I think that the problem sometimes occurs when the web server you are downloading the PDF from does not serve the PDF with the correct MIME type.

When the web server serves a PDF with the correct MIME type, Chrome previews it. When the web server serves a PDF with the incorrect or generic MIME type (application/octet-stream), Chrome downloads it.

If the server returns a Content-Type of text/html Chrome will display/open the PDF directly in the browser. However, if the server returns a Content-Type of application/pdf then the browser will prompt the user to save/download the PDF.

r/chrome on Reddit: Can I force a PDF to open instead of downloading?
May 11, 2018 -

Sometimes I just want to look at a PDF, but when I click on the link Chrome starts downloading it. Is there any way to override this and cause PDFs to always open instead? I'm thinking Chrome does this based on some headers sent by the server, and I'd like to ignore those for PDFs.

Yeah, I know in both cases the data needs to be received from the server. I just want to make things easier for myself. Opening a PDF is a single click process. Downloading is multiple clicks plus having a file I probably don't want and will need to delete eventually.

Download a PDF file, then when it is done, left click on the download icon at the bottom and select "always open this type of file" Now It should open any PDF link you click in that window without downloading it to a permanent location.

To undo it go into Options>Under the Hood tab>Clear Auto Opening Settings.

I also have the box ticked, "ask where to save each file before download", not sure if this has any affect on the behavior of automatically opening a file.

There may be some PDFs that chrome cannot display properly, so it offers you to download it to view with another PDF viewer. It is not a full featured viewer like Foxit or Adobe

I use it this way and can find no PDF that chrome has saved, it has to cache it somewhere to read it, but I am not sure where it does.

Is anyone else getting completely fed up with these companies just screwing regular workers by doing the dumbest things you can imagine? For example, not being able to open a .PDF in the default application from a web browser. Like users have been able to do for years? The options are open in the browser or download. WTF is this? At first, I thought it was just Edge, nope it’s Chrome as well now. This keeps coming up more and more and I can’t seem to find a simple solution.

I have a client that is literally about to explode. They don’t want to have to download the pdf and then open it. They haven’t had to do it in years and they don’t want to do it now. Nor are they interested in using edge or any other browser to deal with PDF’s. They honestly open like 50 to 60 pdf’s a day and need all of the stuff in Adobe Pro. It’s literally what they do all day. Now it’s an extra step for god only knows why.

Now it’s on me to find a workaround because these dumbass companies (mainly Microsoft) just don’t care about their customers. Sorry I’m bitching but it’s gotten to a completely unacceptable level of complete ridiculousness.

Does anyone know why they are doing this? IE, a security reason. I’m trying to find a reason to explain to clients why it’s being done. Adobe is a $285 Billion company for a reason. People use the crap out of their software. That probably answers my question of why this happening, money. The clients don’t care about the tech. They just want to get some work done the same way they did it before. Not with extra hoops and jacking around.

So frustrated.

Both Edge and Firefox have a setting to open a pdf in the Windows default application. No idea about Chrome or Brave, I don’t use them.

html - View PDF without downloading - Stack Overflow
On a mobile browser (Android Firefox & Chrome), the link downloads the PDF file and clutters the device. On iOS Safari, the PDF is opening inline in the browser. I would like a consistent experience of viewing the PDF without downloading on any device. It appears that the only option is embed pdf.js on the website - similar to this page, which opens PDF files inside the browser from all desktop and mobile browsers.
