I've a document library in SharePoint 2010 with some pdf. When i click on a pdf, it proposes save as in place of open.

How to achieve this?

I added this in my master page:

 $(function () {
    $("a[href$='.pdf']").attr("target", "_blank");

You have to make sure the following things in order to open the PDF in browser.

There are two options available

  • Browser File Handling should permissive for the web app, you can change it using the Central Admin > Manage web Application> Web Application General Settings. this is kind of security risk.
  • Explicitly add PDF to allowable list of MIME types in SharePoint 2010. .Use the below code to add MIME type

    -#Get web application object   
    $webApp = Get-SPWebApplication "web app url"   
    -#List all allowed MIME types for this web application
    -#Get web application object again
    $webapp = Get-SPWebApplication "web app url"  
    -#Add PDF to allowed MIME type list    
    -#Commit changes

  • If you are using Adobe Acrobat, you will need at least version X of the software. Also, check if your Acrobat to browser integration is working. – Arsalan Shahid May 20 '15 at 21:02
  • I would definitely not recommend setting it to permissive in production and instead intentional declare it's use (Waqas 2nd bullet). and as far as opening in the browser itself - that will also depend on the browser and/or application plugins being enabled. – Jesus Shelby May 20 '15 at 21:08
