How to display PDF file in HTML? - html

I have an auto generated PDF file by itext and I need to display that PDF file in HTML. My question is: How to display a local PDF file in HTML using pdf.js? Should that PDF file be generated by some standards?

Implementation of a PDF file in your HTML web-page is very easy.
<embed src="file_name.pdf" width="800px" height="2100px" />
Make sure to change the width and height for your needs.

I use Google Docs embeddable PDF viewer. The docs don't have to be uploaded to Google Docs, but they do have to be available online.
<iframe src="https://docs.google.com/gview?url=https://path.com/to/your/pdf.pdf&embedded=true" style="width:600px; height:500px;" frameborder="0"></iframe>

1. Browser-native HTML inline embedding:
<embed
src="http://infolab.stanford.edu/pub/papers/google.pdf#toolbar=0&navpanes=0&scrollbar=0"
type="application/pdf"
frameBorder="0"
scrolling="auto"
height="100%"
width="100%"
></embed>
<iframe
src="http://infolab.stanford.edu/pub/papers/google.pdf#toolbar=0&navpanes=0&scrollbar=0"
frameBorder="0"
scrolling="auto"
height="100%"
width="100%"
></iframe>
Pro:
No PDF file size limitations (even hundreds of MB)
It’s the fastest solution
Cons:
It doesn’t work on mobile browsers
2. Google Docs Viewer:
<iframe
src="https://drive.google.com/viewerng/viewer?embedded=true&url=http://infolab.stanford.edu/pub/papers/google.pdf#toolbar=0&scrollbar=0"
frameBorder="0"
scrolling="auto"
height="100%"
width="100%"
></iframe>
Pro:
Works on desktop and mobile browser
Cons:
25MB file limit
Requires additional time to download viewer
3. Other solutions to embed PDF:
https://mozilla.github.io/pdf.js
https://pdfobject.com
https://viewerjs.org
IMPORTANT NOTE:
Please check the X-Frame-Options HTTP response header. It should be SAMEORIGIN.
X-Frame-Options SAMEORIGIN;

If you want to use pdf.js, I suggest you to read THIS
You can also upload your pdf somewhere (like Google Drive) and use its URL in a iframe
or
<object data="data/test.pdf" type="application/pdf" width="300" height="200">
test.pdf
</object>

you can display easly in a html page like this
<embed src="path_of_your_pdf/your_pdf_file.pdf" type="application/pdf" height="700px" width="500">

In html page for pc is easy to implement
<embed src="study/sample.pdf" type="application/pdf" height="300px" width="100%">
but pdf show in mobile by this code is not possible you must need a plugin
if you have not responsive your site. Then above code pdf not show in mobile but you can put download option after the code
<embed src="study/sample.pdf" type="application/pdf" height="300px" width="100%" class="responsive">
download

The simplest way is to use,
<iframe src="pdf-link">
</iframe>
and if its still getting downloaded instead of viewing, check the server response header, it should have, Content-Disposition:Inline and not, Content-Disposition:Attachment.

The element is supported by all browsers and defines an embedded object within an HTML document.
Bottom line: OBJECT is Good, EMBED is Old. Beside's IE's PARAM tags, any content between OBJECT tags will get rendered if the browser doesn't support OBJECT's referred plugin, and apparently, the content gets http requested regardless if it gets rendered or not. Reference

I've had something similar before and used normally tags

but it's interesting to find out some other ways as above!

