Dragging and dropping files to the page also works. Dropbox or Google Drive files You can pick PDF files from Dropbox or Google Drive too. Expand the 'Upload' dropdown and select your files.
Step 2: Choose options Page size By default images are placed in a A4 sized PDF page. You can choose different page sizes, including the option to have it fit the image size. Click the Page size dropdown and make a selection.
Page orientation For most users the default auto detected page size will work best. Based on the image dimensions either portrait or landscape is selected. If the image width is larger than its height, then a landscape page orientation is a better fit than portrait. A specific page orientation can be selected from the dropdown, in case you need to override the default.
Image margins By default the image will fill the whole available space on the page, no image margins being added. Want to add a whitespace border around the image? This can be configured either as a small margin (0.5 inch) or a larger margin (1 inch). Reorder images Reorder pages by dragging the thumbnails with your mouse to the correct location. Add more images or pages by dragging files from your computer onto the web page.
