There are usually several ways to save a PDF-file from a webpage: 1 Use browser add-ons: Many browser add-ons come with the option to open and save a webpage's PDF-files. For example, the extension for the Chrome-based browser is the PDF-password Manager. 2. Use third-party tools: Some third-party tools can help save the PDF-files in the webpage. For example, the adobe Acrobat Reader allows users to directly read and save the webpages in the document. 3. Use the local file manager: If you have saved the webpage in a local file, you can use the local file manager to open the file and select the PDF-file to save. For example, you can use the "Open" command in the "file" menu to open the web file and then use the "Save As" option to save the document to a local file. Regardless of the method used, you should ensure that the PDF-file is saved in a secure location to prevent unauthorized access.
