I have some big size PDF catalogs at my website, and I need to link these as download. When I googled, I found such a thing noted below. It should open the "Save As..." popup at link click...

 <head>
    <meta name="content-disposition" content="inline; filename=filename.pdf">
    ...

But it doesn't work :/ When I link to a file as below, it just links to file and is trying to open the file.

    <a href="filename.pdf" title="Filie Name">File name</a>

UPDATE (according to answers below):

As I see there is no 100% reliable cross-browser solution for this. Probably the best way is using one of the web services listed below, and giving a download link...

After the file name in the HTML code I add ?forcedownload=1

This has been the simplest way for me to trigger a dialog box to save or download.

I found a very simple solution for Firefox (only works with a relative rather than a direct href): add type="application/octet-stream":

<a href="./file.pdf" id='example' type="application/octet-stream">Example</a>

Try adding this line to your .htaccess file.

AddType application/octet-stream .pdf

I hope it'll work as it is browser independent.

A very easy way to do this, if you need to force download for a single link on your page, is to use the HTML5 download-attribute in the href-link.

See: http://davidwalsh.name/download-attribute

with this you can rename the file that the user will download and at the same time it forces the download.

There has been a debate whether this is good practise or not, but in my case I have an embedded viewer for a pdf file and the viewer does not offer a download link, so i have to provide one separately. Here I want to make sure the user does not get the pdf opened in the web browser, which would be confusing.

This won't necessary open the save as-dialog, but will download the link straight to the preset download destination. And of course if your doing a site for someone else, and need them to write in manually attributes to their links is probably a bad idea, but if there is way to get the attribute into the links, this can be a light solution.

Generally it happens, because some browsers settings or plug-ins directly open PDF in the same window like a simple web page.

The following might help you. I have done it in PHP a few years back. But currently I'm not working on that platform.

<?php
    if (isset($_GET['file'])) {
        $file = $_GET['file'];
        if (file_exists($file) && is_readable($file) && preg_match('/\.pdf$/',$file)) {
            header('Content-type: application/pdf');
            header("Content-Disposition: attachment; filename=\"$file\"");
            readfile($file);
        }
    }
    else {
        header("HTTP/1.0 404 Not Found");
        echo "<h1>Error 404: File Not Found: <br /><em>$file</em></h1>";
    }
?>

Save the above as download.php.

Save this little snippet as a PHP file somewhere on your server and you can use it to make a file download in the browser, rather than display directly. If you want to serve files other than PDF, remove or edit line 5.

You can use it like so:

Add the following link to your HTML file.

<a href="download.php?file=my_pdf_file.pdf">Download the cool PDF.</a>
