If your PDF has downloaded, but when opened the file was blank, or you see a error message without any description, then it's most likely that there was an issue with the content you have submitted to convert to a PDF. For web links make sure the link is publicly accessible without needing to login, for HTML content, try saving the HTML as a file on your computer and opening it in your browser, if the page is blank or there are errors then you may need to fix something in your HTML before it will successfully convert to PDF.

Check that the web link address is correct and can be accessed publicly without logging in.

Currently the only fonts that are supported directly when converting by HTML are Open Sans and Noto Sans, but any font can be used by loading it externally from the HTML code using a service like Google Fonts

Web pages often contain a lot dynamic content, including JavaScript, images, CSS and other files that are loaded remotely when the page is opened. These need to be downloaded into the rendering engine when the PDF is created and if there are a lot of external files to load, sometimes it might reach a limit on the server and timeout, or you may need to wait a while before it finishes.

A web page can have any length of content, and sometimes due to the way their layout displays in print media and PDF they can result in PDF files that are too long to process in a single request, when this happens the content becomes cutoff and the completed part is returned as a PDF file download

This will only work when the web page is publicly accessible without any login. Even though you are logged in to the website on your browser, our server will not be able to open the same web page as it must open the page from a new session and does not have access to the logged in session on your browser. An alternative way to download the same page as a PDF is to copy the HTML from that page into the HTML editor and generate the PDF that way, keep in mind however that any other external files loaded by that HTML page may not be accessible by our servers either if they require you to be logged in, if this is the case the PDF may look like it's missing parts of the page.
