How to convert a file or picture to PDF on a Windows device

When using Windows, there are a couple of methods you can try if you’re in a pinch. Beware, you might find limitations on the file types you can convert when using these techniques.

The following suggestions are two simple methods to try on Windows. The instructions may vary slightly depending on the version of your operating system.

Method: 1 Converting a file or picture to PDF using ‘Microsoft Print to PDF’

You can convert files using ‘Print to PDF’ on Windows. The ‘Print to PDF’ method can be snappy once you know it, but this approach only works for the following file types:

• Text files
• Microsoft Office documents (like Excel spreadsheets, PowerPoint presentations, or Word documents)
• Photos, but a lot of app-specific picture files are not compatible (like Photoshop files)
• XPS files, which are Microsoft’s proprietary equivalent of a PDF

Follow these steps to convert a file to PDF on Windows using ‘Print to PDF’:

1. Find the file, open it up.
2. Press Control + P to open the print menu, or go to File and then Print in the dropdown.
3. Under the Printer name, select the option for Microsoft Print to PDF.
4. Click Print—don’t worry, you’re not physically printing anything.
5. Choose a name for your new file and click Save.

‘Print to PDF’ is a handy feature, and this method is both fast and simple—but it’s only useful for common Windows file types.

Method 2: Converting a file or picture using Microsoft Office apps

You can convert certain files to PDF on macOS by using the File menu. This method is typically suitable for converting documents to PDF but, again, it only works on a select few file types—such as the following:

Follow these steps to convert your file into a PDF from a Microsoft Office application:

1. Open the file you want to convert
2. Go to File and then select Save as
3. Choose a file path, to set the save location for your file
4. Choose a name for your newly-converted file
5. Use the dropdown menu to select the filetype PDF (*.PDF)
6. Click Save

Bear in mind that this method is useful for converting Microsoft Office files into other formats too. That includes older versions of Microsoft Word and Excel, or ‘open document’ formats like ODT.

How to convert a file or picture to PDF on a Mac

Mac users love PDFs for their compatibility with other devices. If you have an image file from a photo or design app—or just a written document—it’s often possible to use macOS to convert it to PDF.

The following methods will provide a quick method when you’re using macOS. Please note, instructions vary slightly depending on the version of your operating system:

Method 1: Convert a picture to PDF using Preview on macOS

Preview is the macOS image or PDF viewer, so it can’t help much with converting document files. This method works best for the following types of picture or image files:

• PNG files
• JPEGs (or JPGs)
• Bitmaps
• Miscellaneous other picture files
• PSD and TIFF files, which are the only graphic image file format supported

Preview is not as versatile as converting a file to PDF directly within your Dropbox cloud storage. But, to try this method, you can use these steps:

1. Go to the file and select it, select multiple images by holding down the Command key.
2. Use Finder and select File in the top-left corner, to reveal the dropdown window.
3. Select Open With and then click the Preview app.
4. Once Preview opens, select File again to reveal another dropdown menu.
5. Click Export as PDF.
6. Pick a name and a file location.
7. Click Save.

Your new file will be ready to use from your new save location. Preview is a solid macOS app, and offers a simple conversion method, but has a lot of limitations on the file types you can convert.

Method 2: How to convert a file to PDF using the File menu on macOS

You can convert certain files to PDF on macOS by using the File menu. This method is typically suitable for converting documents to PDF but, again, it only works on a select few file types—such as the following:

• Text files
• Microsoft Office documents (like Excel spreadsheets, PowerPoint presentations, or Word documents)
• Files from equivalent Apple applications (like those from Numbers, Keynote, or Pages)

Try the following steps to use the File menu method to convert a file to PDF on macOS:

1. Open the file in its relevant application.
2. Click File from the menu at the top left of the screen.
3. Select Print from the dropdown menu.
4. Select the PDF dropdown in the lower left section of the Print menu.
5. Click Save as PDF then choose a filename and a save location.
6. Click Save.

There you have it! Many apps allow you to save to PDF on macOS. When working with macOS applications it may be smart to just save a PDF version to avoid the need for conversion later.

Looking for a straightforward way to convert to PDF when you can’t access the file menu? Switch a file to a PDF in a few clicks with our free online convert to PDF tool—you don’t even need a Dropbox account to get started.
