Can you set default zoom for PDF's in document library? RRS feed

  • Question

  • Hi We have SharePoint online going strong with our new embrace of 0365.  We have a document library of ~150 PDF's.  Whenever we click one, it opens in the browser and default sets itself to WINDOW SIZE.  However, this makes it almost impossible to read.  All of our employs have to manually set the zoom EVERY TIME THEY OPEN  A PDF (Even one they have opened before).

    I have searched and searched and cannot find anything on this. IS THERE ANY WAY TO SET THE DEFAULT ZOOM IN SHAREPOINT WHEN OPENING PDF'S?

    Thanks.

  • Hi Frumpy,

    As per my knowledge there are no ways to set the default zoom in sharepoint. sharepoint is not opening your document it's the client program or plugin that is rendering your document in browser. If you are using default browser to open the pdf document then it's not possible but if you are using browser plugin like adobe then you can configure it. Here is a link for your reference-

  • Hi Kumar,

    Okay.  I'm not so sure this isn't being driven by Sharepoint.  Before this upgrade the "toolbar" for PDF's opened in the file library looked different.  Luckilly I can open the old site still.. So here's a screenshot of the toolbar I get when I open one in the old sharepoint and the same file in the new sharepoint.  You can clearly see that the old one was opening acrobat in-browser.  I have no idea what the new one is, but it shows up in IE, Chrome and Firefox the same... so I think it's Sharepoint Online (O365) driven:

    NEW:

  • Hi Frumpy,

    Many recent browser versions include their own, native PDF plug-ins that automatically replace the Acrobat and Reader plug-in from Adobe. Installing Firefox 19 or later, for instance, can result in your Adobe plug-in being disabled and replace. SO nothing is related to sharepoint.

    Hi Kumar,

    Unfortunately, that makes no sense.  How could three separate browsers NATIVE PDF view have the exact same toolbar for zooming/rotating/searching/showing page numbers?  If three separate browsers show the same layout for a 3rd party PDF viewer, isn't it more logical to assume it's the website providing an embedded PDF viewer?

  • Hi Frumpy,

    Thanks for your reply, I did more digging on it and you are right. Yes SharePoint is providing it's own PDF control to render document - 

     when you click on the file name sharepoint will make a call to proxy and load this file(which is being loaded from some other endpoint not microsoft) - _layouts/15/serviceworkerproxy.aspx?serviceWorkerUrl=https%3A%2F%2Fspoprod-a.akamaihd.net%2Ffiles%2Fodsp-next-prod_2019-10-18-sts_20191031.001%2Fpdfjsworker-mini-bdb794be.js . I am not sure about it's implementation but it looks like this - https://github.com/mozilla/pdf.js/.

    once the file is loaded it will make another call to download the file content using download.aspx and then the result will be rendered on your browser.

    Unfortunately there are no ways to set default zoom for this PDF viewer control.

    I have also tried this one - https://acrobat.adobe.com/uk/en/business/integrations/microsoft-sharepoint.html in my o365 tenant and even it has not got functionality to set the default zoom in.
