I have a PDF file being viewed on the browser.
I want to disable Save, Download and print option of the PDF file.
Please help.
Try this:
<object width="100%" height="100%" type="application/pdf"
data="yourpdffile.pdf#toolbar=0" id="pdf_content"><p>Document load was not
successful.</p></object>
Make sure you add #toolbar=0 in the data attribute after your pdf file.
You can use iframe to your own version of PDF viewer.
Use pdfJS and when showing viewer.html just remove these buttons.
If user is viewing it on it's own tool, than you can't control it.
Google Drive can disable the PDF functions to download, print and copy as of 2015.
Note however, that users can still print using the browser print function.

As others have noted, once the pdf is being viewed by the user, they can save it.
If you are just wanting to obfuscate the download, you could disable the menu as described but to truly prevent downloading of the PDF, then only thing you could really do is a little crazy but not impossible.
You could convert it to images and show those instead. Not an ultimate solution as they would still be able to save each image, but at the very least they would not get a PDF file from it (or at least if they are smart enough to convert the images to one, it would not be the same pdf file or content)
There are many tools to do this and you'd have to implement a viewer with paging but this might achieve what you want.

I am interested in messing with the built-in PDF viewer of Microsoft Edge. I know you can inspect its files in the Dev console, but I would like to know where these files are actually located so I can change them to alter/add some functionality.
Another possibility would be to run a user script when a PDF is loaded, but tampermonkey does not seem to work when a PDF file is opened in Edge.
Why I want to do this: I would like to see whether I can implement additional functions that I'd like to use in the PDF viewer. I know there are pdf js libraries out there, but I feel like none of them display pdfs as nicely as Edge does and I haven't found one that allows drawing on pdfs.
You can see the edge_pdf source code by inspect the page ,then click the Source panel, it show all the resource which edge_pdf loaded.
I need to embed a PDF file in an HTML page for the users to see it on every major device.
Most of the approaches work fine on desktop but they start to show problems on iPad devices. The PDFs are no longer scrollable if placed inside an iframe or embed tag.
I used the following techniques to overcome the problem:
1) Using pdf-image for node and converting the PDF to images and then sliding them in a div.
The problem in this approach is that the image quality gets degraded and is not suitable for viewing on Web.
2) Using PDF.js by Mozilla
It works fine on every device but it makes the page extremely slow and unresponsive on iPad
3) Using Google PDF viewer
<iframe src="https://docs.google.com/viewer?url=http://public-Url-of-pdf.pdf&embedded=true" frameborder="0" height="500px" width="100%"></iframe>
The problem with this approach is that I need to make my PDFs publicly available which I don't want to do for security reasons.
None of the above method is working for me. Is there any solution available to embed PDF in a page which works on iPad also.
One of my colleagues told me about using LibreOffice(open office) headless to embed PDFs in my page but I cannot find any documentation about it usage?
Can anyone please help? :(
Thanks in advance!

Try above one for pure HTML. But another option is if you'd like to use with javascript, try Pdf.js by mozilla. https://github.com/mozilla/pdf.js
I think the simplest way to embed a PDF into a web page is to use the object tag:
<object data="assets/test.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="assets/test.pdf">click here to
download the PDF file.</a></p>
</object>
What the code above will do is:
- If the user browsing your site has a PDF viewer plugin (which is included by default in some browsers) it will open the PDF in the browser:
- If the user does not have a PDF viewer plugin, they will be presented with a link to download the PDF and view it on their site.
I spent a lot of time with this issue and finally reached a solution for embeeding PDFs in a HTML files, also inspired by this post. You mentioned that "converting the PDF to images and then sliding them in a div" was not satisfactory due to quality problems. Here I experienced the same since the images were blurry.
However, I tried converting the images to SVG instead of PNG and the situation was a different one: The fonts were crystal-clear when embedding the image like below:
<object type="image/svg+xml" data="https://ik.imagekit.io/nudvztcu8my/pdf2svg_example_Ft2FQgqWaG.svg">
<!-- Your fall back here -->
<img src="https://ik.imagekit.io/nudvztcu8my/pdf2svg_example_Ft2FQgqWaG.svg" />
</object>
You can directly paste that snippet into a HTML file and you will see the result. For producing this example I used a ramdom PDF from ArXiv.org and converted it to SVG using an online converter.
There are also free command line tools like pdf2svg or commerical APIs like Aspose and probably it is worth examining which approach gives the best results.
You can easily build a slider which is loading the SVG images dynamically and it is even possible to scale them to different viewports due to the vector character of the SVG images. The approach so far worked for all PDFs I tried but probably it is recommendable to implement a fallback solution still using PNGs.
Hi,
I have a banner on my site made in flash. Its an animation that ends with a sequence showing buttons which the user can click to navigate to inner pages. Since flash seems to be dead soon I would like to replace that with html5 friendly code. Is it possible to have a program such as Adobe Flash CS5 to convert the full movie for me into javascript code? Or I have to write the javascript all by myself from scratch?
Thank you.
You can use Flash CC to publish you flash file into HTML canvas base structure. Steps -
Open file in Flash CC select commands->Convert to other Documents.
Folder Select HTML 5 Canvas from Dropdown and press OK. Now open
newly created Flash file and publish. It will give you the canvas
base html file.
The html and javascript you get is in organized format and you can even edit code as well.
Hope it solve your problem.
I'm working on generating pdfs that contain the image from a html canvas element. I've managed to get an implementation of that working, but I'm having trouble opening the result in a useful way.
PDF.dataURI() returns a string that looks like data:application/pdf;base64,BASE64_ENCODED_PDF_HERE.
I'm currently using window.location = certificate.dataURI() to open up the pdf. I already tried window.open, but Safari wouldn't play nice with it.
RESULTS:
In Firefox, this saves a file that is a random name, followed by .pdf(1).part.
In Safari (desktop and mobile), it opens the PDF in the same tab, but doesn't bring up any pdf viewer interface.
In Chrome, it opens the PDF in the same tab and brings up the PDF interface.
Basically, my question is how to open a string of that format inside of the browser as a PDF, ideally in a new tab.
Any thoughts?
You can use iframes to view the pdf like below
<object data="data:application/pdf;base64, your_base64_data" type="application/pdf">
<iframe src="https://docs.google.com/viewer?&embedded=true"></iframe>
</object>
have you tried document.location.href ?
you can try to control UI interface for PDF viewer from appropriate options inside generated pdf but browser may ignore it, so as al
I'm making an app where i want to show the user a range of base64 encoded picture. They are shown by using data-url. If the user wants to save a picture, it can simply rightclick and save as (or drag it into a folder).
Are there any way to control the sugested filename? Right now Chrome just sugest "download" and doesn't even recognize it as an image. Can this be done in any way?
I only need it to work in Chrome.
Thanks for any help
Make sure you are setting the proper mime type for the image in the data uri. Doing this fixed the file extension in Chrome 17, for me. The file was downloaded as "download.png", and opened fine.
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA
AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO
9TXL0Y4OHwAAAABJRU5ErkJggg=="/>
However, if you really need full control over the filename, you can exploit the html5 "download" attribute of the a tag, to set the filename, and create a Blob object with your image data that will be used be downloaded.

The current specification does not make this possible.
