Technical tips and tricks



What is the Function Key

The function keys or F keys on a computer keyboard named F1 to F12, are keys that have a special function defined by the operating system or a program that is running. They can be combined with the Alt or Ctrl keys.

Function Keys of Keyboard F1-F12

On laptops

On some keyboards and smaller notebooks, the F keys may have a dedicated function, such as changing screen brightness, volume, or other device-specific functions. On these keyboards, you can press a separate Fn key to indicate that you want to use the key as the standard function key. For example, on the MacBook Pro laptop, the main function of the F12 key is to increase the audio volume. If this key is pressed while the Fn key is held down, it is saved as F12 and triggers the software functions configured to use that key.

If you prefer not to press the Fn key to access your function keys, you can configure the keyboard to treat them as standard function keys in your control panel or system settings.

If your keyboard does not have a row of function keys, they are probably configured as secondary functions on the other keys. Look for other labels on your keys or consult your computer's manual for more information.

The following is a list of some of the most common function key functions for Microsoft Windows and Microsoft applications, as well as others for Mac OS. As mentioned above, not all programs support these function keys and the function keys on your keyboard may perform tasks other than those mentioned below. For additional specific shortcut keys and function key examples, please see our general index of shortcut keys.

How to Combine Multiple Files into a Single PDF

Combine Multiple Images into One PDF

create pdf from multiple images

Technology tips and tricks:

PDF printing is a widely available option these days, and it's even easier with support for operating systems on most platforms and even on mobile. So, although creating a PDF file from a Word document or a combination of documents is very easy, what if you want to combine a set of scanned pages in JPG format into a single PDF file to share with another user?

This will be a little easier if you use Windows 10 because Microsoft has added this as a native feature to its latest operating system. However, we will also recommend third-party tools that can do the work on older versions of Windows.

In addition to being a quick way to share a set of images in a convenient format, this feature is crucial for merging scans of documents or slides into a single file.

Speaking of which, the Microsoft Office Lens app, available for free on Android and iOS, turns your Smartphone into a portable scanner that can capture documents, business cards, receipts, whiteboards, and more. We had a good impression after recently using the application to send a bunch of signed documents, after which we used the built-in functionality of Windows 10 to combine them.

Combine Images into a PDF in Windows 10

Complete the instructions below to combine images into a PDF in Windows 10 without using additional software.

Step 1: Open File Explorer and navigate to the folder containing the images you want to combine into one PDF.

Step 2: Select all the images you want to combine in one PDF. To select images, hold down the Ctrl key and click (one by one) on all the images you want to select.

Step 3: Once images are selected, right-click and click Print. This will open the Print Images dialog box.

Step 4: Select Printer as Microsoft Print to PDF, select the quality, and select whether to add one image per page or to include multiple images into one PDF page.

Note that

Step 5: Finally, click the Print button to display the Save Print Result As dialog box.

Step 6: Type a name for the PDF file, then click the Save button to combine the selected images into a single PDF file.

Once the PDF file is ready, you can open it to view the images.

Combining Many Images into a Single PDF File in Windows 8, 7 or Older

If you try this process on Windows 8 or earlier without installing a third-party tool, Windows itself will only allow registration as an XPS or OpenXPS document, and not as PDF. 

That said, we included a list of the top five PDF creators.

1. PDFCreator
2. DOPDF
3. PDF24 Creator
4. PDFFactory
5. Bullzip PDF Printer

combine multiple jpegs into one pdf

Working with one of these utilities should be simple, especially if you have read the Windows 10 section, but we will summarize the process again.

First, download and install one of these programs to add a PDF print driver to Windows (note ... we tested PDFCreator on Windows 8 and 10, although we stick to the built-in function of the latter unless otherwise indicated).

convert multiple jpg to one pdf

Make sure your images are in a single folder and that the files are named to match the order in which you want them to appear in the PDF file. Select all files, right-click the first, and press Print to open a prompt with options that include a drop-down list of printers in which you should find the latest installed PDF tool. Once selected, you can print the PDF.

You can also launch PDFCreator itself and follow its graphical interface.

combine multiple files into one pdf

It should be noted that we could not differentiate between the image quality of the Windows 10 native PDF print option and the file created by PDFCreator with its highest image quality setting.

On the contrary, the integrated tool has generally performed better. It was a little faster when creating the file, its output file was much smaller (10MB vs. 60MB) and it was correctly getting the default image orientation (the PDFCreator output had our images of landscape in portrait).

This can be fixed in one or two clicks of course, but it seemed useful because most people are likely to click without changing any settings.
