Article in English: Go to the location of the file you want to convert into a PDF, then double-click the file to open it.    If you want to add multiple photos to one PDF, instead do the following: select each photo you want to use by holding down Ctrl while clicking them, right-click one of the selected photos, and click Print in the resulting drop-down menu. You can then skip the next step. If you want to create a PDF of an HTML file, open the HTML file in Notepad by right-clicking the HTML file and then clicking Edit in the drop-down menu. The fastest way to do this is usually by pressing Ctrl and P at the same time, but you might need to click File and then click Print in the resulting menu. Don't be alarmed if you don't have a printer attached to your computer—you're not actually going to print anything. It should be near the top of the menu below the "Printer" or "Printers" heading. A drop-down menu will appear. If you're using a text document or an XPS document, skip this step. It's in the drop-down menu. Doing so selects your computer's "Print to PDF" feature as the method with which you'll "print" your document. If you're using a text document or an XPS document, you'll just click Microsoft Print to PDF in the "Select Printer" section near the top of the window. It's usually at the bottom of the menu, though you'll click Print at the top of the menu if you're using a Microsoft Office program (e.g., Microsoft Word). A File Explorer window will appear. In the "File name" field, type in whatever you want to name the PDF version of your document. Since you're creating a PDF version of the document, you can name the PDF the same thing as the original document and store it in the same location if you wish. On the left side of the window, click the folder in which you want to store your PDF. For example, if you want to save your PDF on the desktop, you'd find and click Desktop in the left-hand sidebar. It's at the bottom of the window. Doing so will save your changes and create a PDF version of your file in your selected save location.
