PDF preview or open in a new tab

[Simon.Sturm]

Hello,

I would like PDFs not to be downloaded automatically, but instead to be previewed or opened in a new tab.

Does anyone have a solution for this?

I think it can be influenced by the browser configuration. Zammad is not showing directly inline, because of security reasons, it will always be downloaded.

I think I understand the ask here, and I would agree it would be helpful: You can’t force the browser to use its built-in preview functionality, but you can encourage it by setting the Content-Disposition header to “inline” when serving the request for the file. For example: ‘Content-Disposition: inline; filename=“some_file.pdf”’, would cause Chrome-based and Firefox browsers to open the PDF in-browser, rather than downloading the file. I imagine images would work the same as well.

I‘d suggest not to vote the denied duplicate and vote the favored one instead.

Apart from that, I believe that a software shouldn‘t decide how a browser should open a file for the user. That‘s a browser configuration, no?

I’ve voted over there, thanks for pointing that out.

Here’s the MDN documentation regarding the Content-Disposition header: Content-Disposition header - HTTP | MDN

I’d argue that it doesn’t force the browser to do anything, merely suggests the site’s intent with the content. Obviously, like everything with browsers, they all handle it a touch differently .