Also this method is useful:

Update - Adobe PDF Embed API
Adobe released their Adobe PDF Embed API which is completely free. Since they created the PDF format itself, their API is probably the best for this.
It delivers the highest quality PDF rendering available.
You can fully customize user experience and choose how to display a PDF.
You will also have analytics on PDF usage so you can understand how users interact with PDFs, including time spent on a page and searches.
All you have to do is create an api_key and use it in the code snippet.
Displaying PDF as buffer (local file for example)
Here is the example of the code snippet that you can just add to your HTML and take advantage of their API for displaying PDF if you have the buffer (local file for example).
<div id="adobe-dc-view"></div>
<script src="https://documentcloud.adobe.com/view-sdk/main.js"></script>
<script type="text/javascript">
document.addEventListener("adobe_dc_view_sdk.ready", function(){
var adobeDCView = new AdobeDC.View({clientId: "api_key", divId: "adobe-dc-view"});
adobeDCView.previewFile({
content: { promise: <FILE_PROMISE> }
metaData: { fileName: "file_name_to_display" }
}, {});
});
</script>

You can use
<iframe src="your_pdf_file_path" height="100%" width="100%" scrolling="auto"></iframe>
Or, if you want to make it take up the whole page:
Link

I understand you want to display using HTMl but you can also open the PDF file using php by pointing out the path and the browser will render it in a few simple steps
<?php
$your_file_name = "url_here";
//Content type and this case its a PDF
header("Content-type: application/pdf");
header("Content-Length: " . filesize($your_file_name ));
//Display the file
readfile($your_file_name );
?>

The answer provided by gofilord is right but I might also add that if you create an empty bucket to pour your pdf into you should give it a src="" like...
<embed id="fooEmbed" src="">
...in the HTML and in the javascript...
document.getElementById('fooEmbed').src = 'bar.pdf';
...it will work. If instead you do this...
<embed id="fooEmbed">
...it will not work.

If you're working with a local file this is the solution that worked for me.
const objectUrl = URL.createObjectURL(file);
<iframe src={objectUrl} width="100%" height="100%" />

iframe sandbox not respecting multiple allow permissions

I am trying to embed an Adobe Portfolio into an iframe without much luck. I need to include both images (which appear to have a JS dependency) and links to open in a new window.
The iframe"standbox" directive is not behaving.
I have tried many permutations of other directives and narrowed it down to "allow-scripts" and "allow-popups" that work separately but not together.
I suspect this is something to do with Adobe Portfolio itself but cannot figure out why!?
Please note - code snippet doesn't run fully as expected within stack overflow site - probably because they have their own standbox directive!
<html>
<head></head>
<body>
<style>
.fl {
width: 300px;
float: left
}
</style>
<div class="fl">
<h1>Images working</h1>
<h3>sandbox="allow-scripts" <br/> (script appear to be needed for images)</h3>
<iframe src="https://picturelinktest.myportfolio.com" sandbox="allow-scripts" height="350" width="200" ></iframe>
</div>
<div class="fl">
<h1>Link working </h1>
<h3>sandbox="allow-popups" <br/> works locally but seems not to work in this tool!?!?</h3>
<iframe src="https://picturelinktest.myportfolio.com" sandbox="allow-popups" height="350" width="200"></iframe>
</div>
<div class="fl">
<h1>Not working when both standbox directives are defined</h1>
<h3>sandbox="allow-scripts allow-popups"</h3>
<iframe src="https://picturelinktest.myportfolio.com" sandbox="allow-scripts allow-popups" height="350" width="200" ></iframe>

How to add watermarks to a pdf that has already embed in html code?

I am displaying a pdf in an iframe in my webpage. I am trying to add watermarks like "Sample" in the pdf file. Is there any possible way to do it with Javascripts, HTML, CSS or Coldfusion11?
In my webpage, depending on the user roles, I use the iframe to either disable the toolbar so that the users can't print or download the pdf, or enable it.
<cfif userroles EQ "admin">
<div style="text-align:center">
<br>
<h1>ENABLE PRINTING AND DOWNLOAD</h1>
<iframe src="myFile1.pdf" frameborder="0" height="500px" width="100%"></iframe>
</div>
<cfelse>
<div style="text-align:center">
<br>
<h1>DISABLE PRINTING AND DOWNLOAD</h1>
<iframe src="myFile1.pdf#toolbar=0&navpanes=0&scrollbar=0" frameborder="0" height="500px" width="100%"></iframe>
</div>
</cfif>
As what #Miguel-F said in his comment, I can use use cfpdf to add watermark as shown in examples in here and here.
What I've done is abit different, using a transparent div in front of the iframe. It does its job, and I can modify the "watermark". Below is my code.
<div style="position:relative; top: -250px; font-size: 150px; color: grey; transform: rotate(-45deg);"/>SAMPLE</div>
Thanks to all who guided me.

