I was wondering if it is possible to open a pdf file (located on a web server) in a web browser, edit it and then save it with the changes. Basically what I need is to open, edit and save a certificate protected pdf file in my web browser, without ever having to download a copy to my desktop. The pdf file contains textfields that needs to be filled out with text before saving the changes.
I know that it is possible to view pdf files in a browser, but im unsure if it is possible to edit it when it is protected by a certificate.
What you are asking can be performed in the following methods: First which is the simplest way is to use Adobe Forms server. If you would like to use your own PDF, you will need to extend reader extensions display the form in a frame and perform cross scripting to tell the form to post itself to the server. Note: read Adobe Reader Extension licensing extending reader extension has restriction on usage.
Obviously you can enable reader extension allow user to download edit and upload the file to your server.
Certified forms means you cannot change the form structure but you can fill the form and save it (if it is reader extension enabled)

With the latest version of Firefox (107) it is now possible to edit and sign PDF documents within the browser preview window.
But how can I upload an updated version of such a PDF file back into my Web Application?
Is there any kind of JavaScript API I can use?
There is much overlap between PDF web editing browsers and Browser editing PDFs
the data is pulled down locally and the binary application edits the data however for a PDF, that then requires a local save as a new combined PDF. here we can see a visual reminder.
In Firefox or Chrome there are slight differences but the core need is to resave the PDF as a clients local file.
Chrome has inking
And Firefox uses a slightly different overlay but again the conjoined local data must be first saved as a new PDF.
either by print
or the top right Save (again) AS
Thus to achieve your goal you need to ask the annotator user to upload their masterpiece. However you cannot easily do that in the sandboxed page (with work frame) it needs to be after a user signal such as press button here to upload where-ever IF you were able or bothered to save as a new pdf.
The below is the line of code I'm using it currently which converts ppt to pdf, however I want to protect pdf , Is there any possibility
PowerPointapp.ActivePresentation.SaveAs path & pdffileNm & ".pdf", 32
This is not possible with the default vba functions available!
See this, not tested by me, example of using an external library to save pdf with password in the past.
Protecting a PDF is not permanent, once the file is opened (using the users decryption key provided by handing over the password), the contents are available to the new owner to add comment or fill forms or otherwise modify by print or text edit or remove watermarks.
Adobe reader will use different parts of those keys to reduce user writes, but no other editor has to.
Browsers need to edit PDF in exactly the same way so my Firefox pdf reader allows me to correct / change web page content or the embedded pdf contents, exactly the same as any other browser or pdf viewer or editor can. The only protected PDF is an unpublished one.
I'm trying to find a way to host some fillable PDF forms on our website that people can download, fill out, and then they have a SUBMIT button on it that would 1) upload the completed form to a folder on our web server as a PDF file, and then ideally 2) email a direct link to the file on the server. I know how to add the button, just not clear on the actions side for this scenario.
Adobe docs have some info here, https://helpx.adobe.com/acrobat/using/publishing-interactive-pdf-web-forms.html, but nothing specific to what I need.
Does anyone have any experience with this? And if it's even a realistic goal given the number of different PDF readers, browser-based viewers, etc and how it would be supported by all?
Thanks in advance
Am currently working on a web application which receives the encoded text from the web service and am decoding & saving as a PDF file. Once the user clicks for the details then I am supposed to display the PDF file in the web browser.
What is the best practice to display the PDF file in the browser? Am using VB.Net 2003
All you need to do is set the link to point to your pdf file. And if the user has any PDF reader installed, it will be opened using that reader.
The name you Want to Show as Link
EDIT:
The other way, if you dont want to display as link and directly open the file, is to set the correct MIME type in the headers, so that the browsers can detect it as PDF file instead of HTML file.
Response.AddHeader("content-disposition","inline;filename=YourPdfFileName.pdf")
Response.End
I've got a form that I downloaded, I'd like to prefill some content on the form (this is easy using cfpdfform).
Where it gets tricky is I would like to allow the user to modify the contents of that form, and then somehow have those modified contents accessible to me. I didnt build the source PDF so I dont know how to allow the user to "save" the new contents so they can be read.
Any ideas on where I might start on this one?
You can also use the cfpdfform tag to read/write data to a PDF file which has a form. The important thing is that the PDF document already have the form fields available, or that you add them.
I just recently completed a task where I had to have a user fill out a normal web form, and then create a filled version of an existing PDF document. It worked like a breeze!
I think that depending on what you are trying to accomplish, having the user fill out the data in a web form is less confusing than serving up a PDF and expecting them to save that to update a file on a remote server. Just my opinion, though.

It's possible for users to complete most PDF forms in Adobe Reader, but when user's try to save the changes they get a popup prompting them that the PDF cannot be saved and would need to upgrade to Adobe Acrobat to have this functionality.
Since Acrobat 7 (or possibly) 8 it's possible to create a form so that it can be completed and saved in reader. In Acrobat open your PDF, and select Advanced -> Enable usage right in reader from the menu. This will prompt you to save the form and then anyone using Adobe reader can complete it.
Once that's done you can open the form in ColdFusion, populate some of the fields and serve it up to the user. Once they fill it in, save it and get it back in ColdFusion you can read the contents using the PDF related tags.
Please note: It's currently not possible to set the "enable usage rights in reader" flag from ColdFusion, you need a copy of Adobe Acrobat or access to Adobe LifeCycle server to do this.
