How to combine JPEGs into one PDF

6 min read

The Portable File Format, or PDF, was created back in 1993. It started being widely used in the early 2000s and is still one of the most popular file formats out there today. A PDF can include text, images, and graphics, and is generally used for exchanging electronic documents.

Meanwhile, JPG is a digital image format which contains compressed image data. It’s the most common image format used by digital cameras and other image capturing devices, meaning that if you take a photo, it’s likely to come out as a JPEG.

Converting file formats for compatibility, ease of transfer, printing, vieving, and other needs has become a basic part of our life, so it’s necessary to know how to turn JPG to PDF and merge multiple files together. Let’s get right into some of the most convenient ways to combine pictures into one PDF on Mac.

Printing or sending one PDF with multiple images is easier and faster than working with all those images separately, when there's a chance to forget one or two most important ones. Knowing how to combine JPG files becomes even more important in a professional setting where you’d want to make viewing your files more convenient for the receiving party, be it a client or a boss.

Every Mac is equipped with lots of native tools to help you perform practically any task without having to leave the comfort of your computer. The Preview app is a native macOS image and PDF viewer, which also lets you edit them, making it simple to combine multiple JPEGs into one PDF. 

Here’s how to merge pictures together on a Mac:

  1. Select the images you want in your PDF
  2. Right-click and select Open with ➙ Preview
  3. Drag the photos in Preview’s sidebar to rearrange their order
  4. Use the Rotate button to change the orientation of individual pages if needed
  5. Click File ➙ Print
  6. Choose Save as PDF in the drop-down menu, or Send in Mail, to send the PDF directly as an attachment
  7. Name the file and choose a location to save it, then click Save

Once you open your newly created PDF, you can add more images by dragging them into the document. To delete an image, right-click it and select Move to Trash. If you want to make a PDF private, you can add a password by exploring the document's Security Options.

The only major downside of this method, as it might have become apparent, is the need to convert every image into PDF format before being able to perform JPEG merge.

One of the main reasons for wanting to save multiple images as one PDF is the need to somehow resize an image, without compromising its quality, of course. Although converting JPG to PDF would let you compress the PDF file, achieving a smaller file size than JPEG, it would oftentimes still damage the quality of the original high resolution image. The best solution here would be to try an app created specifically for this.

PDF Squeezer quickly compresses PDF files, while preserving the quality and original file look. The app’s interface is minimalistic to help you stay focused on the task at hand. PDF Squeezer will save you time reducing the size of multiple files with its batch resize feature and the ability to compress all files in folders.
