I use pdfbox to generate images from all the pages of a PDF file. File is given in an URL.
public String Pdf2Image(String html, WebDriver driver){
URL url=new URL(GlobalVariable.url);
HttpURLConnection connection=(HttpURLConnection)url.openConnection();
InputStream is=connection.getInputStream();
PDDocument document = PDDocument.load(is);
PDFRenderer pdfRenderer = new PDFRenderer(document);
for (int page = 0; page < document.getNumberOfPages(); ++page) {
BufferedImage bim = pdfRenderer.renderImageWithDPI(page, 300, ImageType.RGB);
ImageIOUtil.writeImage(bim, GlobalVariable.fileAzon + "-" + (page+1) + ".png", 300);
}
document.close();
}
It doesn’t work for PDF files, which text content couldn’t be copied and printing is disabled. I get following error message during execution. I couldn’t get InputStream .

It is not working. Please try it with that file: http://aplaidshirt.epizy.com/samplePDF.pdf

hello you,
this is totally different scenario, you have to first download pdf file to your disk
2. open file in a browser
3. take screenshot
i am now implementing code for that 
I see, but download function is disabled, I can’t save that file.
hello you,
this works if we have existing pdf file in a disk

hi,
actually this works too, need to click page that pop up will disappear
after that able to click download button
//save and download pdf file from disk
driver.get(“https://gofile.io/?c=WYPqpZ”);
driver.findElement(By.id(“fileInfoDownload”)).click();
Thread.sleep(3000);
hi,
fixed
//save pdf to disk
driver.get("https://gofile.io/?c=WYPqpZ");
Thread.sleep(5000);
driver.findElement(By.xpath("/html/body/div[2]/div/div[10]/button[2]")).click();
Thread.sleep(1000);
driver.findElement(By.id("fileInfoDownload")).click();
Thread.sleep(3000);
no needed to use this method, add comment
//openInBrowser(pdfDir+"/"+pdfFile);
I see, but on that site, where file is originally located, saving is disabled. I just tried to reproduce situation with this demo file: http://aplaidshirt.epizy.com/samplePDF.pdf So please don’t use save function in your solution, because it will not work. Please use original pdf, without gofile file hosting solution: http://aplaidshirt.epizy.com/samplePDF.pdf , but without using file save option.
hi,
what mean saving is disabled?
I am using this site https://gofile.io/?c=WYPqpZ
and works fine
hi,
ok, with this url http://aplaidshirt.epizy.com/samplePDF.pdf use my first script which was posted here
@plaidshirtakos I can open and save (download) the pdf file from the link you provided.
so … what exactly is disabled?
@anon46315158 : This isn’t original file, original file can’t be downloaded. I just reproduced a pdf with same details.
I tried both, but got same error. I attach also an evidence.
got it, so in fact the issue is at the original URL you try to access it, not with the pdf himself.
can you share that URL? (i think not, just asking … but worth to try)
I see it, InputStream is empty, but I don’t know why. Same code is working with your pdf, but not working with mine,
hi,
issue is here
http://aplaidshirt.epizy.com/samplePDF.pdf?i=1
real url has attributes too ?=1
need to investigate it
problem is here
PDDocument document = PDDocument.load(is);
it’s parser issue, maybe need to encode ?=, will try
I tried with this ending too, but it has the same effect, I got error message. PDF file is opened in both cases.
