Does not render pdf previews · Issue #18740 · RocketChat/Rocket.Chat · GitHub
Version of Rocket.Chat Server: 3.13.2
Operating System: Ubuntuu
Deployment Method: snap
Windows-Client: 3.2.2
OK - I had to go read why this happens and the answer is here:
## `registerFieldTemplate` is deprecated
hmm it's true :(, we don't encourage this type of customization anymore, it ends up opening some security holes, we prefer the use of UIKit. If you feel any difficulty let us know
## `attachment.actions` is deprecated
same reason above
## `attachment PDF preview` is no longer being rendered
it is temporarily disabled, nowadays is huge effort render the previews and requires the download of the entire file on the client. We are working to improve this :)
Some PRs that point to it.

Based on the comment https://github.com/RocketChat/Rocket.Chat/pull/10519#issuec… omment-439094206.
Essentially it would be OK if you limited it to say 1Mb PDFs, but people want a 50mb PDF preview and that grinds the system to a halt.
So to keep performance under control it is disabled at least for now.
Thank you the information. Is there another way to optimize the way of opening the PDFs? Currently they have to be downloaded to a folder and than you have to open them from there. Isn’t there a way that PDF-files are opening instant?
Possibly - it probably needs a different link to open in application rather than download?
This is the html for the download link that I copied from open.rocket.chat for a test pdf I uploaded in the #sandbox channel.
You might want to take a look at it.

Anything new about pdf view inside RocketChat? Is there any way to enable it? We are missing that feature
