How to stop downloading PDF in an iframe automatically and instead view the file?

Question

I have an iframe on my website that loads a PDF file :

<iframe src="file.pdf" frameborder="0" width="800" height="600"></iframe>

But it's downloaded automatically , I want to view the file not to download it .

So how could I fix this problem?

Answer 1

You need to tell your server to send that file as application/pdf ("PDF")

...

Bonus titbits:
- why do you have a PDF on a website? The web page you're displaying your PDF from already displays things PDF files display
- why are you loading a PDF in an iframe/etc. if you just want it to be downloaded? Why not just link to it

Answer 2

尝试使用embed <embed src="file_url" height="" width="">