How to embed PDF file with responsive width

I'm embedding pdf files using something like this:
<div class="graph-outline">
<object style="width:100%;" data="path/to/file.pdf?#zoom=85&scrollbar=0&toolbar=0&navpanes=0" type="application/pdf">
<embed src="path/to/file.pdf?#zoom=85&scrollbar=0&toolbar=0&navpanes=0" type="application/pdf" />
</object>
</div>
It works but I want to set the pdf width to match the width of the containing div. Currently it shows up like an iframe with scrollbars, so to view the entire pdf, you have to scroll right to left. I want the pdf to fit the width of the container.
How do I fix this? I'm supporting IE8 and up.
Here is a jsfiddle: http://jsfiddle.net/s_d_p/KTkcj/
Simply do this:
<object data="resume.pdf" type="application/pdf" width="100%" height="800px">
<p>It appears you don't have a PDF plugin for this browser.
No biggie... you can <a href="resume.pdf">click here to
download the PDF file.</a></p>
</object>
If you're using Bootstrap 3, you can use the embed-responsive class and set the padding bottom as the height divided by the width plus a little extra for toolbars. For example, to display an 8.5 by 11 PDF, use 130% (11/8.5) plus a little extra (20%).
<div class='embed-responsive' style='padding-bottom:150%'>
<object data='URL.pdf' type='application/pdf' width='100%' height='100%'></object>
</div>
Here's the Bootstrap CSS:
.embed-responsive {
position: relative;
display: block;
height: 0;
padding: 0;
overflow: hidden;
}
I did that mistake once - embedding PDF files in HTML pages. I will suggest that you use a JavaScript library for displaying the content of the PDF. Like https://github.com/mozilla/pdf.js/
<embed src="your.pdf" type="application/pdf#view=FitH" width="actual-width.px" height="actual-height.px"></embed>
Check this link for all PDF Parameters: https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#page=7
Chrome has its own PDF reader & all parameter don't work on chrome.
Mozilla is worst for handling PDFs.
<html>
<head>
<style type="text/css">
#wrapper{ width:100%; float:left; height:auto; border:1px solid #5694cf;}
</style>
</head>
<div id="wrapper">
<object data="http://partners.adobe.com/public/developer/en/acrobat/PDFOpenParameters.pdf" width="100%" height="100%">
<p>Your web browser doesn't have a PDF Plugin. Instead you can <a href="http://partners.adobe.com/public/developer/en/acrobat/PDFOpenParameters.pdf"> Click
here to download the PDF</a></p>
</object>
</div>
</html>
Seen from a non-PHP guru perspective, this should do exactly what us desired to:
<style>
[name$='pdf'] { width:100%; height: auto;}
</style>

Iframe Loading image and IE

I'm loading an Iframe from an External server of mine onto my webpage, and I wanted a loading image, because sometimes it take a good 10 seconds to load. All is well in Chrome but in IE nothing.
<center>
<div style="background: #ffffff url(http://mentalized.net/activity-indicators/indicators/simon-claret/progress_bar.gif) no-repeat 50% 5%;">
<iframe src="http://x.x.x.x/panel.php" allowTransparency="true" width="100%" height="450px" scrolling="no"></iframe>
</div>
</center>
My other question is, is there a better way of doing this? I can't use ajax because it's an external server, but is there a better way of doing a loading image with an iFrame? Thanks!
Try putting the style with the background image information on the iframe itself, rather than the separate div.
<iframe src="http://x.x.x.x/panel.php" allowTransparency="true" width="100%" height="450px" scrolling="no" style="background: #ffffff url(http://mentalized.net/activity-indicators/indicators/simon-claret/progress_bar.gif) no-repeat 50% 5%;"></iframe>
